Exhaust makes great influence on engine power. A good muffler must have a design that can provide an appropriate back pressure in order to produce optimum engine power. Hence, many vehicle owners are trying to replace the standard exhaust with an aftermarket or racing with the aim to get more powerful cars. Here are some exhaust tips I wanna share.
Replacing the muffler is actually the first step in performance modifications, but if it is wrong in choosing the exhaust pipe can not produce a greater engine power, but quite the opposite, the exhaust will be a barrier aka the car's speed power cars will be reduced from the standard state.
