Maximizes Flow and Power
PPE's High-Flow Manifolds are 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 and accelerate turbo spool-up while increasing power, fuel economy, and maintaining reliability.
Heavy Duty Components with Ceramic Coating
PPE's High-Flow Manifolds is constructed of heavy-duty cast, high-sil moly the Up-Pipes is constructed of heavy-duty aircraft-grade 304 stainless steel. Finished with a durable silver ceramic coating to enable maximum power and flow characteristics. The Cermaic coating creates a thermal barrier without absorbing heat as quickly as raw metal. The ceramic coating also creates greater flow for a decrease in EGTs. The ceramic coating also protects against moisture, road salts, oil fuel and other corrosive chemicals, ensuring your PPE Manifolds look their best for a long time.
Fits: 2007.5-2010 GM 6.6L Duramax
