Discussing High Performance Exhaust Systems


Exhaust System – It is a piping that is used to guide the gases from the reaction exhaust away from the controlled combustion within an engine of stove. The whole system mostly transfers burnt gases from the engine to the exhaust pipe which may have single or double outlets. The pipe is carefully designed so as to carry toxic gases from the engine or machine. The pipe is also made of heat resistant material since the gases are extremely hot and can melt cheap material.

In most car or truck exhaust system, there is a manifold assembly that is designed to collect the gases from exhausts from two cylinders or more into the pipe. Often made of cast iron, it is made out of material saving design so as to use as little metal space as necessary and thus having the lowest production cost. Most inefficiency mostly occurs due to the combustion and nature of the engine and cylinder. Since most cylinders fire a different times, a different times their exhaust leave them so the pressure waves from the gas emerging from one cylinder may not completely leave the exhaust system.
