2001-2004 GM Duramax 6.6L, Race Manifolds & Up-pipes, High Flow, Cast Hi Sil Moly, Stainless Steel,

PPEs Manifold and Up-Pipes are designed to maximize power and flow characteristics. The Up-Pipe bellows are high flow, internally sleeved and aircraft grade with an increased inner diameter which all together increases flow by over 20%. The entire Manifold and Up-Pipe exhaust system is designed to lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Designed for closed course racing vehicles not to be used on the street.


Significant reduction in exhaust back-pressure
Cast hi-sil moly iron high-flow manifold construction
Up-Pipes have free-flowing stainless steel inner liner bellows
Up-Pipes made from stainless steel 11-gauge .120-inch wall, with a 2-inch outside diameter
Built in bosses, pre-drilled and tapped 1/8” NPT for EGT gauge sensor
Kit includes driver and passenger Manifolds, Manifold bolts, Up-Pipes, gaskets and down pipe support bracket

Factory manufacturing process leaves the Up-Pipe bellows inside liner significantly undersized and deformed causing excessive restriction. PPEs bellows are larger in diameter by 37% providing increased flow.
