PPE High-Flow Exhaust Manifold and Up-Pipe Kit for Chevy/GMC (2017-26) 6.6L Duramax (Black Ceramic Coating)

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 Manifold looking great - for a long, long time.

304 Stainless Steel Up-Pipe Kit
Choose the Ceramic Coating Option added to your PPE Manifold and upgrade your GM 6.6L Duramax with the superior combination of PPE Manifold with 304 Stainless Steel Up-Pipe Kit.

Complete your upgrade with a PPE 3-Inch 304 Stainless Steel Down Pipe.
