It typically includes pipes, mufflers, resonators, catalytic converters, clamps, and hangers. The system reduces harmful emissions, minimizes noise, and directs hot exhaust gases safely away from the engine and cabin. Aftermarket kits may also improve performance and efficiency by optimizing exhaust flow.
