Hooker Blackheart LS swap exhaust manifolds provide stainless steel versions of their popular cast iron lineup of LS swap exhaust manifolds based on the 8502HKR family. The new stainless steel manifolds offer several advantages over the cast iron versions, including increased durability, reduced weight, and improved corrosion resistance. The shorty tight-tuck design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance. Available in both natural cast (factory look) and polished, Hooker Blackheart LS swap exhaust manifolds include all the necessary hardware (gaskets, bolts, and flanges).
More product features include:
• 2 1/2 in. outlet diameter offers improved flow for maximum performance from a cast exhaust manifold
• Tight-tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
• Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
• Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware
• Stainless Steel construction for unmatched durability and corrosion resistance
• Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
