Description

The PPE High-Flow Exhaust Manifold and Up-Pipe Kit is a performance upgrade for 2001-2004 GM 6.6L Duramax engines. The manifolds are constructed from high-sil moly cast iron, while the up-pipes feature 304 stainless steel construction with aircraft-grade, internally sleeved bellows.

This system is designed to reduce exhaust back-pressure by over 20%, lower exhaust gas temperatures, and accelerate turbo spool-up. Each manifold includes pre-drilled and tapped 1/8” NPT bosses for EGT gauge sensors.
