These Flowtech cast iron exhaust manifolds have a 2.25 inch outlet, natural cast finish and are designed to hug close to the engine block so they fit into a wide variety of replacement and engine-swap applications at a budget friendly price. 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.
