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.
Great Products, Great Prices
We have a wide range of components that will suit your needs, and all of the parts we stock are high quality and manufactured by trusted companies. We carry tail pipes, downpipes, exhaust elbows and tips, mufflers, muffler deletes and tubing, splitters, exhaust adapters, clamps, and assorted accessories. Most of our parts ship out the day they are ordered if you order before 2:00 PM EST, so order early!
