Hooker Headers
LS Cast Iron Exhaust Manifolds
GM LS (except LS7 & LS9) Exhaust Manifold – Black Ceramic Finish
PART #: 8501-3HKR
Hooker cast iron exhaust manifolds have been 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 at 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. “Hook” up your GM LS engine with Hooker cast iron Manifolds today!

Hooker Headers is proud to announce their new “Darkside” black ceramic coating process available on select header applications. This exclusive proprietary black ceramic coating offers the nostalgic look of the past as well as the aggressive look of a modern high-tech build. It also offers a more refined texture and appearance than is possible from painted finishes. With a satin sheen it has a unique look of its own and in addition to providing a more menacing look it also provides all the corrosion resistance of traditional silver ceramic.
