Replacing the resonator of Lada 2110 (VAZ 2110) with your own hands

Gradually, like any part, the additional muffler begins to wear out and ceases to perform its functions. As a result, a specific noise begins to arise when driving a car. However, only replacing the resonator of the VAZ 2110 will help solve the problem. The first distinctive sign that the part is deteriorating is an unusual sound in the exhaust. As a rule, as it wears out, it is installed much more actively. Before changing the resonator of a VAZ 2110 injector 8, you should contact specialists who will check the condition of the car and determine in the inspection hole where the sound source is located.

To change the 2110 resonator, you will need to prepare two thirteenth keys in advance. If a neutralizer is present, first you need to get rid of the fastening that is adjacent to the structure. If it is missing, you can get rid of the front fasteners by disconnecting the exhaust pipe and the converter.

Typical exhaust system faults

Be sure to verify that there are any problems with the exhaust system before starting any repairs. And identify the node that has become unusable. Any breakdown reveals itself with the following signs:

Broken connecting pipes. As a result, the integrity of the entire system is compromised and exhaust gases are not properly purified.
Burnouts on the elements of the main muffler and resonator. This leads to the fact that the exhaust gases are not cleaned, and an extraneous sound appears when the engine is running.
Strong noises appear from the exhaust system and the main muffler, indicating that there is damage.

If small cracks appear in the VAZ-2110 exhaust system (8-valve injector), then in the early stages they can be healed using sealants. This measure will increase the service life of the elements slightly, by no more than one year.

How to determine whether a muffler is faulty

All original mechanisms on the VAZ 2110–2112 are adjusted at the factory to ensure a minimum noise level while driving. At the same time, engineers take into account not only the design of the engine itself, but also the car body. Therefore, after tuning the car, the noise level of the muffler increases sharply.

The main malfunctions of the muffler are those factors that interfere with its correct operation:

formation of holes in the body;

The use of such an element is unsafe for the driver

The most common problem with silencers on VAZ 2110–2112 can be considered the occurrence of knocking noises while driving. Even new and original products can cling to the bottom of the car and make loud noises:

Not long ago I received my license and became the proud owner of a VAZ 2112, I am satisfied with the car in all respects. A strange problem appeared: the muffler began to knock on the bumper or on the bottom of the car, it’s difficult to say for sure. I went to the service center and they looked at it and they really said the muffler was a little crooked, so they started bending it as a result? It was bent, drove about 20 km and the knocking appeared again, the interesting thing is that it doesn’t knock all the time, but at some moments, maybe when driving or while standing at a traffic light.

Problems with the operation of the device on the VAZ 2110–2112 can be determined visually. To do this, it is recommended to drive the car into a viewing hole or lift the rear of the body on a jack:

Inspect the entire exhaust system pipe. The presence of holes can be noticed immediately. In addition, rust spots will indicate that there is clearly damage inside the muffler housing.

Rock the mechanism with your hand - if it sways too much, then it’s time to change the fixation rubber bands and the reinforced gasket between the parts of the muffler.

After leaving the inspection hole, start the engine and sharply press the gas pedal several times - black exhaust smoke indicates severe burnout of the product.

Why do you need a gasket?

The gasket is an essential element between the main muffler and the resonator. Since all parts of the exhaust system become very hot, the gasket is made of heat-resistant materials.

If, when replacing a resonator or muffler, a gasket is not inserted between them, then the joint will not be as tight as possible. In addition, when driving on uneven roads, the two elements will rub against each other and quickly fail.

There is no need to worry about the procedure for replacing the gasket: it has a convenient shape and is placed on the element pipe with one movement of the hand:

Attach the gasket to the resonator flange.
Tighten 4 bolts.
Make sure the insert is kept level.
Tighten the bolts until they stop, without overtightening them.

Replacing rubber bands

The VAZ 2110–2112 muffler is attached to the bottom of the car with special rubber hangers. The elastic bands have minimal elasticity, so they can ensure reliable fixation of the mechanism. Usually two rubber bands are used - one is placed at the exhaust port, the other at the compartment with the resonator.

To change the suspension rubber bands, you need to place some kind of support (boards or bricks) under the device to fix its position at the maximum height. After this, the old rubber bands are removed. If necessary, the hooks on the bottom, on which new rubber bands are put on, can be cleaned of dirt and carbon deposits. After which the muffler is easily attached with hooks to the new rubber hangers. The suspensions are removed one by one from the front of the car to the rear.

How to remove the main muffler on a ten

As with most front-wheel drive models, replacing the exhaust system of the VAZ-2110 is quite simple. You do not need any special skills, extensive experience, or special tools.

But it is advisable to carry out all work on an inspection hole or overpass. The sequence of work is as follows:

The connection between the resonator and the muffler is made using flared pipes and an O-ring. This connection is crimped with a metal clamp, which consists of two halves and bolts.
First of all, dismantle the clamp; to do this, unscrew the nuts from the bolts using two 13mm wrenches and remove the O-ring. On cars of the tenth family, sealing rings made of graphite are used. Therefore, they do not stick to the surface of the pipe.
Remove the old main muffler from the rubber hangers.

Muffler VAZ 2110 - how to professionally replace it yourself

The exhaust system of any car constantly suffers from hot caustic gases, dust, dirt, moisture, impacts, and the VAZ 2110 muffler is no exception. Attempts to repair by applying welded “patches” to through holes help only for a short time, and therefore, you have to think about a major repair with replacement.

Muffler device for VAZ 2110

On the “ten” the entire exhaust system consists of separate components:

exhaust pipe (“pants”);
neutralizer;
Lambda probe;
additional muffler (resonator);
main muffler.

The most vulnerable and most often in need of repair are mufflers. It is not difficult even for a novice car enthusiast to understand the procedure for replacing these parts. Let's try to figure it out together how to gain experience in auto repair and save money.

Replacing the main muffler VAZ 2110

The main signs indicating the need to replace the muffler “can” are the appearance of pockets of through corrosion, fractures of the body and pipes, and severe deformation from impacts. Work should begin when the car is installed on the inspection hole. For a successful start and completion of the operation, a standard set of car keys and overalls is sufficient, since the bottom of the car is not the cleanest place.

Muffler 2110 is attached to the bottom of the car on brackets through hanging rubber bands, and to the resonator pipe by means of a bolted connection of two halves of clamps, tightening the flared ends.

Dismantling and installation of the device is carried out in the following sequence:

the bolts that tighten the clamp are unscrewed (often, due to severe corrosion, the bolts cannot be unscrewed and then they are cut off with a grinder. It is recommended to install a new clamp and bolts each time during repairs);
the graphite sealing ring is removed;
the muffler is removed from the suspension rubber bands;
if necessary, the rubber bands are replaced with new ones (experts recommend doing this);
the new muffler is suspended;
a graphite seal is installed at the junction of the pipes;
a clamp is put on, the parts of which are tightened with bolts.

Changing the resonator on the muffler of a VAZ 2110

The resonator can be replaced separately or together with the main muffler.

Since we have already considered replacing the main muffler, we will describe the installation and dismantling of only the additional muffler:

on the side of the main muffler, at the connection of the pipes, the bolts of the crimp clamp from two halves are unscrewed;
the sealing ring is removed;
from the neutralizer side, two spring-loaded bolts are untwisted, tightening parts of the floating flange;
the sealing ring is removed from the connection;
The additional muffler of the VAZ 2110 is removed from the rubber hangers, which are also removed from the mounts and inspected, and if necessary (if mechanical damage is detected in the form of cracks or tears) they are changed.

To install the muffler, you must carry out the described steps in reverse order, replacing the failed parts with new ones.

Necessary tips before replacing the neutralizer

The first along the exhaust gas path is the converter. It is he who is entrusted with the task of reducing the temperature and extinguishing the remains of unburnt fuel. This part is replaced using the same algorithm as for the muffler without any significant differences. One of the most discussed issues among car enthusiasts is the option of replacing the standard neutralizer with a flame arrester.

In this case, you need to think carefully and weigh the pros and cons. Why do you need such tuning? After all, an outwardly similar element has a different internal structure. It promises increased engine power and is ready to serve much longer. But this “medal” has two sides. The driver himself decides whether to conduct an experiment on his own car, since if you notice an increase in fuel consumption by 10-15%, then the flame arrester should be blamed for this.

Installing a new muffler

Assess the condition of the rubber hangers, which are located on different sides of the main muffler body. If they are overstretched or have cracks, be sure to replace them with new ones during installation.

The cost of these rubber bands is small, they are available in any store. Next you need to do the following:

Install the new main muffler onto the rubber hangers.
Insert a graphite O-ring between the pipe flares.
Place the clamp in place and tighten the nuts using 13mm wrenches.

At this point, the repair of the main muffler of the VAZ-2110 exhaust system (8 valves) is completed. Start the engine and check the muffler operation. There should be virtually no sound from the exhaust pipe. The motor will run clean and smooth.

What is a muffler resonator?

The resonator is a closed metal module with perforated partitions, the main function of which is to slow down the speed and reduce the pressure of the exhaust gases.

As a result, acoustic pollution of the surrounding space is reduced. The resonator chambers are offset relative to each other, which makes it possible to level out strong gas pulsations, increasing the service life of the exhaust system and the engine as a whole.

Causes and symptoms of VAZ 2112 resonator failure

The main reason for the failure of the resonator is a heavy load on the infrastructure from the inside (high temperatures and pressure) with the influence of external factors (moisture, reagents, cold, etc.) from the outside.

Being under such a double attack, this device often fails, which requires qualified repair work. A malfunction of the muffler resonator can be determined by the following symptoms:

increased noise when the engine is running;
metallic rattling in the corresponding section of the exhaust system;
reduction in engine power due to strong pulsation of exhaust gases

If you want to know how much it costs to replace a resonator, check out our price list published on this website. It is worth noting that repair work in this category can often be complicated by the presence of other exhaust system faults discovered during the preliminary diagnostics.

We are ready to eliminate any defects by purchasing the necessary parts ourselves. As a result, you will receive a car with a fully functional muffler, the characteristics of which correspond to the standard parameters.

How to remove the resonator

The resonator needs to be changed only after a new muffler has been installed. The sequence of work aimed at dismantling the device:

The resonator is secured using a crimp-type clamp and an O-ring.
The connection to the neutralizer is made using a floating flange, which consists of flared pipes and two bolts.
The fist is located on the opposite side of the resonator.

The work must be carried out on a cooled engine.

Quite often it is not possible to unscrew the bolts, so to make the work easier, you just need to cut them off using a grinder. Be sure to install new bolts during reassembly. If you don’t have a grinder at hand, then you need to use a penetrating lubricant, for example, WD-40. Apply this composition to all threaded connections, then wait 20-30 minutes.

Unscrew all the bolts and remove the clamps on the resonator. After this, you need to remove the old resonator from the rubber suspensions. Be sure to evaluate the condition of all rubber products. If they show signs of wear, install new ones during reassembly.

Resonator device

Structurally, the resonator consists of a perforated pipe (perforated along the entire length inside the device) placed in a metal box. The design also has a throttling hole, designed to increase the efficiency of damping wave vibrations in the pipeline. The internal cavity of the resonator is divided into two or more unequal parts by partitions located in a plane transverse to the pipe. In addition, most modern exhaust resonators have thermal and/or sound insulation (often of the same material) located under the shroud to reduce its temperature and/or noise emanating from the device.

Internal parts of the resonator

The internal cavities have an uneven volume to ensure periodic contraction and expansion of the exhaust gas flow, which in turn evens out its uneven pulsation. That is, each chamber has its own resonant frequency. In addition, they have a slight offset relative to the axis of the body. This is necessary to change the direction of exhaust gas flow. And internal perforation in the pipe is necessary to dampen high-amplitude sound waves created by gases.

Resonator installation

In the VAZ-2110 exhaust system (16-valve injector), work is performed in exactly the same way as on 8-valve engines. The procedure is as follows:

The new resonator must be mounted on rubber hangers and connected to the muffler. Moreover, it is necessary that the pipe from the resonator be strictly parallel to the ground.
If the neutralizer has wear, rust, or burrs, the connection must be lubricated with high-temperature sealant. This will ensure a high-quality connection of the exhaust system components.
Tighten the resonator and catalytic converter flanges using only new nuts and bolts.
The resonator is fastened to the neutralizer using two bolts and flanges. Moreover, the pipe is secured to the pants using a spring connection and flaring. An O-ring made of metal asbestos or graphite is installed inside.

This completes the replacement of the resonator; repairs present no difficulties. All work can be done independently, you just need an inspection hole or overpass.

Checking the resonator

Having identified the problems listed above, every car enthusiast should know how to check the resonator. This will not only normalize the operation of the engine and exhaust system, but will also increase the comfort of using the car, including for the people around it.

To check, you will need an inspection hole (if not, you can jack up the car). The diagnosis is made by visual examination. During the process, it is necessary to carefully inspect the integrity of both the device itself and the pipes connected to it (especially at their joints).

A clear sign of a problem is the formation of condensation in the cooling resonator, after which it begins to drip to the ground. This means that your body has lost its integrity and needs to be repaired, or rather replaced. You can check for condensation after some time, with the engine turned off (so that the resonator box cools down). Note! Some car enthusiasts, when making resonators on their own, specially drill a hole in the body to remove moisture. Therefore, if you bought a car with a similar resonator, then this test method will not suit you.

In addition, the integrity of the resonator body can be determined by the presence of exhaust gases escaping from it. This also indicates depressurization and the need to replace it. This fact can be checked with the car engine running by looking under the bottom. To be on the safe side, you can have a helper "turn off the gas" at the same time to get more exhaust gases through the system. Also, suspicion of depressurization is caused by the appearance of smoke under the bottom of the car while driving or when parked with the engine running.

How to remove the neutralizer

The VAZ-2110 exhaust system is standard for all cars. Almost the same design is used on nines, sevens, and even foreign cars. Even a motorist with very little experience can repair all elements of the system. If you have already decided to change the resonator and muffler, then it is also advisable to install a new neutralizer. The neutralizer is necessary to dampen the vibration coming from the car engine. This is a device that mechanically separates the muffler resonator and the exhaust pipe.

Replacement is carried out as follows:

If there is no damage to the springs and bolts, they can be reused. If there is wear, you need to purchase new elements.
The ring is replaced in any case, even if it is in almost perfect condition. If this ring begins to allow exhaust gases to pass through, damage to the flaring of the exhaust pipe and the converter will occur.
Unscrew all the bolts used to secure it. They must first be treated with a penetrating lubricant.

Exhaust system elements

In order to understand what the exhaust system on a VAZ-2112 is, you need to know all its elements:

Receiving pipe (they are also called “pants” - approx.).
Neutralizer.
Resonator (additional muffler - approx.).
Main muffler.

Exhaust system breakdowns

Among the possible breakdowns in the exhaust system, the following facts can be highlighted:

Mechanical damage to the exhaust system can be solved by welding these parts.
If one of the elements breaks, or a weld seam or tank burns out , it should be replaced only as a whole, since its restoration may not bring the desired results. And the only detail to which this fact cannot be attributed are metal expansion joints. They must be replaced independently of the entire exhaust system.
Since the cost of a new neutralizer in comparison with other parts is quite decent, many VAZ-2112 owners replace it with a flame arrester (stronger - approx.). In this case, the neutralizer is simply cut off, leaving only the flanges and a fist with flaring, after which the flame arrester is welded.
The cost of a flame arrester in comparison with a neutralizer is much less, but unlike its analogue, it does not burn out any remaining fuel. Please note that this fact can cause the muffler to fire and increase fuel consumption by 10-15 percent. Therefore, when installing it, pay attention to the presence of a lambda sensor (oxygen sensor - approx.). Passport data on fuel consumption for the VAZ-2112.

Installation of a new neutralizer

If you decide to modify your car, you can install the Stinger exhaust system on the VAZ-2110. It is more reliable and advanced than stock.

All work is carried out the same way. The neutralizer is installed as follows:

Install the neutralizer, and then put on the bolts. This must be done very carefully, making half a turn, no more.
When tightening, you must first tighten the bolts that secure the neutralizer to the resonator. The last to be tightened are the bolts securing the converter to the exhaust pipe.

Is a resonator needed?

Concept and principle of operation

What is a muffler resonator? It is one of the links in a car’s exhaust system. Structurally located in the middle part of the chain. Designed to extinguish exhaust gases and their temperature. Increased sound directly indicates defects in the system.

The entire system assembly, when functioning properly, dampens sound emissions from the exhaust manifold as completely as possible. In this way we hear whispering from the muffler. Although inside the system it is very, very hot, around 300°C, and all components are constantly in an aggressive environment.

Types of mufflers

Limiter: a fairly simple design that consists of a cylindrical pipe that enters the muffler body, tapering at the end, creating artificial pressure. The exhaust gases must overcome resistance and enter the muffler housing.

Physics says that a smaller hole creates more flow, reducing engine power. The scheme is far from ideal, but widespread.

Reflector: many holes are drilled directly into the muffler itself to level out waves and energy loss. A similar design is used in the manufacture of mufflers. Schematic design close to ideal. At the exit, the exhaust is almost inaudible.

Resonator: the design consists of a common body and 2 or 3 pipes with holes; passing gases create resonance among themselves, leveling waves and pressure. In this way, the ideal combination of pressure and resistance in the vehicle exhaust system is achieved.

Absorber: Similar to a resonator, but the tubes with holes are wrapped in material to absorb waves. Minimum absorption and maximum sound output of gases. In other words, direct flow.

As a rule, the muffler resonator is similar to the resonator design, and the “rear” muffler is a reflector or a combination of several (for tuning).

Reasons for failure

Metal fatigue, mechanical damage, corrosion. Humid weather, rain, snow, condensation, all this leaves an everyday imprint on the device, ultimately leading to its failure. Along the way, air helps, eventually forming a chemical reaction with the formation of acid. This is how we get a vile and unpleasant roar on the road.

In addition to the roar, there are other resonator malfunctions, such as:

A ringing and rattling sound, as a result of metal burning in the resonator body itself;
A drop in motor power due to the high resistance of gases to each other, as a result of which extinguishing does not occur and the outlet is clogged.

Repair

In most cases, they cannot be repaired. It is enough to purchase a new kit and install the system as a whole. It is not recommended to make replacements individually, since after a while the rest will burn out.

Some professionals manage to cut the seam with a gas cutter and weld it again, but no one can guarantee that the seal will be maintained. So we figured out what a muffler resonator is. It is up to each driver to decide which category to place oneself in: reckless driving with a roar or moderate ardor.

>Resonator

Any automobile mechanism in the working process creates a certain noise effect.

Removing the exhaust pipe

Most drivers call the exhaust pipe “pants”, since the element is very similar to this item of clothing. It is secured to the exhaust manifold using bronze nuts and studs. The trousers are attached to the neutralizer using a spring-loaded connection. There is a gasket between the exhaust manifold and the pants to prevent gases from leaking.

Dismantling the intake pipe is carried out as follows:

Using a 13mm wrench, you need to unscrew the nuts that secure it to the exhaust manifold. If there are metal plates with bent edges under the nuts, they must be bent. Please note that the connection uses studs that are screwed directly into the manifold.
If the stud is damaged, replacement is quite problematic. Therefore, it is necessary to carry out all work carefully to keep the threaded connection intact.
Be sure to allow the engine to cool before starting work, then apply penetrating lubricant to all threaded connections. With these simple steps, you won't have to use too much force, which will save your studs. If you break a pin, it will need to be drilled out. Before this, the exhaust manifold must be removed. Moreover, if you damage the exhaust manifold, replacing it will cost you a pretty penny. The cost of a new one is more than 2000 rubles.
After unscrewing all the nuts, it is necessary to move the exhaust pipe to the side and remove the gasket.
Unscrew the bolts that connect the exhaust pipe to the converter.

This completes the dismantling of the exhaust pipe of the VAZ-2110 exhaust system.

The exhaust system consists of an exhaust manifold, a exhaust pipe 3, an additional 5 and a main 7 muffler. The exhaust manifold and exhaust pipe mounting bracket 1 for 8-valve engines (2110 and 2111) are interchangeable with parts from Samara. The exhaust system of the 2112 engine is distinguished by an exhaust manifold and a downpipe.

On most cars equipped with an injection system, the exhaust pipe is equipped with an oxygen sensor (lambda probe). A three-component neutralizer is additionally installed in the exhaust system of these vehicles. Mufflers and neutralizer are non-separable units and when they fail, they must be replaced with new ones.

The exhaust manifold is cast from cast iron. A metal-reinforced heat-resistant gasket is installed between it and the cylinder head. The exhaust pipe is attached to the exhaust manifold on four studs (for the 2112 engine - on six). The connection is sealed with a heat-resistant gasket. The receiving pipe is made of stainless steel. It is attached to the power unit using a bracket with a clamp covering both outlet pipes.

The exhaust pipe is pivotally connected to the pipe flange of the additional muffler or neutralizer (for models where it is provided). Between the flanges there is a metal-graphite ring with a spherical outer surface. The inner surface of the flanges is also spherical, and they are tightened with spring-loaded bolts, which allows the muffler pipe to move (without losing its tightness) relative to the exhaust pipe when the power unit oscillates relative to the body.

To reduce noise and better thermal insulation of the body, the additional muffler has a protective cover. For vehicles with a neutralizer, an additional muffler is available with a shortened front pipe.

The neutralizer is designed to reduce emissions of carbon monoxide, nitrogen oxides and unburned hydrocarbons into the atmosphere. For this purpose, two ceramic blocks with many pores, coated with so-called afterburning catalysts: rhodium, palladium, platinum, are used. Passing through the pores of the neutralizer, carbon monoxide is converted into low-toxic carbon dioxide, and nitrogen oxides are reduced to harmless nitrogen. The degree of gas purification in a working neutralizer reaches 90-95%. For normal operation of the converter, the composition of the exhaust gases (in particular, the oxygen content in them) must be within strictly specified limits. This function is performed by the controller, determining the amount of fuel supplied depending on the readings of the oxygen sensor

The neutralizer and oxygen sensor are very sensitive to lead compounds - both of them are quickly “poisoned” and stop working, which, accordingly, leads to an increase in emissions of toxic substances. Therefore, if your car is equipped with a neutralizer, its operation, even short-term, on leaded gasoline is strictly prohibited. A faulty ignition system can also cause the neutralizer to fail. If sparking is missed, unburned fuel enters the converter, burns out and sinteres the ceramics, which can lead to complete blockage of the exhaust system and engine shutdown (or severe loss of power).

The main muffler is located after the additional muffler and is connected to it using an O-ring with clamps (as on the Samara). The mufflers are suspended from the body brackets on four rubber pads.

Installing a new exhaust pipe

All work is done in reverse order. But there are several features that you definitely need to know:

Install a new exhaust pipe.
A new gasket needs to be installed between the exhaust manifold and the pants.
Be sure to install a new O-ring between the neutralizer and the pants.
Tighten the nuts on the exhaust manifold studs. Tighten them evenly in a crisscross pattern.
Tighten the bolts that are on the spring-loaded connection to the converter.

This completes the repair of the exhaust system. The sound will be muffled as much as possible, the car will become almost silent. It is advisable to lubricate the new gasket with a CV joint type compound. This will improve the seal.

There is no need to worry; replacing a muffler on a VAZ 2110 is not at all a regular job that will have to be done systematically. Replacing the exhaust system is performed in several situations:

The muffler begins to make a loud noise;
Muffler elements burn out;
Connecting pipes break.

The sound of a burnt out muffler.

On a VAZ 2110, you can replace the muffler with your own hands, which will allow you to significantly save on the services of a service station.

The exhaust system of the VAZ 2110 includes a downpipe (pants), a neutralizer, a resonator and a main muffler.

Types of automotive resonators

When choosing an exhaust system resonator, you need to know what types they are and what materials they are made from. Currently, automotive resonators made of aluminized steel and stainless steel are popular. The former are distinguished by their low price but short service life. Its body is made of thin steel with a top layer of aluminum to prevent corrosion. However, this anti-corrosion composition is not durable. Therefore, we do not recommend that you purchase an aluminized steel exhaust resonator. It is better to buy a car resonator made of stainless steel. This material has a smoother surface (i.e. creates a minimum of turbulence in the system), and is also more stable when operating under extreme temperatures.

Replacing the muffler on a VAZ 2110

VAZ 2110 owners are quite lucky, since replacing the muffler is quite simple and does not require special skills or extensive experience. But you definitely need an inspection hole.

The replacement procedure sequence is as follows:

The muffler is connected to the resonator through an O-ring on the pipe flare. Plus, the connection is compressed with a clamp, which consists of two parts.
The clamp must be dismantled, so remove the ring. Since the O-rings used here are graphite, they should not stick to the metal.
Now the old muffler can be dismantled quite easily.
Be sure to check the condition of the suspension rubber bands located on different sides of the muffler body. They often end up stretched or covered with cracks. Rubber bands are quite cheap, so buy new ones and replace the old ones with them.
The new muffler is first mounted on rubber bands, after which it is inserted into the same new graphite sealing ring between the flares. Use a clamp to compress the connection. Ready!

It is also advisable to replace the resonator on a VAZ 2110. This is done after changing the muffler.

New resonator for VAZ 2110

The work of replacing the resonator is performed in the following sequence:

The resonator is secured to the muffler with a crimp clamp with an O-ring.
It is attached to the neutralizer using a floating flange consisting of two bolts and a flare.
On the opposite side of the element there is a so-called fist.
Removing bolts is often quite difficult. So that you don't have to suffer, just cut them off with a grinder and buy new bolts. This is the simplest solution to the problem.
If you couldn’t get a grinder, use a liquid key. This is a popular product among motorists - WD40 or its analogues. Treat the bolt attachment points with this compound, wait a while, after which the bolts should come off.
After removing the bolts, remove the muffler clamp.
Remove the resonator from the suspension rubber bands. Check the condition of the rubber bands. If they are worn out, replace them with new ones.
Take a new resonator, secure them to rubber and connect them to the muffler so that the pipe leading to the muffler from the resonator is parallel to the ground.
If you notice wear, burrs, or traces of rust on the neutralizer fist, be sure to coat the connection with sealant. Moreover, it must be a high-temperature sealant.
Armed with new bolts and nuts, tighten the catalytic converter and resonator flanges.
The neutralizer is fixed to the resonator with two bolts using a flange connection. The fastening occurs to the states, but there is a receiving pipe, using a spring-loaded connection and two flares. The space between them contains a sealing ring made of graphite or metal asbestos.

How does a resonator work?

Externally, the resonator is very similar to a muffler, which is why it is often called a small or additional muffler. This rather complex part consists of a large number of layers, with one of them performing its function.

Looking at the resonator in one section, it becomes obvious that it actually closely resembles a regular car muffler. In more detail:

The resonator design consists of several chambers separated by a special mesh, due to which there is a constant narrowing and expansion of gas flows, occurring in strong jerks. The resonator allows you to smooth out this pulsation, creating smooth flows.
By shifting these chambers, the direction of exhaust gas flow changes, which also helps smooth out uneven pulsations.
The exhaust frequency is also damped thanks to internal perforations. Allows you to reduce the volume of exhaust sounds.

Replacing the neutralizer

As you can see, the exhaust system of the VAZ 2110 car is designed quite standardly, its repair is not difficult even for a motorist with little experience.

When changing the muffler and resonator, it is likely that you may need to replace the converter. This operation is simple and can be done in a few steps.

The neutralizer serves to dampen vibrations from the engine and prevent them from occurring in the exhaust system of the domestically produced VAZ 2110 car.

If it needs to be replaced, it is done like this:

If the old springs and bolts are intact and have no obvious damage, you can continue to use them. They show characteristic signs of wear, be sure to buy new elements.
The ring should be replaced in any case, no matter how well the old one is preserved. If gases begin to leak through the old ring, this will lead to very rapid wear and damage to the converter flare and the exhaust pipe.
After installing the neutralizer, new bolts are put on, they are carefully but firmly tightened. Moreover, the first thing you need to do is tighten the bolts that secure the resonator.

DIY resonator

Before you design and assemble a resonator of your own design, you need to understand one simple thing. The thicker the material from which the exhaust system is made (including the resonator), the more effectively it will combat vibrations and pops. For this reason, the exhaust manifold, which first receives gases from the cylinder head, has such an impressive weight.

However, when choosing a material, you should not overdo it and choose too large blanks. Otherwise, the mass of the resonator will be significant, and this will affect the dynamic characteristics of the car and the load on its chassis.

There are a number of reasons why car owners make their own exhaust resonators. One of them is to reduce the noise that a standard factory muffler produces. Usually, for this purpose, an additional resonator is installed in the exhaust system. The second reason is the manufacture and installation of a direct-flow automotive resonator. Its characteristics are as follows:

reduction in engine power losses (really insignificant, about 5.10%);
changing the sound background of the engine and exhaust system (for lovers of low noise).

To make a direct resonator you will need:

a set of locksmith tools;
welding machine (it is advisable to use modern semi-automatic machines or inverters);
Angle grinder with a set of cutting and polishing discs.

The design of the resonator will differ depending on the materials used and the imagination of the car owner. We offer you one of the options for self-manufacturing a direct-flow automotive resonator:

Pre-prepare the pipe that will be the internal base of the resonator. It should be the same diameter or slightly larger than the factory one. Make sure that in the future it can be easily welded to the existing system, so do not choose a diameter that is too large (it is not yet possible to connect the pipe with a flange).
Then in this tube it is necessary to drill holes similar to the original resonator.
After this, you need to find a pipe of a slightly larger diameter (about 3.5 cm) that will serve as the outer shell. Its length must be reduced (according to the project, by an average of 5-10 cm on each side).
Make the necessary plugs to seal the housing at the ends. For this, sheet metal is used, where the outer diameters of large and small pipes are drawn. After this, the workpieces are cut out and processed by a grinding machine.
A pipe of larger diameter is placed in a pipe of smaller diameter, and the cavity between them is filled with glass wool (or better yet, modern mineral wool with good heat and sound insulation characteristics).
Next, you need to weld places along the edges of the pipe with large diameter finished plugs at the ends.
After welding, clean the seams with a grinder. After that you should paint them.
The last stage is welding a new resonator into the exhaust system of the car. Also clean welds after finishing work.

DIY resonator

This algorithm is approximate. There are a wide variety of options for homemade resonators. In some cases, they are simply removed from the system and a piece of pipe is installed in their place. However, we do not recommend that you do this, since you will not get a significant increase in the car’s power, but additional rumble from the exhaust pipe is guaranteed!

Additional problems

After installing a homemade resonator, the car owner will most likely be faced with a number of problems that need to be solved. First of all, we are talking about increasing the mass of the exhaust system, and, accordingly, the car as a whole. This is true if you used heavy metal objects to make the resonator. Therefore, a situation may arise where it is necessary to replace the supports and/or shock absorbers. That is, strengthen them. Otherwise, the car body will “sag” and the chassis will experience additional load.

Also, replacing the resonator implies changing the proportion of air entering the engine and the amount of exhaust gases. Therefore, it is necessary to empirically determine which optimal configuration to choose and make appropriate adjustments to the fuel supply and air filtration.

Replacing pants

Trousers

The exhaust pipe, also called pants (due to its appearance), is attached to the manifold using studs and nuts. Its fixation with the neutralizer is carried out by a spring-loaded connection.

Remove the exhaust pipe, paying special attention to its attachment to the manifold. Studs are used here, not bolts. They are screwed into the manifold, and connecting nuts are screwed onto them.
If the pin is damaged, it will be extremely difficult to replace it. Therefore, it is important to try to keep the old one intact and safe.
Treat the nuts with WD40, a product we all know. This will allow you to avoid using excessive force and keep the studs intact. If that doesn't work, the studs are drilled out. The process is complex, lengthy, and requires experience and skill.
There is a gasket between the manifold and the pants that needs to be replaced. Also install a new converter o-ring.
Now firmly press the exhaust pipe using the nuts. To do this you will need to compress the gasket.
Then tighten the bolts of the spring-loaded connection with the neutralizer of your VAZ 2110.

As you noticed, there is nothing complicated in this work. Each element is quite easily dismantled and a new one is installed in its place. Just be careful, act carefully and consistently. Plus, of course, do not forget about the importance of the quality of new parts. Buy only good spare parts that will ensure long-term and efficient service of the exhaust system on your VAZ 2110.

Malfunctions on VAZ cars of the tenth family

AvtoVAZ specialists conducted research, the results of which revealed that the car body, being a closed structure, has its own peak harmonics and can resonate at a certain frequency. To suppress spurious frequencies emitted by both the vehicle engine and those shielded by the body, it is necessary to use the range from 60 to 400 Hz, corresponding to medium and high engine speeds. A change in noise characteristics can be caused by making minimal changes to its design.

The most difficult noise to deal with is at low frequencies. From a technical point of view, it is impossible to combine tuning the exhaust system of a car and combating noise. You can maintain maximum power with a direct-flow muffler, and reduce the sound to a comfortable volume with a factory one.

Owners of VAZ 2110–2112 most often encounter breakdowns, burnouts and leaks in the exhaust system. Incorrectly set ignition, excessively rich mixture and pipe corrosion are the main causes of burnt out exhaust pipes. This defect is accompanied by knocks and pops, which indicate burnout of metal parts. A sign of burnout may be smoke from the exhaust pipe, indicating an overly enriched fuel mixture that is burning in the exhaust pipe.

The appearance of knocks on the body in the area where the muffler is located indicates mechanical defects in the part - changes in geometry, destruction of the rubber band, suspension or damper cushion. Eliminated by identifying the location of the breakdown and troubleshooting. Worn parts are replaced with new ones.

Muffler gaskets

The gas junction formed between the rear and additional mufflers is insulated using a rubber gasket or O-ring. In addition to the main function of closing the gap, it is also used to eliminate the movement of the pipes of the part relative to each other.

The appearance of carbon deposits under the bottom of the car at the joints of the exhaust pipe sections indicates damage to the gasket. Ruptures of the sealing ring are accompanied by the appearance of an unpleasant smell of exhaust gases in the vehicle interior and a sharp grinding noise that occurs during operation of the power unit.

Their replacement

A damaged exhaust system sealing ring cannot be restored - it can only be replaced with a new one. The gasket can be replaced manually in a few minutes.

The exhaust pipe flanges are secured with small bolts. Due to prolonged use, they can become covered with dirt and rust, which makes them difficult to unscrew. You can unscrew the bolts using a special tool or a grinder.
After unscrewing the bolts, the resonator tube is carefully retracted to the left.
The old O-ring is located on the resonator pipe. The rubber product is easily pryed off with a flat screwdriver and removed.
Carbon deposits are removed from the flanges with a wire brush and sandpaper.
A new O-ring is installed on the resonator tube flange. The exhaust pipe flanges are connected with a clamp, and the main muffler pipes are also connected to each other.

The cermet ring adjacent to the muffler gasket is fragile, and therefore when replacing the sealing ring, care must be taken so as not to destroy the ceramic.

Silencer - purpose, device, operation

An important element of the exhaust system is the muffler; operating a car without it is impossible. As a rule, the muffler is located at the rear of the vehicle and, in conjunction with the exhaust system, serves to remove harmful gases from the engine, bypassing the vehicle interior.

Car mufflers are made from stainless, aluminized and regular black steel. Stainless steel “silencers” are practically not available for sale due to their high cost and long service life (their service life is 10–15 years). Aluminized mufflers are installed on VAZ 2114/2115. They are common in the domestic and European markets (service life 3–7 years). Regular black steel mufflers are cheap substitutes and last only a few months, so are rarely used.

Burnouts in a small resonator

You can carry out the repair yourself. First of all, you need to remove the muffler resonator or other parts of the exhaust system. For simplicity and convenience of operations, such work should be carried out in a pit or on an overpass. This work can be both simple and labor-intensive, since many problems arise due to the fastenings of these parts: they were most susceptible to corrosion and stuck to each other. Experts recommend spraying the fasteners with a special liquid such as WD-40 before starting such work.

epoxy resin.

In practice, it has been proven that the use of such products gives maximum effect. A large number of these types of sealants and fiberglass fabrics are made from silicone materials; they can withstand high temperatures, some up to 1000 degrees. If you have carried out routine repairs using fiberglass, then it is advisable to start the engine after installing the resonator and warm it up for thirty minutes.

Removing and installing the catalyst

Removing and installing a catalytic converter on a VAZ 2115 is a relatively simple task. The procedure itself is carried out in several stages:

1. Using keys “17”, unscrew the fastening of the catalyst to the exhaust pipe of the exhaust manifold. We take out the bolts and spring washers;

2. Place a suitable stand under the catalyst. The fact is that the catalyst on the VAZ 2115 car is not fixed with the help of any rubber hangers, and therefore, in order for it not to fall on your head, after unscrewing the fastening bolts, it must be secured somehow. This can be done either by installing a stand under it, or by temporarily securing it with wire;

3. Now unscrew the catalyst from the inlet pipe of the additional muffler and carefully remove it.

We install the new catalyst in the reverse order.

How to repair a muffler

There are two ways to solve this problem. In the first case, you can buy a new muffler resonator. The price for it today is quite affordable. The cheapest option can cost about 500 rubles. But there are also mufflers that cost more than one thousand. At the same time, the choice of manufacturers and types of these system elements is quite large. If you follow the second path, you can also completely modernize the muffler resonator. In this case, it will be quite possible to carry out all the work on your own.

When repairing a muffler, it is necessary to take into account the design features of the element, select the appropriate material and maintain tightness.

Problems that arise with the resonator can be solved. To do this, you need to plan the work to be performed. If you have no experience in welding work, then invite a specialist.
