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.

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
