HOW IS EXHAUST GASES OUT?
To remove exhaust gases, a VAZ 2114 exhaust system was developed and installed, the diagram of which is shown in the figure.

It consists:
- Bracket for fastening the exhaust pipe;
- Sealing gasket;
- Clamp;
- Additional muffler;
- Rubber shock absorber;
- Central muffler;
- Rubber shock absorber;
- Clamp connecting pipes;
- Neutralizer;
- O-ring for the hinge;
- Oxygen sensor;
- Reception pipe.
Exhaust gases are removed as follows. From the exhaust manifold, exhaust gases enter a channel called the exhaust pipe, which directs them further into the converter. From its name it becomes clear that it is designed to burn the remaining flammable substances in the exhaust gases.
It primarily dampens exhaust noise and reduces turbulence. The next “obstacle to gases” is the muffler resonator, in which “acoustic mirrors” reduce the noise of escaping gases even more. And the last stage will be the central muffler. The exhaust system is manufactured and installed in such a way that gases are emitted outside the vehicle, which prevents them from entering the cabin.

HOW THE CENTRAL SILENCER IS SET UP
They are made of aluminized steel, stainless steel, ferrous metal and painted with powder coating. The installation of direct-flow sports mufflers is gaining popularity. The muffler structure can be seen in the figure.
Muffler
The VAZ 2114 muffler consists of:
- Metal body;
- Thermal insulating layer;
- Partition;
- Pipe with perforations;
- Calibrated hole (throttle);
- Front pipe with perforations;
- Inlet pipe;
- Partition in the middle part;
- Exhaust pipe;
- Partition in front of the muffler;
- Rear perforated pipe;
- Partition at the back;
- Metal body.
It should be noted that the exhaust system of the VAZ 2115 with a carburetor engine differs from the design described above. It does not provide for the installation of a neutralizer for exhaust gases.
What to choose?
Stinger Exhaust Systems
There are several options for muffling devices that can be used as a replacement for the old element on the VAZ 2114.
- From the factory, VAZ vehicles are equipped with an aluminum muffler, the service life of which is up to 6 years. Inexpensive, fairly reliable solution.
- More expensive variations made of heat-resistant stainless steel. They cost more than factory ones, but are distinguished by reliability and an extended service life of up to 10-15 years.
Unfortunately, it is not uncommon that replacing a given device does not give the expected result, because instead of the expected high-quality stainless steel element, buyers are faced with counterfeits. They are made from ordinary low grade black iron. The service life of such products is no more than a year.
To give the appearance of expensive products, low-quality mufflers are coated with special paints. Therefore, we recommend purchasing parts from trusted, certified auto parts stores.
ABOUT FACTORS AFFECTING THE SERVICE LIFE OF EXHAUST SYSTEM ELEMENTS
Elements of the exhaust system operate under the influence of mechanical, thermal and other types of loads.
The following factors have a strong influence on service life:
- Rapid heating to high temperatures, which can cause overheating of system elements;
- Frequent fluctuations in rapid heating and sudden cooling;
- The occurrence of vibration during operation of the power unit;
- Susceptibility to shock and mechanical damage;
- Pollution when driving in bad weather conditions;
- Getting scratches and chips from road surface particles;
- The occurrence of corrosion spots both inside and outside the exhaust system elements;
- Insufficient effectiveness of metal protection.
It is safe to say that for most of these factors, the timing of their manifestation is easily postponed to a later time. It’s worth changing your driving style, periodically cleaning the exhaust system from dirt, applying a protective coating yourself, and the problems will go away on their own.
Design
The name speaks volumes about the functions and tasks of this element.
- Reduce the noise produced by the piston system of the power unit.
- Discharge exhaust gases from the engine to a safe area, that is, outside the body. If this does not happen, gases will simply begin to enter the cabin.
The exhaust gas removal system includes several components:
- Reception pipe. This is a muffler element that is mounted to the engine using rigid mounting;
- Resonator. This is the first unit that receives sound vibrations and hot gases. Its design allows reducing the activity of turbulence, causing harmful particles to settle, thereby reducing the level of contamination of the gas flow that exits the combustion chamber;
- Muffler. The main part of the structure is a volumetric chamber made of metal. It is hermetically sealed, and inside there are divisions into separate sections. Passing through them, the gas is calmed and purified;
- Exhaust pipe. Removes gases outside the car body.
ABOUT SIGNS OF PROBLEM
As soon as there is even the slightest suspicion of problems with the exhaust tract, it is necessary to take measures to identify and eliminate these suspicions. Driving with a faulty muffler can cause problems from neighbors and traffic police.
You should be alert to the following manifestations in the operation of the exhaust system:
- The appearance of increased noise from a running motor;
- The presence of exhaust odors near the car, and in some cases in the cabin;
- The appearance of smoke from burnt-out exhaust elements under the bottom of the car;
There is no need to put off solving this problem. Take a few minutes to locate and determine the breakdown. After this, a decision is made to eliminate it. There can be only two options here: repairing the muffler or replacing the VAZ 2114 muffler.
Replacing the muffler on a VAZ 2114 with your own hands
As you know, a car includes several systems. But they are all connected into a single whole, which forces the machine to work in optimal mode. Loss of functionality of one of the systems leads to a chain of malfunctions.
Sports exhaust system for turbo
In order for the engine to always work as efficiently and efficiently as possible, the exhaust system must have excellent cross-country ability. A good exhaust gas output is of great importance for the VAZ 2114 and any other car.
If there is an obstacle in the way of combustion products exiting, the engine power may suffer, or it may stop working altogether.
The muffler plays an important role in the operation of the entire exhaust system.
REPAIR OR REPLACEMENT
Diagnostics has detected one or more small cracks in the resonator housing or main muffler. In this case, replacing them with new parts is not economically profitable. You can make repairs yourself. To do this, purchase a muffler repair kit: it includes rubber shock absorbers (the pipe is suspended on them) and clamps (for connecting the pipe joints). They can be purchased in several types.
VAZ 2114 mufflers can be repaired in the following ways:
- Buy any heat-resistant sealant and coat the burnout cracks with it, namely cracks, not large holes. The next step is to clean the body of dirt, paint and rust. After this, the cleaned area is degreased and a sealing layer is laid on the area to be repaired;
- Buy a repair kit with heat-resistant tape and binding wire. The part to be repaired is again prepared by analogy with the first method. After this, carefully wrap the body with tape and tie it with wire. The burnt area heals itself as the engine operates;
- Repair using cold welding. First of all, prepare cold welding for use. Next, you need to thoroughly clean and degrease the damaged area. After this, the damage can be repaired by welding (cold).
Of the methods described, the method using a repair kit received the most positive feedback.
For car owners who have access to electric welding, we can recommend this method of muffler repair. A patch of the required size is cut out of a sheet of metal 1.5-2 mm thick. Apply to the repair site and scald. Then the repair site needs to be treated with a protective compound. Good results are obtained by using semi-automatic welding in shielding gases.
Replacement
HOW TO REPLACE
Diagnostics showed that the repair will not give the expected effect, which means you need to change the VAZ 2114 muffler. This is quite easy to do if you have a new part. The replacement operation is carried out with your own hands in the garage or even just in the yard.
By any available means, access to the exhaust system elements is ensured. All bolted joints are processed using a wedge. If you don’t have one at hand, kerosene, brake fluids or oils will do. Prepare spare rubber cushions for suspension and tools in advance. You will need:
- Two open-end wrenches, socket wrenches or 13-socket heads:
- Metal brush;
- Small hammer.
Sometimes it is impossible to unscrew the bolts and they are cut off in an accessible way. Keep this in mind when preparing for work.
You can change the VAZ 2114 muffler like this:
- Unscrew the bolt on the connecting clamp and remove it along with the sealing gasket;
- Release it from the suspension, disconnect it from the resonator and remove it;
- When installing a new part, the gasket must be coated with sealant for exhaust systems and installed in the reverse order.
Lada 2114 › Logbook › Replacing the resonator
It turned out this is what it turned out to be. It’s not surprising that more smoke came out from under the car than from the chimney)
It was decided to change the resonator. I crawled under the car and was surprised to see the corrugation. She is a bellows, she is also a vibration compensator. I thought that the previous owner welded everything directly and would not be able to replace it himself.
I was sure that the resonator was unscrewed from the bottom and looked exactly like this:
But Google helped me find out that this is a Euro-3 resonator, which is screwed to the catalyst (which I don’t have). Therefore, you need to unscrew it here:
There is no overpass or hole, I raised the car higher and removed the protection
After suffering for several hours, I realized that I would still have to go to the service center. Rust, dirt and temperature took their toll. The key at 13 slipped, at 12 it was too small. If it was possible to turn the nut, it was only together with the bolt. Even the almighty VDshka didn’t help
I put on winter wheels and went to the car market
Resonator, gasket and clamp - 1480r
After waiting for my turn, I went into the box. The car was lifted and the car mechanic, swearing intricately, tried to remove the old resonator for about 40 minutes. He was rowing, hitting with a chisel, sawing with a circular saw. Finally, he succeeded) There were no problems installing the new one; they charged me 450 rubles for the work.
That's all, actually) I drove half the way home with the music turned off, listening to how quietly the car was running))
