HOOKER BLACKHEART
HOOKER BLACKHEART LS SWAP EXHAUST MANIFOLDS – STAINLESS STEEL – POLISHED FINISH
Multi-fit – 2.50 in. Outlet – Gen III/Gen IV Chevrolet LS Engine
Part # 8503-1HKR
Hooker Blackheart now offers stainless steel versions of our popular cast iron lineup of LS swap exhaust manifolds based on the 8502HKR and family. The new stainless steel manifolds offer a number of advantages over the cast iron version, 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. These are available in both natural cast and polished depending on the look you’re going for and all hardware is included (gaskets, bolts, and flanges).
Features:
- 2.5 inch 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
- Polished finish, but also available in natural cast finish for a factory appearance
- Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included
- Stainless Steel construction to provide unmatched durability and corrosion resistance
- Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
