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\u003cp\u003eTwisted Steel 409 Stainless Steel Short Tube Header Ford F-150 11-14 V8-5.0L\u003c\/p\u003e","brand":"aFe","offers":[{"title":"Default Title","offer_id":51367663960376,"sku":"A007 48-43001","price":1236.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-16034-4611541-square.webp?v=1779206762","url":"https:\/\/store.motormia.co\/products\/afe-twisted-steel-headers-ss-409-11-14-ford-f-150-v8-5-0l-race-only","provider":"MOTORMIA","version":"1.0","type":"link"}
