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.

    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.

  • 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)
  • 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 (with passenger side SBC exit)
  • 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
