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.
Features:
- 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 (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

Change in quality
Flavor Name: Bacon & Apple, Size: 5 Ounce (Pack of 1)
I have purchased these for a few years directly from Whole Foods, and was excited to see that it was now available from Amazon. The quality has been changing recently. I have these on AutoShip and they’ve gotten increasingly darker in color which I’m assuming means cooked more or longer and they’re incredibly hard now. These are supposed to be a soft chew and I have a Chihuahua and even cutting them up, he can barely eat them. Hoping this feedback gets back to the right people in quality control.
