PPE High-Flow Manifold Kit
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.
