HOOKER BLACKHEART
HOOKER BLACKHEART LS SWAP EXHAUST MANIFOLDS – NATURAL CAST FINISH
Multi-fit – 2.25 in. Outlet
Part # 8501HKR
These Hooker BlackHeart cast iron exhaust manifolds have a 2.25 inch outlet, natural cast finish and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Their contoured design aims the exhaust directly toward the exit port for improved flow. Being cast iron means they will provide years of leak-free performance with less under hood noise than traditional headers. Plus, their shorty design means you can route exhaust tubing close to your frame/floor pan for maximum ground clearance.
Features:
- Intended for GM LS 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 included (mating flange fasteners are not included)
- 2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
- 2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment. This allows the use of factory gaskets and fasteners if desired
- Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
- Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
- Perfect complement to Hooker engine swap mount plates and Holley engine swap oil pans
