Product Details

Product Name: Up Pipes
Manufacturer: PPE
Fitment Notes: GM Duramax

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.
