These cast iron exhaust manifolds Raw 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. 2.25" flanges
