Diesel engines need plenty of air to produce power and proper emissions. When you are pulling up a hill or accelerating, a high flow exhaust is critical for good engine performance. These kits are made from high quality stainless steel and include the chrome tip. The front head pipe is included with the kit.
The Duramax engine is a high speed diesel that needs to breath. Increasing the exhaust to a 4" mandrel bent system with a high flow muffler improves the turbo response. Quiet, there is a Duramax running.
High flow air filters are recommended to complete these performance kits.
