Part Details Vehicle Fitment Reviews
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 manifoldTight 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 desiredAvailable in Natural as-cast finish for a factory appearance, silver ceramic, or black ceramicCast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistancePerfect complement to Hooker engine swap mount plates and Holley engine swap oil pansHardware included: Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardwareSimilar to SBC driver side manifold (8525HKR) - same exit centerline but raised up 1.36-inches

Emissions

This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle. Federal guidelines indicate that an engine swap is allowable if one or more of the following conditions apply:

  • If there is a reasonable basis for knowing that emissions are not adversely affected as described in the EPA Tampering Policy dated November 23rd, 2020
  • The resulting vehicle is identical (with regard to all emissions related parts, engine design parameters and engine calibrations) to a certified configuration of the same or newer model year as the vehicle chassis
  • The vehicle is a uncontrolled vehicle - Vehicles that were manufactured before emission control regulations took effect are called uncontrolled vehicles. Aftermarket parts regulations and anti-tampering laws do not apply to these vehicles
  • An EO legal engine swap kit is utilized (such as a GM EROD)
  • The vehicle is being used for Competition Use Only - Racing Use Only Vehicles are vehicles that are used exclusively for competition that are not registered and that may never be used on the street

Consumers are responsible for complying with laws prohibiting tampering, and for ensuring that modified vehicles are operated in a manner that complies with applicable laws.
