Compound Turbo (Round-Pipe) Race High-Flow Exhaust Manifolds with Up-Pipes - GM 6.6L Duramax 2001-2016

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 304 stainless steel with an increased inner diameter.

The entire Manifold and Up-Pipe exhaust system is designed to lower exhaust gas temperatures, reduce turbo drive pressure and accelerate turbo spool-up while increasing power, fuel economy and maintaining reliability.

NOTE: Race version PPE Manifolds and Up-Pipe Kits will not fit any Duramax engine that requires a down pipe
