Crafted from high-sil moly, PPE High-Flow Manifolds offer robust performance. The Up-Pipe bellows, internally sleeved in aircraft-grade 304 stainless steel, feature an increased inner diameter for heightened flow. This exhaust system is meticulously designed to optimize power and flow characteristics, reduce exhaust gas temperatures (EGTs), and accelerate turbo spool-up. The result is enhanced power, improved fuel economy, and sustained reliability.
For added benefits, PPE offers a Ceramic-Coating option for the High-Flow Exhaust Manifolds. Originating from military and defense industries, ceramic coating is now a standard in high-performance applications like Formula 1 and military jet aircraft. This coating creates a thermal barrier, slowing heat absorption compared to raw metal. It improves flow, reduces EGTs, and provides lasting protection against corrosive elements. Opting for Ceramic Coating not only enhances performance but also ensures a long-lasting, visually appealing appearance for your PPE Manifolds, upgrading your GM 6.6L Duramax with a superior combination of durability and efficiency.
