PPE’s Manifolds and Up-Pipes are designed to maximize power and flow characteristics.
The 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 lower exhaust gas temperatures (EGTs) and accelerate turbo spool-up while increasing power, fuel economy and maintaining 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.
Ceramic-Coated Manifolds option available for the High-Flow Exhaust Manifolds and Up-Pipes Kits - GM 6.6L Duramax
Ceramic coating was pioneered by 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 known benefits of the PPE Manifolds and Up-Pipes Kit which is designed to maximize power and flow characteristics. The 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 Manifolds and Up-Pipes system is designed to lower exhaust gas temperatures (EGTs), accelerate turbo spool-up while increasing power, fuel economy and reliability.
Ceramic coating creates a thermal barrier so it doesn’t absorb heat as quickly as raw metal. This reduces the thermal cycle and surface temperature. Ceramic coating promotes 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.
Choose the Ceramic Coating Option and upgrade your Duramax with the superior combination of PPE Ceramic Coated Manifolds with 304 Stainless Steel Up-Pipes Kit.
