Hooker 8505HKR Manifold, Exhaust, Ls Rear Dump, Raw

• 2.5-inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
• Tight tuck design that provides an exit between our standard swap manifolds and center dump manifolds (see pictures for diagram and specs)
• Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
• Available in Natural as-cast finish for a factory appearance, silver ceramic, or black ceramic
• Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
• Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
• Hardware included: Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware
• Similar to SBC driver side manifold (8525HKR) - same exit centerline but raised up 1.36-inches

NOTE: Not compatible with 2004-2006 GTO starters/bellhousingsBreaking in an engine with ceramic-coated versions of these manifolds will most likely result in damage to the coating and VOID all warranties providing coverage to it. HOOKERâ„¢ recommends using bare cast-iron manifolds or an old set of headers to break-in engines to avoid coating damage. Ceramic-coated manifolds require several heat cycles to fully cure before they will withstand extreme heat, so care should be taken to provide a series of 4 to 5 intermittent heat cycles to "set" the coating prior to putting the vehicle into service. An incremental increase in run duration and throttle angle should be added to each successive cycle; initial and final run durations between approximately 1 and 7 minutes will be sufficient to set the coating.
