    The Hooker LS Cast Iron Exhaust Manifolds are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications. Offered in raw cast iron or four separate ceramic coating options, the cast iron construction will provide less underhood noise and years of leak-free performance to come.The short design is ideal for maximum ground clearance and a contoured design improves flow while directing the exhaust in a straight path at the exit port.

    Features:

    • 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
    • 2.25" or 2.5" outlet flanges available
    • 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
    • Available in plain as-cast finish or with ceramic coating for reduced engine compartment temps and improved corrosion resistance
    • Can be installed reversed for use as a custom turbo manifold application
    • Not compatible with 2004-2006 GTO starters/bellhousings
    • Although designed as a stock replacement, this product does not have a C.A.R.B. Executive Order Exemption and therefore may or may not be legal for any particular pollution controlled application
    • Check with your state or local governmental authority regarding approval for your application
    • Have been validated thus far for fitment on 1970-81 GM F-bodies, 82-88 GM G-bodies and 68-72 GM A-bodies

    Iam doing a ls swap on 1972 chevy blazer 4x4. Will these fit without hitting frame?

    Asked by: TWP1
    This will work as manifolds on your truck.
    Answered by: Dean R
    Date published: 2018-02-16

    I have 2.5" between the block and steering u joint on my 5.3 ls. How far out will these manifolds stick out from the block? I need headers or manifolds that are as close to the block as possible. Any recommendations?

    Asked by: Kluger
    No, this will be at least 3" away from the engine possible a little more. some headers may work, you can call our tech line 1-800-345-4545 for more assistance.
