More info

A Performance Muffler, which is a vital part of your vehicle's exhaust system, is fitted to the exhaust pipe near the catalytic converter. Its function is to expel the exhaust gases as soon as possible while also dampening the engine noise. Standard mufflers have a smaller core for the exhaust gases to flow which results in a build up of back pressure. To overcome this, performance mufflers are designed with a larger core which improves the flow of exhaust gases. This minimizes the back pressure, thereby improving the engine performance.

Some types of performance mufflers are vector, spiral baffle and aero turbine. The vector muffler consists of concentric cones whereas the spiral baffle has a spiral-shaped baffle system. The aero turbine muffler produces partial vacuums to create negative back pressure.

A bad performance muffler is indicated by a reduced engine performance as the muffler fails to prevent the build up of the back pressure. A faulty performance muffler should be replaced to avoid compromising engine efficiency. At Buy Auto Parts we stock a wide variety of performance mufflers for every car make and model.
