Pacific Performance Engineering-11-16 GM LML 6.6L Duramax PPE High Flow Exhaust Manifolds With Up-Pipes

50 States Emissions Legal (E.O. D-701-34)

PPE High-Flow Manifolds are made from cast, high-sil moly. The PPE Up-Pipe bellows are internally-sleeved, made from aircraft-grade 304 stainless steel, and designed with increased inner diameter for higher flow. The entire Manifold and Up-Pipe exhaust system are designed to maximize power and flow characteristics, lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy, and maintaining reliability.

Features:

  • Significant reduction in exhaust back-pressure
  • Cast hi-sil moly iron high-flow manifold construction
  • Up-Pipes have free-flowing stainless steel inner liner bellows
  • Up-Pipes made from stainless steel 11-gauge .120-inch wall, with a 2-inch outside diameter
  • Built in bosses, pre-drilled and tapped 1/8” NPT for EGT gauge sensor

On 15-16 models minor modification to the upper shock mount is needed for installation.
