Replacing your stock exhaust manifold and up-pipes should be the first step in building a high performance exhaust system. Pacific Performance Engineering exhaust manifolds are co-designed by Honeywell (Garrett) and PPE, using CAD software to maximize flow characteristics. The included up-pipe bellows are high-flow, internally sleeved, and manufactured from 11-gauge, 0.120 in. wall aircraft-grade stainless steel with a 2 in. O.D. The exhaust manifolds are machined from high-silicon moly cast iron; feature built-in bosses; and are pre-drilled and tapped for a 1/8 in. NPT EGT sensor. PPE exhaust manifolds will help lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Order the model recommended for your application.

Pacific Performance Engineering GM 3.0L Duramax air-to-water intercooler kits add style and performance to your Duramax. The intercooler is 77 percent less restrictive than the stock GM model, featuring flow-optimized, cast aluminum end tanks and a 2.4 times larger, less restrictive core structure. These features along with their all-aluminum bar and plate-style construction and superior fin layout, PPE intercoolers deliver increased cooling with a cooler and denser charge air that also helps reduce exhaust gas temperature (EGTs), increases fuel efficiency, and lowers the pressure drop. PPE's Duramax air-to-water intercooler kits are completed with a diecast support bracket, a billet aluminum turbo adapter that replaces the turbo resonator, and PPE Performance silicone couplers and coolant hoses. They are available in several finishes. Choose the preferred color for your Duramax.
