The factory manifolds and up pipes on the GM Duramax's have several design flaws that reduce potential exhaust flow. One of the larger draw backs is that the drivers side manifold has a large indentation in it for excessive clearance tolerances that is unnecessary.

Introducing high flow performance for your Duramax that is 50 state legal!
The factory manifolds and up-pipes on the GM Duramax's have several design flaws that reduce potential exhaust flow. One of the larger draw backs is that the drivers side manifold has a large indentation in it for excessive clearance tolerances that is unnecessary. Secondly, the factory up-pipes are weak and prone to warping when sustained heat is prevalent.
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! PPE's 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.
