HIGH FLOW EXHAUST MANIFOLD AND UPPIPES KIT SILVERADO/SIERRA 6.6L L5P SILVER

High-flow, silver ceramic-coated exhaust manifold and up-pipe kit for GM 6.6L Duramax L5P engines. Replaces restrictive factory components with high-silicon molybdenum ductile iron manifolds and internally sleeved 304 stainless steel up-pipes. The silver ceramic coating provides thermal insulation, reduces EGTs, improves efficiency, and offers corrosion protection. Engineered for increased power, throttle response, fuel efficiency, and faster turbo spool-up. Direct-fit design includes gaskets, ARP 12-point fasteners, and assembly lube. Up-pipe hardware sold separately. 50-state emissions legal (CARB EO Number D-701-34).
