Single and Dual Exhaust Systems

Single and Dual Exhaust Systems Points : Single and Dual Exhaust Systems A single exhaust system has one path for exhaust flow through the system. Typically, it has only one header pipe, main catalytic convener, muffler, and tailpipe, the most common type, it is used from the smallest four-cylinder engines on up to large V-8 engines.

A dual exhaust system has two separate exhaust paths to reduce back-pressure. It is two single exhaust systems combined into, one. A dual exhaust system is sometimes used on high performance cars with large V-6 or V-8 engines. It lets the engine “breath” better at high rpm.

A crossover pipe normally connects the right and left side header pipes to equalize backpressure in a dual system. This also increases engine power slightly.
