Twisted Steel? headers. These headers feature a 1-5\/8? mandrel-bent tuned length primary tubes that will out-flow the stock cast manifolds by 46%. These headers are built using 409 stainless and 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 turbulences that are found in traditional form collectors. When combined with our off-road or catted y-pipes performance gains are increased as much as 10HP and 20 lbs. x ft of torque over the stock manifolds and factory y-pipe.\u003c\/p\u003e\n\u003cp\u003e3\"-3 1\/2\" Mandrel Bent Tubing; 409 Stainless Steel; No Modification Necessary; Factory Mounting Locations; Direct Bolt-On; Increases Flow and Performance; (14 gauge) Thick Stainless Steel Tubing; Mitered Collectors\u003c\/p\u003e\n\u003ch4\u003eFeatures \u0026amp; Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14 Gauge Thick Stainless Steel Tubing\u003c\/li\u003e\n\u003cli\u003eIncreases Flow And Performance\u003c\/li\u003e\n\u003cli\u003e3-3.5 in.
