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.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntended for GM LS engine swap applications where durability and leak-free sealing is desired at a budget-oriented price\u003c\/li\u003e\n\u003cli\u003e304 stainless steel mating flanges included (mating flange fasteners are not included)\u003c\/li\u003e\n\u003cli\u003e2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold\u003c\/li\u003e\n\u003cli\u003e2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment.
