Multi-fit - 2.50 in. Outlet - Gen III/Gen IV Chevrolet LS Engine

These Hooker BlackHeart cast iron exhaust manifolds have a 2.50 inch outlet, titanium ceramic 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.


  • Intended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired
  • Titanium ceramic coating for reduced engine compartment temps and improved corrosion resistance
  • Nickel plated steel mating flanges, MLS mating flange gaskets, and mating flange hardware included
  • Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
  • 2.5 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
  • 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
