Product Description

116112500 High Flow Exhaust Manifolds and Up-Pipes Kit – GM 6.6L Duramax 2017-2021 L5P.

PPE’s Manifolds and Up-Pipes are designed to maximize power and flow characteristics.

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 an increased inner diameter for higher flow. The entire Manifold and Up-Pipe exhaust system is designed to maximize power and flow characteristics, lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy, and maintain reliability.

Kit comes complete with two PPE Manifolds, two PPE Up-Pipes, a PPE Down Pipe Support Bracket, PPE 301 Stainless Steel Manifold Gaskets and Up-Pipe Gaskets.
