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.

Despite the fact that the exhaust system of the VAZ 2114 seems to be something of secondary importance, in fact the efficiency of its operation is no less important than the operation of the engine. It affects the performance of the vehicle and especially the operation of the fuel combustion system.

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.

How to tune the suspension of a VAZ 2114

For increased stability and good traction, the suspension should be installed and configured as rigidly as possible. This can be easily achieved using special low-soft shock absorbers. Also, do not forget about rigid stabilizers; they are installed to reduce the angle of inclination and stability in the transverse plane. Next, when tuning the VAZ 2114, we pay attention to the wheels. It is imperative to choose alloy wheels for the tires. And remember that without proper operation and careful treatment of your car, all the beauty will disappear at first.

About the VAZ exhaust system

The simplest exhaust system consists of just a manifold, an intake pipe and a resonator.
It is mounted not only on cars with a carburetor type engine, but also with an injection system (injector) without oxygen sensors. Such vehicles comply with Euro-0 and Russia-83 standards. Oxygen sensors with a catalyst (catal) are installed on cars with Euro-2 injection engines. In common parlance this system is called neutral or catcollector.

In VAZ cars, the catalyst can be of several types:

• an independent detail;
• combined with the receiving pipe;
• combined with a receiving pipe and a collector;
• combined with a resonator.

Models of VAZ-2108-2115 cars from the Lada Samara line are divided into the following types regarding engines:

• Euro-0 – carburetor and injector (from 1.1 to 1.5 l);
• Euro-2 injector (1.5 l);
• Euro-2 and Euro-3 – injector (1.6 l).

The latest, most current 8-valve Lada Samara models according to Euro-2 standards are equipped with a VAZ 181 catalytic collector - 1 sensor. Euro-3 standards stipulate the presence of 2 sensors, so you need a VAZ 183 model of catalytic collector. For 16-valve models - VAZ 186.

How to tune a VAZ 2114 engine

Now let's move on to the most important part of the car - the engine. Tuning it will increase power. For a person with an average knowledge of cars, this is quite simple to do; you just need to replace engine parts, taking exactly the same ones from a sports car. According to experienced modernizers who are professionally involved in tuning the VAZ 2115 and other cars in the series, such actions can increase the power under the hood by up to 15%.

If this is not enough for you, you can replace the cylinder head, as well as the system that is responsible for gas distribution and supply. Sophisticated fans of fast driving also change the gearbox. But this must be done based on the type and type of engine. And all that needs to be changed are the numbers of gears, the row and the most important gear. To complete the tuning of the VAZ 2114, you can also install a turbine.

Design

For each engine and car where this engine is used, an adapted gas exhaust system is created, which goes by the popular name - muffler.

Scheme

The name speaks volumes about the functions and tasks of this element.

1. Reduce the noise produced by the piston system of the power unit.
2. 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.

How to tune the interior of a VAZ 2114

Let's take a look inside the car. Here you can change first of all the glass. However, you shouldn’t bother with windshield tinting, otherwise there is a chance of getting fined and even having to part with the film. But darken the back and sides as much as you like. Also, for maximum comfort when driving fast, it is necessary to install sports seats instead of basic ones.

First of all, the feeling will change, because it will seem that you are sitting behind the wheel of a sports car, and not a “fourteenth”. In addition to convenience, you can add a little aesthetic beauty by replacing instrument panels, speedometers, installing a navigator, installing a sports steering wheel, and adding good acoustics.

Modification of the rear lights of the VAZ-2114

There are many options for modifying taillights. Here are a few of the most popular:

• individual LED elements;
• LED rings;
• LED inserts and overlays.

For individual elements of LEDs, LED strips or rings are used; for the body, reflectors of different sizes and corresponding colors are excellent, which can be purchased without much difficulty in automobile stores. The paint is also selected according to your taste and desire. In order to place the rings in separate cylinders, you can use tin cans, after carefully cutting out the desired size. If you decide to mount LED trims inside the headlights, then do not forget that they are mounted on top of the rear optics.

In any of the listed options, you cannot do without soldering iron skills. If you don’t have the skills, but want to modify the taillights, then it’s better to contact a tuning studio, where professionals will do all the work for you.

Negative factors affecting the gas outlet

Exhaust gas diagram

The gas exhaust system is located directly under the bottom of the car, which provokes a number of negative impacts.

1. Dust, dirt, and water regularly get onto the muffler body and hot pipe, which reduces strength.
2. Exposure to sudden temperature changes has a negative impact on the service life of the system.
3. Influence of external corrosion.
4. The negative impact of internal corrosion occurs due to condensation accumulating when the engine is idling.
5. The internal walls are destroyed due to the aggressive, pulsating influences of gas flows, abrasive and chemical particles that settle and destroy the material.
6. Elementary mechanical damage caused by vibrations and hits on the muffler by stones flying from under the wheels.

All these factors sometimes arise simultaneously, which is why the integrity of the element is at risk. It is not surprising that even the highest quality products in our road conditions last no more than 12 years.

Advantages of acoustic podiums

Podiums allow you to qualitatively improve acoustics, raising the sound to a new level. At the same time, you can not be limited to the standard landing dimensions of 13 cm, as provided by the manufacturer of the VAZ 2114. Among the many advantages of the podiums, I would like to separately highlight the following:

• Podiums allow you to install speakers (see How to choose speakers for a car radio yourself) in the car door. Thus, rear passengers no longer feel discomfort from strong sound, as was the case before. The sound will be evenly distributed throughout the cabin.

Podiums in the doors of VAZ 2114

• Podiums make it possible to create the correct direction of sound. As you know, sounds have a clearly defined direction. In other words, the higher the frequency of a sound, the more directional it becomes. This can explain the fact that the midrange and high-frequency speakers must be correctly directed.
• Podiums are always easy to install. Attaching them is quite simple and it is not necessary to cut through the metal of the door. Often acoustic podiums are firmly fixed to the skin.

Installing podiums is easy and simple

Note. You can evaluate the effect of “podium” sound immediately after fixing this element. Previously disturbing overtones will disappear, the transparency of the sound will improve, low bass will be added and the sound will seem to “get rid of” the speakers.

• Another advantage of the podium is the spaciousness of the “pocket” where a larger speaker can be inserted.
• Leather-wrapped podiums make it easy to remove dirt and dust.
• The podiums have petals on the base. This is also considered an advantage, since it will allow the element to be firmly fixed to the door.
• The podium will fit perfectly into the interior of the VAZ 2114, making the interior richer and more beautiful.

Replacement

If you realize that the muffler has already served its purpose and needs to be replaced, be sure to carry out a number of preparatory measures.

• Paying attention to the signs of breakdown that appear, check what exactly the fault is and where it occurred.
• Buy a new device to replace the old one. Be sure to make sure in the store that you bought a genuine product and not a fake.
• Buy new mounting pads made of rubber. Even if the old ones are in satisfactory condition. Under the influence of temperature and exhaust gases, rubber cushions quickly lose their characteristics. Therefore, it is not worth taking risks.
• Additionally, buy a metalgraphite ring. It is mounted at the place where the muffler pipe is connected, directly under the clamp. This is done to ensure better tightness.
• Having a complete repair kit is a very useful thing.

The preparation is complete, so you can start dismantling the old one and installing the new one:

1. Place the car in the pit;
2. Prepare for dismantling the clamp that connects the resonator and the muffler pipe. To do this, the two mounting bolts are cleaned with a wire brush, and the nuts are treated with the almighty WD40. If you don't have it, get some brake fluid or a rust remover. This is a problem area that makes removal difficult;
3. Using two 13mm wrenches, remove the two nuts that hold the clamp;
4. If all the manipulations carried out did not produce results, the fasteners will have to be cut off with a grinder. It is not difficult. Replace the clamp with a new one, of course;
5. After dismantling the clamp, remove the o-ring made of metal;
6. Disconnect the muffler pipe from the resonator;
7. Now you can easily remove the muffler itself;
8. Installation of a new exhaust system element is carried out in the reverse order;
9. Be sure to lubricate the gasket ring. Moreover, it must be a special sealant for exhaust gases. This way the tightness of the connection will be at the maximum level.

Making podiums for acoustics

VAZ 2114 acoustic podium and its production

Let's look at how to make podiums for doors. As a rule, the standard places on the doors of a VAZ 2114 car are designed to install speakers measuring 13 cm. What should we do if we want to install larger speakers? The most suitable material from which to make good podiums is plywood. And to start the process, you need to cut out circles of a certain size from plywood for the speakers you intend to install.

Advice. When cutting, we recommend using an electric jigsaw. It will save both time and nerves. In extreme cases, you can use a drill.

To adjust the podium to the desired shape, the following materials are used:

And now everything is in order.

Frame making

Note. To make the frame, it is recommended to use plywood, the thickness of which does not exceed 5-6 mm.

• We cut out the rings with a jigsaw so that the purchased speaker sits tightly in it.
• Using spacers from bars or self-tapping screws, we create a suitable frame where the speaker will be placed.

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.
