Allow your Diesel Engine to Breathe Easier for Performance Boosts

The factory up-pipe on your 2002-2004 Duramax 6.6L truck isn't anything to write home about, so we recommend replacing it with the premium PPE High-Flow Up-Pipe for an impressive increase in both power and performance. Up-pipes allow your diesel engine to breath easier and run more efficiently by greatly reducing the Exhaust Gas Temperatures which results in a boost of horsepower and torque. This particular system outflows your stock system by 53%, giving you more confidence whether you're challenging new terrain or passing somebody on the highway. This system works by reducing your rig's exhaust back-pressure to improve the overall flow of your exhaust system. This kit is perfect for anybody looking to make future modifications on their rig along with those who just need some improved engine performance.

Premium Construction & Installation Info

The PPE Passenger Side High Flow Up-Pipe was crafted to handle just about anything you throw at it. The up-pipe features 11-gauge 304 stainless steel construction that exhibits superior strength for all of the more extreme driving situations you and your truck get into. Internally sleeved elbows along with the pipe's .120" Wall tubing add an additional layer of durability to help resist metal fatigue from high temperatures and pressure fluctuation.
