How to make a muffler with your own hands

The exhaust system of a car is very important. Its main purpose is cylinder ventilation. Exhaust gases in the exhaust stroke enter the exhaust manifold, after which they follow into the exhaust pipe. Further on the path of the "smoke" a pair of resonators is encountered, and such a "journey" ends with an exit into the atmosphere through a muffler. Let's pay a little attention to its design. In fact, a muffler is a tin can with various partitions inside. They form a kind of labyrinth, passing through which the gases cool down, lose speed and somewhat decrease in volume.

Manufacturers often do not calculate the exhaust system for maximum performance, then the tuners have to make some parts, say, a muffler, with their own hands. What are the advantages of handicraft production over factory production? Let's take a look at them. The very first reason to make a muffler with your own hands is to increase its volume. In this case, the pressure of the gases at the outlet will drop significantly, which will entail a noticeable decrease in the noise level of the car as a whole. In addition, the pressure will drop in the system. Thenit is easier for exhaust gases to exit the cylinders, therefore, the performance of the power unit increases slightly.

The second reason why you should make a muffler with your own hands is the material of manufacture. As a rule, the main reason for the failure of the exhaust system is its burnout, because the operating temperatures are very high. Conclusion: you need to choose a material of greater thickness.

It can be a pipe or sheet metal. Naturally, it is worth remembering the weight of the product. Such a homemade muffler can last much longer than a regular one. In addition, you can change the geometry of the baffles inside, which will also have a positive effect on the performance of the entire system and exhaust noise.

There are many instructions on how to make a silencer. Each of them is almost universal. This is not surprising, because a do-it-yourself muffler can be made for one model and brand, and it will fit another dozen of these. Here, in principle, the distinctions concern only the displacement of the engine, since a muffler that is too small simply will not cope with the volumes of gases passing through it.

Also, the engine will be too noisy. From the foregoing, it follows that there are quite a few reasons to make a muffler with your own hands. But do not think that this is a win-win option, thanks to which you will never know problems with the exhaust system again, and the engine will immediately become several times more responsive and will notwhile making no sound. Everything has its drawbacks.

For example, inspection. With such a silencer, certification problems may arise. If the noise level of the work is not exceeded, then everything will be in order. The design does not affect the toxicity of the exhaust at all. Particular attention should be paid to the fasteners: they must be elastic, and the “backcloth” itself should not touch the bottom of the car. Also, do not forget about fire safety, to ensure which it will be enough to have an asbestos sheet laid between the muffler and the bottom.
