PPE Race High Flow Exhaust Manifolds with Up-pipes, GM (2001-15) 6.6L Duramax (Race Use Only)

PPE’s 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.
