Hooker Exhaust Manifolds 8502-1HKR

Overview

Hooker's popular LS exhaust manifolds are now available with a 2.5-inch diameter outlet for improved flow. These 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.
