An exhaust system is a series of pipes and components in a vehicle that directs exhaust gases away from the engine. It typically includes parts like the exhaust manifold, catalytic converter, and muffler. The primary purpose of the exhaust system is to reduce harmful emissions and noise produced by the engine. In addition to environmental benefits, an efficient exhaust system can improve engine performance. By allowing exhaust gases to exit quickly, it helps the engine breathe better, which can enhance power and fuel efficiency. Regular maintenance of the exhaust system is essential for optimal vehicle operation.
