Every car exhaust system has a muffler, and for many car enthusiasts its purpose is obvious. Driving around the city with a loud and toxic exhaust will be uncomfortable, and fines for exceeding the permissible noise level and harmful emissions from the operation of the car today are quite large. When operating VAZ cars, the muffler is often not given due attention, although it is useful to know how to correctly diagnose the degree of its wear. Timely replacement of the damper is mandatory, since its malfunction can pose a threat to human health and the operation of the car engine.
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.
What is a “glushak” for?
Main functions of the muffler:
- reduction of noise during fuel processing;
- reduction in the rate of gas release and their temperature.
The muffler is attached with special rubber pads to curved metal hooks, softening vibrations from the car exhaust
All elements of the exhaust system are exposed to high temperatures, so the coating (anti-corrosion paint, mastic) that is applied to the muffler burns out. The exhaust system of the VAZ 2114/2115 is mounted under the body on the bottom of the car.
An additional muffler or, in other words, a resonator is designed to eject burnt gas into the exhaust pipe and receive the next portion.
The resonator is an important part of the exhaust system; it directly affects engine power. The faster the exhaust gas is removed from the resonator, the faster and more power the car develops.
The design of the pipe consists of all the necessary elements, therefore, when exhausted, the exhaust gas is correctly distributed throughout the exhaust pipe
The muffler on the VAZ 2114/2115 is attached to the bottom of the car with special rubber bands, clinging to flat hooks on the side and top. Why is an elastic band used, and, say, not a metal fastener?
As exhaust gases pass through the exhaust pipe, vibrations intensify, the muffler begins to vibrate, and if the mount is solid-state, the vibration will be transmitted to the cabin. The rubber muffler mount softens vibrations and is therefore used on all cars.
For the VAZ 2114/2115, the muffler is a volumetric sealed metal chamber, divided inside by various partitions. The entire exhaust gas flow passes through the muffler sections and is finally extinguished and cleaned. If you look at the muffler diagram, it will look almost the same on all cars.
The principle of removing exhaust gases from a car muffler
Features of the catalytic converter
Catalysts began to be installed only on injection engines and with their help achieved more complete combustion of the mixture in the chamber. The VAZ 2114 catalyst consists of a housing, an oxygen sensor, a lambda probe, and a mesh made of special wire, which could help burn out the remaining fuel entering the exhaust system. At the inlet of the catalyst there is an oxygen sensor, which monitors the proportion of oxygen in the exhaust gases, comparing it with atmospheric pressure.
When gases entered the catalyst, the lambda probe assessed the composition of the gas and supplied information to the electronic control unit. The ECU, in turn, adjusted the composition of the mixture so that the content of harmful substances did not exceed the norm. This could go against the engine's requirements for achieving maximum power, but toxicity standards were put at the forefront. The only positive properties of the catalyst include slightly reduced fuel consumption. Although this indicator entirely depends on the condition of the catalyst. The scheme with one lambda probe complied with Euro 2 standards, but today this scheme is already outdated and is no longer used on new cars.
Replacing the muffler on a VAZ 2114/2115
Muffler failure on a car can happen for various reasons:
- mechanical damage;
- influence of atmospheric and mud precipitation;
- burnout of the internal elements and walls of the muffler.
Signs of a malfunction most often manifest themselves in increased exhaust sound: the car is very loud, rumbles, an abundance of exhaust gases appears from under the car in the muffler area and the smell of unrefined fuel.
How to change the "glushak" with your own hands
In many cases, the muffler cannot be repaired and requires urgent replacement. This is not as difficult to do as it seems. You will need:
- new muffler + repair kit (rubber cushions, corrugation, metal-graphite ring installed under a clamp at the junction of the pipes of the additional and main mufflers);
- tools;
- portable lamp;
- inspection hole or jack;
- two hours of free time;
- hands growing from the right place.
The repair kit consists of 5 rubber pads, two clamps and O-rings, a gasket
It is recommended to purchase replacement parts from trusted suppliers, as otherwise you may stumble upon a low-quality fake.
After purchasing parts, you need to make sure that they are actually suitable for replacement. You need to check all fasteners, holes and bends.
If all of the above corresponds to the parameters, you can begin dismantling the broken muffler. After installing the car on the inspection hole, check the condition of the fasteners and connecting bolts of the clamp between the additional muffler pipe and the main muffler pipe.
How to remove the muffler
It is recommended to dismantle the unit in the following sequence:
- Before unscrewing the nuts, treat the threads with WD-40 or rust remover and wait 10 minutes.
- Using a socket wrench or a 13mm socket, unscrew the two nuts holding the clamp.
- After removing the clamp, remove the sealing ring.
- Remove the rubber pads holding the muffler.
- Disconnect the muffler from the resonator.
If you have difficulty unscrewing the nuts, you can use a hammer and chisel. To do this, you need to rest the chisel against the edge of the nut and, with sharp blows of the hammer counterclockwise, try to “knock down” the thread. Otherwise, you should cut the bolts with a grinder.
Installing a new part
Installing a new muffler is done in the reverse order, but it is necessary to lubricate the gasket ring with high-temperature sealant. This will ensure a reliable and tight connection.

If there is no inspection hole, you can use a jack after placing a stop under the front wheels.
How to repair a “glushak” with your own hands
The muffler on the “fourteenth” and “fifteenth” is considered one of the most vulnerable points of the car. The fact is that due to exposure to high temperatures, the metal quickly burns out, that is, the tightness of the system is broken. Therefore, the part must be changed as soon as there is a suspicion that it is not working.
Reasons for failure
Most often, mufflers “burn out” - that is, due to hot exhaust, the metal inside the housing begins to thin out, which ultimately leads to the appearance of holes. However, this is not the only reason why the silencer may fail:
using a homemade device - handicraft products do not differ in quality and long service life;
mechanical shocks from uneven roads - dents and deformations of the pipe also lead to loss of tightness;
Rust and corrosion sooner or later affects even the highest quality original mufflers.
In general, all of these factors influence service life to some extent. The car owner can easily identify all of the above faults - just drive the VAZ into the inspection hole and visually examine the muffler. In addition, when deformations, burnouts and corrosion reach their “peak”, the part will begin to make characteristic sounds when moving - gurgling, sharp pops, knocking.
Why is the muffler knocking?
This part on the VAZ 2114/2115 can make knocking noises only in two cases:
it hits the body;
When moving, it touches the gas tank housing.
In any case, it is necessary to immediately take measures to eliminate this malfunction. Most often, the problem lies in severe wear of the rubber suspensions. It is enough to change them and the muffler will again return to its normal position under the bottom of the car.
Pendants are inexpensive, so you can buy new products without spending any money.
In some cases, the silencer begins to knock when its elements have been installed incorrectly - for example, after replacing the resonator or exhaust pipe. In this case, you will need to double-check that all fasteners and gaskets are installed correctly.

What to do if the plug is clogged
During vehicle operation, dirt, soot, fuel impurities and other sediments will inevitably accumulate in the exhaust system pipes. Gradually, they will settle on the walls of the muffler and clog its working space.
The driver can notice this only by the behavior of his car:
At first, it will be difficult to gain speed when overtaking.
Then, even with uniform movement, the car will have difficulty maintaining the set speed limit.
Black exhaust from the pipe, loss of engine dynamics.
Cleaning the muffler is a tedious and time-consuming procedure. In addition, if the pipes are clogged, then, most likely, after cleaning, other defects will be revealed - such as rust or burnouts. Therefore, it is more advisable to simply install a new one.

Thermal insulation is completely burnt out
The car owner needs to carefully ensure that the resonator coating is always sealed. The barrel is covered with special thermal insulation materials, which sooner or later burn out during the operation of the machine. If you do not change the insulation in time, you will soon have to change the muffler itself.
To do this, the pipes are dismantled from under the car and separated in parts. A special heat-resistant cloth is glued to the surface, which can be purchased at any auto store. Such protection will ensure a longer service life and significantly reduce the noise of the motor.
How to put a patch
Quite often, burnouts and holes appear on the muffler pipes. If the hole has not yet increased to a large diameter, it makes sense to weld it, that is, put a patch.
Having such extensive damage, the muffler can no longer be restored
This will require material identical to the pipe body and welding skills. Before applying the patch, you need to properly treat the edges of the pipe: remove rust, clean the body to bare metal and degrease the welding areas with a solvent.
The patch is applied to the hole (the patch must be at least twice the area of the hole) and tacked on several sides. After this, the weld can be applied. After the joint has cooled, you need to clean it of slag and paint the work area with heat-resistant paint.
Thus, all work on replacing and repairing the muffler can be done independently, without seeking help from specialists. The only difficulty can be caused by welding, since this will require both equipment and welder skills.
Repair of muffler VAZ 2114/2115
Before replacing the muffler, it is necessary to inspect it for damage. In some cases, you can get by with minor repairs and not spend money on buying a new part. Restoring the performance of the muffler is carried out according to the following algorithm:
- The muffler and weld seams are cleaned with emery cloth.
- The entire part is inspected for cracks, burns, and damage.
- If a defect is detected, use semi-automatic welding and weld the cracks. A metal plate with a thickness of at least 1.5 millimeters can be welded onto the burnout areas. Seal small cracks with high-temperature sealant.
All working areas must be sanded for a better result.
Welding is used if the muffler metal is strong enough. The seams are welded in a thick layer to avoid background and new burnout.

What's the result?
Taking into account the above information, it becomes clear that on the VAZ 2114 the exhaust system is not particularly complex in design. We also note that if you need to replace a VAZ 2114 muffler, the price of new system elements (both original and analogues) is at a completely acceptable level.
As for replacement and repair, all the work can be done with your own hands in a regular garage. If you have a welding machine and experience in performing welding work, then the entire system can be comprehensively repaired without the need to visit service stations or auto repair shops.
The main thing is that when choosing exhaust system parts (especially among analogues), you should pay attention and purchase only aluminized mufflers, which are the best solution in terms of quality and price. It is also advisable to study in advance the reviews of car enthusiasts for a particular brand and manufacturer before purchasing.
This will allow you to buy a muffler that is most durable in terms of service life.
Reasons for part failure
The muffler is affected by several different factors that can lead to failure, these are:
- Atmospheric precipitation, dirt. Precipitation means the occurrence of rain and snow. A mass that periodically falls on a hot pipe causes temperature changes, destroying the strength of the metal. Unfortunately, it will not be possible to protect the muffler in any way; moisture will in any case affect the metal. A smart solution would be to avoid driving through deep puddles and drive slowly on contaminated sections of the road. If the muffler and pipe are dirty, it is necessary to clean it with water (you can use a pressure jet from a hose). After cleaning, it is recommended to start the engine so that any water that has entered the muffler evaporates.
- Condensate. When the unit is idle for a long time, condensation forms in the muffler, causing a corrosive process. This leads to inevitable destruction of the internal parts of the muffler. This happens extremely rarely, but before the trip it is recommended to increase the operating speed by pressing the accelerator several times. The flow of exhaust gases removes moisture from the silencer.
- Chemical influence. As a result of the release of exhaust gas, a lot of toxic chemical particles settle on the walls of the muffler, destroying the metal, and allowing road reagents to get into the muffler.
- Physical influence. Hitting stones and blows from the muffler when driving on roads also lead to a lot of damage.
The chemical and physical effect on the muffler metal is a natural process. It will not be possible to disassemble and clean the muffler, since the container cannot be opened, and only the attention and professionalism of the driver on the road will help protect it from impacts and stones. Diagnosing and repairing minor damage at the initial stage will help avoid serious problems in the future.
The influence of various negative factors can lead to damage to the corrugation or other parts of the muffler
Algorithm
We must drive the car onto a viewing hole or a stationary overpass; We turn off the engine, squeeze the handbrake, wedge the wheels with boots or put it in first gear, you can choose any option; Let the exhaust system cool down a little, as it heats up under the influence of exhaust gases. You can easily burn your fingers. We always carry out all work wearing gloves. After making sure that the pipes have cooled down, using capes we unscrew the connecting clamps between the muffler and the resonator, otherwise known as the secondary muffler. From the rubber clamp-holder, remove the hook with which it secures the muffler to the bottom of the car; There will be an O-ring between the connections, be careful not to damage or lose it. Carry out visual diagnostics and replace with a new one if necessary. As a rule, the negative impact affects a short service life; Having removed the muffler, we put it aside so that it does not interfere with the process. We pre-lubricate the new ring with heat-resistant sealant, in this way we extend the service life; Install the system components in reverse order. After installation, be sure to start the engine and test the system
Pay attention to ensure that there are no gas leaks, otherwise your work will be down the drain. If everything is fine, you can continue on your way. If not, eliminate the shortcomings.
Schematically the exhaust system looks like this:
A flow of gases emerges from the combustion chamber through the exhaust manifold, exhaust pipe, neutralizer, resonator, and the muffler itself.
Burnout of the gasket can also be a weak point or “sore”
between the cylinder head and the exhaust manifold. Despite the tight pressure around the perimeter with the help of four stud bolts. The asbestos gasket still burns out, and the engine emits an unpleasant and loud sound.
Modern cars, including the VAZ 2115, use a neutralizer to significantly reduce emissions into the atmosphere, these are oxides of nitrogen, carbon, and hydrocarbons. Structurally, it consists of two parts with catalysts made of platinum and palladium. Passing through these plates, gases react, resulting in a low-toxic oxide, the harmfulness of which to the environment is minimal. According to experts, purification is about 85-95%.
Monitoring the performance of the neutralizer
carries out an oxygen sensor that scans the content of lead oxide in the gas environment. Cars equipped with such a device are strictly prohibited from using leaded fuel.
Faulty ignition or incorrect adjustment can cause premature failure of the converter. Unburnt gasoline coats the ceramic plates, which makes it difficult for gases to flow out and clogs the system. The first sign may be a sudden loss of engine power. Accordingly, repair or maintenance work is just around the corner.
This concludes the discussion of the topic, the exhaust system on the VAZ 2115 is over. Let's hope that our tips and recommendations will help many drivers gain experience and help them quickly find the source of the breakdown.
Exhaust system tuning
Currently, many motorists who prefer to use tuning to improve the technical characteristics of their cars are actively interested in installing direct-flow exhaust systems for the VAZ 2114. Thanks to the use of such an option, the power of the car’s power unit can be significantly increased. Installation of direct flow is a separate element of boosting a car engine.
The direct-flow process is based on the acceleration of the release of exhaust gases from the exhaust pipes in the absence of any significant resistance to their movement. By creating a vacuum in the exhaust system, the gases even more strongly draw new portions of exhaust from the engine combustion chamber, which, in turn, leads to an accelerated entry of new fuel into the cylinders.
Due to this increase in the speed of the process, the power of the power plant increases. At the same time, a direct-flow automobile muffler creates a resistance that is only 10% greater than the corresponding indicator of an exhaust unit that does not have a muffler at all.
For comparison: the same resistance value in a standard return flow muffler reaches 70%. By equipping the VAZ 2114 exhaust system with a special direct-flow muffler, you can increase engine power by 5-7%. Moreover, this is achieved even without changing the design of the fuel system, which requires a lot of money.
It should be borne in mind that additional reconstruction of the exhaust system cannot be taken lightly. If you decide to do tuning yourself, then only if you have the appropriate skills and practical experience. If there is none of this, it is better to seek help from specialists.
We continue to prepare for the summer season!
I couldn’t resist, I wanted to show some nice things) a little out of plan, but such chic things cannot be hidden)
I've been wanting a new exhaust system for a long time. The standard one has long since exhausted itself, the metal started ringing and there was a constant knocking on the bottom, in the area of the rear passengers, it seemed to be knocking on the beam. In short, I'm fed up with this standard. I bought all sorts of rubber bands and installed iron clamps instead of them, the knocking disappeared for a while, then appeared again. It’s all because of the suspension, the beam is too close to the pipe. Also, fastenings and so-called rubber donuts are not suitable, they are not provided for by the design))
The only solution was to change the entire system. The new exhaust system had to have the following qualities. Firstly, I don’t like forward flow with PROSport cans, it’s too loud, but there is NO SENSE! Secondly, there must be normal fastenings so that nothing knocks! -third, it should not stick out from under the bumper, IMHO KOLOKHOZ))
Well, the price should be acceptable for

OUR CENTERS ON THE CITY MAP
Do you want to inexpensively buy and replace a muffler resonator for a VAZ 2115? "MSK Silencer" - urgent replacement of Lada 2115 resonators with a 1-year warranty. 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 2115 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
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.
“Doctor Silencer” is a network of specialized service stations for professional replacement of VAZ 2115 resonators. Service stations are located in all districts of St. Petersburg.
Signs of a resonator malfunction: decreased engine power, unusual sounds (popping, ringing) under the body, the smell of exhaust gases in the cabin. It is possible to repair the resonator if the areas of damage (burnouts, cracks, corrosion) are small. But more often a faulty resonator has to be replaced.
