2011-2016 GM 6.6L Duramax High-Flow Exhaust Manifold and Up-Pipe Kit

High-Flow Exhaust Manifold and Up-Pipe Kit for 2011-2016 (LML) GM 6.6L Duramax

PPE High-Flow Manifold is made from high-sil moly cast iron. 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.

High-Flow Exhaust Manifold

Ceramic coating is available as an option for High-Flow Exhaust Manifold.

Ceramic coating was pioneered by the military and defense industries. Now considered a standard in high-performance applications like Formula 1 and military jet aircraft. This same process is available to you - today.

The Ceramic-Coating option enhances the existing benefits of the PPE Manifold and Up-Pipe Kit which is specifically designed to maximize power and flow characteristics. Ceramic coating creates a thermal barrier and doesn’t absorb heat as quickly as raw metal. This reduces the thermal cycle and surface temperature. The ceramic coating promotes even greater flow, which means lower exhaust gas temperatures (EGTs). Ceramic coating also offers long-lasting protection against moisture, road salts, oil, fuel, and other corrosive chemicals. Plus, ceramic coating keeps your PPE Manifolds looking great - for a long, long time.

304 Stainless Steel Up-Pipe Kit
