Replacing your stock Manifold and Up-Pipes should be your first step in building a high performance exhaust system. These exhaust manifolds were co-designed by Honeywell (Garrett) and PPE using CAD software to maximize flow characteristics. The up-pipe bellows are high flow, internally sleeved and aircraft grade! Our High Flow Exhaust Manifolds and Up-Pipes lower Exhaust Gas Temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Perfect for applications with upgraded turbo systems and nitrous equipped trucks.
Features:- Cast hi-sil moly iron high flow manifold construction- Significant reduction in exhaust back pressure pressures- Free flowing Stainless Steel Inner Liner Bellows- Stainless Steel 11-gauge .120-inch wall diameter Up-Pipes - Built in bosses, pre-drilled and tapped 1/8” NPT for EGT gauge sensor- Substantial performance increase for upgraded turbo systems and/or nitrous injectionAvailable for: 2001-2010 Duramax 6.6LFactory manufacturing process leaves the Up-Pipe bellows’ inside liner significantly undersized and deformed causing excessive restriction. PPE’s bellows are larger in diameter by 37% providing increased flow.
