Rudy's Performance Parts is proud to announce the release of our new 304 stainless steel replacement up-pipes. These up-pipes are designed for use on your 2001-2004 GM 6.6L Duramax diesel truck. These up-pipes are designed to lower EGT's, reduce drive pressure and accelerate turbo spool-up time- all while maintaining reliability! This kit includes (2) up-pipe to turbo gaskets and (2) up-pipe to manifold gaskets. These are all the gaskets necessary to install these replacement up-pipes on your vehicle.

Duramax LB7 owners now have the ability of connecting the turbo and aftermarket down-pipe back exhaust system by removing the restrictive stock pipe. The Rudy's down pipe provides a smoother flow from the turbo resulting in lower EGT's and increased performance. The down pipe is a relatively easy install due to the precision bends that you've come to expect from Rudy's.
