The exhaust system of the car is very important.Its main purpose is the ventilation of cylinders. The exhaust gases in the exhaust stroke get into the exhaust manifold, and then they go into the intake pipe. Further on, the "smoke" path encounters a pair of resonators, and ends with such a "journey" by going out into the atmosphere through a silencer. Let's give some attention to its design. In fact, a silencer 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.
Often, manufacturers do not expect an exhaustsystem for maximum performance, then the tuners have to manufacture some parts, say, a silencer, with their own hands. What are the advantages of handicraft production before the factory? Let's consider them. The very first reason to build a silencer with your own hands is to increase its volume. In this case, the pressure of the gases at the output will drop substantially, which will result in a noticeable decrease in the noise level of the car as a whole. In addition, the pressure will drop in the system. Then the exhaust gases are easier to leave the cylinders, hence, the performance of the power unit is slightly increased.
The second reason to do thissilencer with your own hands, is the material of manufacture. As a rule, the main reason for the failure of the exhaust system is its burn-out, because the operating temperatures are very high. Conclusion: you need to choose a material of greater thickness.
How to make a muffler, you can findset of instructions. Each of them is almost universal. This is not surprising, because a silencer with your own hands can be made for one model and brand, and it will fit even a dozen of these. Here, in principle, the distinctions concern only the working volume of the engine, since a too small muffler simply will not cope with the volumes of gases passing through it.
In addition, the engine will be too noisy.From the above, it follows that there are quite a lot of reasons to make a silencer with your own hands. But do not think that this is a win-win option, thanks to which you will never again know the problems with the exhaust system, and the engine at once several times more priemiste and will not produce any sound. Everything has its drawbacks.
For example, technical inspection.With such a silencer, there may be problems with certification. If the noise levels of the work are not exceeded, everything will be in order. The design does not affect the toxicity of the exhaust. Particular attention should be paid to fasteners: they must be elastic, and also the "bucket" should not touch the bottom of the car. Also, do not forget about the fire safety, to ensure that there will be enough asbestos sheet laid between the muffler and the bottom.
