Hooker 8506HKR Blackheart Ls Swap Exhaust Manifolds - Rear Dump Sbc Exit - Natural Cast
Details

For applications or projects where our standard LS swap manifolds (8501HKR, 8502HKR, 8503HKR series) don't quite fit and our "center dump" manifold (8504HKR) exits too far forward, our new rear dump and rear dump SBC exit cast iron swap manifolds have arrived. These differ in that they exit in a straight-down fashion much like a block hugger header but exit more toward the rear of the engine than our "center dump" manifolds.

Specifications:

Description_ASC NOTE: Not compatible with 2004-2006 GTO starters/bellhousings. Breaking 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. HOOKER (TM) 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.

Description_FAB Similar to SBC manifolds (8525HKR) but for Gen III/IV LS engines - same exit centerline but raised up 1.36-inches (driver side) / tucked in tighter by 0.625-inches on (passenger side)
Description_FAB 2.5-inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
Description_FAB Tight tuck design that provides an exit between our standard swap manifolds and center dump manifolds (with passenger side SBC exit)
Description_FAB Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
Description_FAB Available in Natural as-cast finish for a factory appearance, silver ceramic, or black ceramic
Description_FAB Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
Description_FAB Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
Description_FAB Hardware included: Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware

Description_MKT For applications or projects where our standard LS swap manifolds (8501HKR, 8502HKR, 8503HKR series) don't quite fit and our "center dump" manifold (8504HKR) exits too far forward, our new rear dump and rear dump SBC exit cast iron swap manifolds have arrived. These differ in that they exit in a straight-down fashion much like a block hugger header but exit more toward the rear of the engine than our "center dump" manifolds.
Description_MKT While almost the same as our 8505HKR line, the 8506HKR line shares the same driver side manifold, but has the passenger side exit of traditional Small Block Chevrolet manifolds (see 8525HKR) to guarantee fitment and possibly bolt up your existing exhaust when doing an LS swap. Cast out of the same Hi-Silicon-Moly Ductile Iron as most of our other lines, it will be tough to find a more durable, streamlined, and quiet exhaust option. Available in natural cast, silver ceramic, or black ceramic finishes, these manifolds are offered with flanges, gaskets, and flange hardware for connecting to our lineup of adapter pipe kits or for ease in fabricating your own custom exhaust.
