These headers feature 1-5\/8\" mandrel-bent tuned length primary tubes that will outflow the stock cast manifolds by 46%. These headers are built using 409 stainless steel and feature thick 3\/8\" flanges for a leak-free seal. We designed the headers to incorporate a merge collector (header collector). A merge collector combines high flow and velocity to increase and broaden the engines torque curve, while reducing turbulence that is found in traditional form collectors. When combined with our off-road or catted y-pipes, performance gains increased as much as 10 HP and 20 lbs. x ft of torque over the stock manifolds and factory Y-pipe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFactory Mounting Locations:\u003c\/strong\u003e\u003cbr\u003eThese headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMitered Collectors:\u003c\/strong\u003e\u003cbr\u003eMitered collectors decrease turbulence and increase exhaust velocity.
