An invariable attribute of sports tuning is a direct-flow exhaust system. The widespread opinion in the circle of motorists that the installation of a direct flow increases the power of the engine is imposed by advertising and is erroneous. But the best way to verify or refute this statement is to equip your own car with a direct-flow exhaust system, and then compare the results.

- - carbon dioxide welding machine.
Instructions
Step 1
To reduce the cost of converting the exhaust gas system from the engine from a conventional to a straight-through - do it yourself. The purchase of ready-made solutions will cost the owner a tidy sum. But is it worth paying for the purchase of an expensive sound (similar to the operation of a sports car engine) in order to create the illusion of the presence of a “fancy car” next to them, which, apart from “roar”, is not capable of anything else?
Step 2
The same craftsmen who have nowhere to spend their own energy, and who want to make direct flow in their car at all costs, need to take into account some features of the direct-flow exhaust system during the conversion.
Step 3
A bit of theory. The purpose of any exhaust gas system is primarily to reduce engine noise. The car system under consideration consists of: an exhaust manifold, intake pipes, a resonator (a chamber with a perforated pipe) and a muffler with many baffles and perforated pipes inside.
Step 4
A straight-through muffler by its design resembles a resonator, in which the internal space between the body and the pipe with holes is filled with sound-absorbing material (for example, basalt wool). The service life of a straight-through muffler directly depends on the duration of the presence of mineral wool in its housing. Therefore, between the soundproofing and the pipe with holes, a fine-mesh mesh made of heat-resistant metal is placed to hold the filler.
Step 5
The sound of a running engine depends on: the size of the straight-through muffler, the quantity and quality of the sound-proof muffler that can withstand high temperatures, the material, the number and diameter of the holes in the inner pipe.
Step 6
Taking into account all of the above, you can proceed to the manufacture of direct flow. The costs of such a production will be mere pennies in comparison with the purchase of a ready-made kit.
