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! The PPE high flow exhaust manifolds and up-pipes lower EGTs, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Perfect for upgraded turbo systems and nitrous equipped trucks with high EGTs. Also improves performance and fuel economy of engines with upgraded air/fuel systems.

Factory 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.
