Their contoured design aims the exhaust directly toward 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.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntended for GM LS engine swap applications where durability, quiet operation, and leak-free sealing is desired\u003c\/li\u003e\n\u003cli\u003eTight Tuck Design Provides Universal Fit\u003c\/li\u003e\n\u003cli\u003eSilver ceramic coating for reduced engine compartment temps and improved corrosion resistance\u003c\/li\u003e\n\u003cli\u003eFree-Flowing For Good Performance\u003c\/li\u003e\n\u003cli\u003eNickel plated steel mating flanges included (mating flange fasteners are not included)\u003c\/li\u003e\n\u003cli\u003eCatalytic Converter Efficiency\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\u003eHi-Silicon-Moly Ductile For Durability\u003c\/li\u003e\n\u003cli\u003e2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment.
