EXHAUST SYSTEM / COMPONENTS
CPP Diesel has a comprehensive inventory of Duramax exhaust system components, so you can find everything you need to build up and modify your high-performance Duramax exhaust system. Upgraded exhaust systems improve the flow of air in your engine, allowing exhaust gas to escape, which frees up room for fuel and air burning, thereby increasing power.
