The Hooker LS Cast Iron Exhaust Manifolds are offered in raw cast iron or four ceramic coating options, the cast iron construction will provide less under hood noise and years of leak free performance unlike tubular headers!
The short design is great for maximum ground clearance for vehicles that are lowered and the contoured design improves flow while directing the exhaust in a straight path at the exit port. The tight block hugging design also allows fitment in a wide variety of vehicles including engine swaps and OEM replacement when building a custom exhaust system!
Intended for all LS (except LS7 and LS9) engine swap applications where durability, quiet operation, emissions compliance and leak-free sealing is desired
Recommended for strong performance on engines making up to 500 horsepower (For optimum high rpm performance see Hooker long tube engine swap headers)
Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance - ideal for GM E-Rod installations
Free-flowing for good performance and catalytic converter efficiency
Cast from Hi-Silicon-Moly Ductile Iron to provide durability and corrosion resistance
2 bolt exit flange configuration matches 2010 Camaro (also the same as the E-rod exhaust manifolds) which can be used with OE gaskets and fasteners if desired, for an OE quality seal
304 stainless steel mating flanges included (mating flange fasteners are not included)
Perfect compliment to Hooker Headers LS Engine Swap Mount Plates and Holley GM LS Engine Retro-Fit Engine Oil Pan
