BlackHeart LS Swap Exhaust Manifolds-Rear Dump-Natural Cast - 8505HKRFor 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" 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. Cast out of the same Hi Silicon Moly Ductile
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" 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. 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. This not only allows for the easy addition of catalytic converters but also makes it simple to connect to our many exhaust system options.
Features:
- 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
