This product is engineered to facilitate the installation of a later model, emissions friendly engine into a vintage / classic vehicle.

See Emissions Details
For applications or projects where our existing LS and LT swap manifolds don't quite fit or you need an exit point further forward in the engine bay to avoid the steering shaft, a starter, or some other component, our new "center dump" cast iron swap manifolds are the solution. Cast out of the same Hi-Silicon-Moly Ductile Iron as our 8502HKR and BHS516 lineup, 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.


  • 2.5 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • Tight tuck design that provides a more forward exit compared to our standard swap manifolds
  • Intended for GM LT engine swap applications where durability, quiet operation, and leak-free sealing is desired
  • Plain as-cast finish for a factory appearance
  • Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included
  • 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
  • Patent Pending Design

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.

The U.S. Environmental Protection Agency, the California Air Resources Board, Environment Canada, and other regulatory agencies prohibit the operation of vehicles on public roads that violate applicable emissions standards. The alteration of certified production vehicles to modify, remove, or render inoperable emissions control hardware or software, known as "tampering" is prohibited by the U.S. Clean Air Act and other laws. Tampering with motor vehicles emissions control systems is punishable by substantial monetary penalties.
