HIGH FLOW EXHAUST MANIFOLD AND UPPIPES KIT SILVERADO/SIERRA 6.6L LLY/LBZ BLAC

This High-Flow Exhaust Manifold and Up-Pipe Kit is designed for 2006-2007 (LBZ) GM 6.6L Duramax engines. The PPE High-Flow Manifold is constructed from high-sil moly cast iron. The Up-Pipe bellows feature internally sleeved, aircraft-grade 304 stainless steel, and an increased inner diameter for higher flow. The entire exhaust system is engineered to maximize power and flow, reduce exhaust gas temperatures (EGTs), and accelerate turbo spool-up, ultimately enhancing power, fuel economy, and reliability. This specific MPN, 116111620, includes a black ceramic coating, which provides a thermal barrier, reduces thermal cycling and surface temperature, promotes greater flow, and offers long-lasting protection against various corrosive elements.
