Allow your Diesel Engine to Breathe Easier for Performance Boosts

The factory up-pipes on your 2001-2004 Duramax 6.6L truck aren't anything to write home about, so we recommend replacing them with the premium PPE High-Flow Up-Pipes 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 upgrade 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 Replacement High Flow Up-Pipes were crafted to handle just about anything you throw at it. The up-pipes feature 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. When it comes to installation, these up-pipes install directly in place of your stock components using the included hardware and instructions to make for a simple and straightforward process you can complete at home.
