Bifurcated exhaust: what is it and how to get it

Only a small part of car enthusiasts would like to have a loud sports exhaust on their car. The vast majority of drivers, on the contrary, are puzzled by the question of how to make a quiet muffler. Driving can be comfortable only if as little extraneous sounds as possible enter the cabin. The muffler creates its own background noise, which can be significantly reduced. The effect of this cannot be ignored.

Basic ways to make a muffler quieter

Before you begin upgrading your exhaust system, you should understand the nature of the increased exhaust sound. With each working stroke of the piston, a micro-explosion occurs in the combustion chamber of the engine cylinder, which is accompanied by a significant sharp expansion of gases. Naturally, a kind of blast wave, after it has done its job and moved the piston down, rushes through the exhaust system with the opening of the exhaust valve.

Thus, the nature of exhaust system noise is twofold:

• sound from expansion of gases;
• noise from vibration of exhaust system elements.

As you know, the main way to combat noise is to increase the weight of the elements. The thicker the metal, the less vibration and, accordingly, noise. That is why the exhaust manifold, which is the first to absorb hot gases from the cylinder head, is made so massive. Many car enthusiasts who had the opportunity to compare the weight of the exhaust pipe of a domestic car and a foreign one noted that the exhaust system parts of foreign cars are much heavier. This is why “our” cars are less comfortable in sound and noise comparisons.

Special elements are designed to reduce the speed of gas movement in the exhaust pipe: resonators and mufflers. First in line is the resonator. As soon as gases under pressure enter a part of the pipe with an increased volume, they immediately lose some of their energy and move further with less momentum. In the muffler labyrinth system, the exhaust gases finally lose their energy and are dissipated. A real quiet muffler on a foreign car is quite heavy and has several separate housings.

Making a quiet muffler with your own hands

When starting to modernize the exhaust system in order to reduce exhaust sound, you should be prepared technically and financially. For work you will need a full set of car mechanic tools. In addition, you will definitely need:

• welding machine (preferably semi-automatic or inverter);
• angle grinder with a set of discs;
• a workbench equipped with a vice.

One of the most affordable ways to get a quiet muffler in the average garage is to include an additional resonator in the existing exhaust system.

There are also two options for upgrading the exhaust system: installing an additional factory-made resonator in the area between the main resonator and the muffler, or making the device yourself.

What types are there?

If you are interested in how to make a double exhaust for a VAZ 2114, then you should think about choosing the product itself.

Today the market offers several types of products:

1. Resonator . They are created from high-quality perforated pipe, and it should be surrounded by a chamber. The latter is simply necessary to get rid of loud sounds. It is worth noting that in some cases several resonators are installed.
2. The standard option is that the product is a partition system. It is somewhat reminiscent of a labyrinth. It is the partitions that allow the emerging gas to be cooled. Passing through such a product, the noise subsides.
3. Direct-flow products, like others, are responsible for reducing noise. But in this case, the system is supplemented with special filters, fibers, which are installed in the middle of the pipe itself. The service life depends entirely on the wear and tear of these fibers and filters.

Double exhaust for VAZ 2114. Types and installation methods

Agree, cars that have a dual exhaust system always look very presentable and can indicate the sporting qualities of this vehicle. But what to do if you are the owner of a completely standard, popular VAZ car? The answer is obvious - install a double exhaust on the VAZ 2114.

Today we will look at the pros and cons, and directly touch on the replacement process itself.

Is a dual exhaust system necessary?

Before answering this question, let's look at history and figure out what's what. So, the need to install two exhaust manifolds has appeared since the invention of V-shaped engines, in which the cylinders are located at an angle. The result is one exhaust manifold for each side (line) of the cylinders. In other cases (with an in-line arrangement), one exhaust pipe is installed. The situation is a little different when car enthusiasts, in order to create decorative, visual improvements, make a branched one out of a single exhaust. This creates the impression that the engine has a dual exhaust system. In other words, tuning the exhaust system gives your car only external changes and does not affect the operation of the engine.

1. From a technological or design point of view, there is no need for installation.
2. From a tuning standpoint, this is an excellent, safe and inexpensive solution.

How to make a double exhaust on a VAZ 2114

If you decide to tune your iron horse, you may encounter the following questions:

• how to secure the additional pipe;
• how to properly distribute the exhaust;
• how to carry out the work correctly.

You should know that there are several most popular ways of making a dual exhaust: 1. By welding an additional pipe to the main one.2. By connecting an additional lead directly to the main resonator.

1. The first step is to remove the main muffler from the car.
2. Next, you need to make a decision about which design option to choose. We will bifurcate the exhaust, since with this design the gases will be distributed evenly both when the engine is running at idle speed and at higher speeds. We will make the branching on a section of pipe after the resonator, closer to the external gas outlet.
3. After the preparatory work, it is necessary to take a workpiece of the required diameter. At the same time, make sure that the metal product does not contain rust or mechanical damage. Take the necessary measurements (so that the pipe can be positioned on the spar as accurately as possible in the future). Using a welding machine, weld the workpiece to the main terminal. During the work, do not allow distortions; to do this, take measurements using a level, focusing on the position of the factory element. If distortions occur, smoke will not come out evenly.
4. After welding, the resulting structure must be secured under the bottom of the car. It is best to attach to the spar. To do this, you need to drill two technical holes in the connection area. For direct fastening, standard elements (metal bracket, rubber pad, metal ring) are perfect.
5. Carry out the remaining connections and welding work.
6. Start the engine and test the exhaust operation. Pay attention to the tightness of the resulting structure.

As a result, making a double exhaust for a VAZ 2114 yourself will save you a decent amount of money.

How to choose?

It’s worth figuring out how to choose the right double exhaust for a VAZ 2114; to do this, you can use the following tips:

1. It is necessary to take into account the sequence, the greater the weight of the product, the better. That is why the main attention should be paid to the choice of weight and quality of material.
2. It is also important to evaluate the quality of the seams; they should not be too thin, but they should be even.
3. The length of the product, as well as the attachment point to the body, needs to be assessed whether it is sufficient.
4. Evaluate how thoroughly the areas of the product are painted; if the paint chips, it is better to refuse the purchase. This is a sign that the product is susceptible to corrosion and will not last for a long time.

A thorough assessment of the build quality and reliability of the fasteners will save you from unpleasant surprises on the road in the future and guarantee a long service life of the exhaust.

It is quite enough to periodically inspect the elements, checking the reliability of fastening and the condition of the rubber hangers.

Accordingly, the service life of the pipes increases. Repairing a muffler is not always a justified undertaking.

Repairing a muffler is not always advisable. If a large burnout occurs, it is best to immediately replace the system element. In some cases, car owners weld holes or weld an additional layer of metal onto the thin walls of the muffler and resonator. However, this is a temporary measure, since the corrosion process is almost impossible to stop. On a number of modern models there is no corrugation. The corrugation really reduces the pulsation of exhaust gases, as it takes the main load on itself.

Thanks to the installation of this thermal protective element, the swinging of the exhaust pipe and suspension rubber bands can be minimized.

Accordingly, the service life of the pipes increases. The corrugation must be replaced after cracks and tears have formed on its surface. That is, the signal for replacement is the deformation of the product or its complete burnout.

How to do it yourself?

If you have enough time and materials, you can approach making the product yourself. But even in this situation, you will have to purchase the main parts of the exhaust system.

There are two creation options that experienced drivers know about:

1. The first option is to create an exhaust with different angles. So you just need to weld one pipe from the side into the pipe that runs from the manifold. At high speeds, exhaust gases will exit the pipes unevenly.
2. The second solution ensures the same amount of exhaust gases from both pipes. Two products are connected to the pipe that comes from the collector by welding, only the angles will be the same. This product looks more attractive.

Mitsubishi Lancer X muffler diagram

So, first, let's look at the exhaust system diagram. As you can see in the schematic diagram, the front exhaust pipe is connected to the exhaust manifold, and we take it as the beginning of the exhaust tract. Immediately after the front exhaust pipe, a catalyst is installed, the first lambda probe No. 1 is installed in it, then after the catalyst there is a central pipe, in which there is a built-in catalyst and lambda probe No. 2. This is followed by an additional muffler followed by a pipe to the main muffler.

The entire system has quite significant dimensions and would often be subject to shock loads if it were rigidly tied to any elements of the car, which is why it is suspended on special rubber mounts, and some connections are secured to each other through plastic connections - corrugations.

The main muffler is located at the rear of the car; it is a large “flattened rectangular can” connected to the central pipe by means of special bolts and springs. It is the main muffler that determines how loud the exhaust sounds.

The approximate dimensions of the main muffler are as follows: height - 135 mm, width - 270, length - 490. The diameter of the exhaust pipe varies depending on the modification of the car.

Lancer X with a 1.5 engine capacity has a central pipe of 48/49mm.

Lancer X with a 1.8/2.0 engine capacity has a central pipe of 55mm.

Therefore, when choosing any spare parts, you should focus on the modification of your particular car.

How is the finished product installed?

The simplest solution is to purchase one that is ready for installation. One product may be suitable for different models, so the same dual exhaust is suitable for 2109 and 2108, as well as for 2115 and 2114. This allows you to choose the ideal solution.

To install the exhaust you will definitely need:

• screwdriver;
• a set of keys;
• clamps;
• mounting brackets.

The installation procedure consists of several stages:

1. The old muffler is removed.
2. The right side of the new product is suspended, and it is necessary to use prepared pillows. Using a clamp and seals, the product is connected to the resonator.
3. Through the pipes, the main part is combined with the left part of the product.
4. Two holes are made in the spar using a drill; their diameter is approximately 1.5 millimeters. This will allow you to secure the holder in the future.
5. The holder and the cushion are connected, and a tapping rod is also inserted into the cushion.
6. On the opposite side, the product is secured using clamps and O-rings.
7. All that remains is to adjust and install the two nozzles symmetrically to each other. Having achieved an aesthetic appearance, you can consider the installation complete.

Split muffler, what to do

To replace the exhaust pipe ring, no special tools are required; all you need is a set of ratchet sockets.

To find the sealing ring, we find the exhaust manifold and go down to the first connection with the exhaust pipe, then unscrew the special bolts with springs and move the pipe down, simultaneously removing from it the ill-fated muffler gasket ring (part number 1775a085).

We replace it with a similar one and assemble it in reverse order. In addition, it is highly advisable to change the special bolts.
