Built from mandrel-bent 304 stainless steel, these headers replace restrictive factory manifolds with a design that improves exhaust gas flow, enhances throttle response, and increases horsepower and torque - with gains up to approximately +11 hp and +13 lb-ft torque.\u003c\/p\u003e\u003cp\u003eFeaturing heavy-duty laser-cut flanges and mitered merge collectors, the 48-38031 headers reduce exhaust turbulence while maintaining a direct bolt-on installation that retains factory oxygen sensor locations and does not require cutting or modification of the stock exhaust system. Precision engineering and 100% MIG-welded construction ensure long-lasting durability and a secure, leak-free fit. Note that while this part meets Federal emissions standards, it is not CARB exempt and may not be legal for sale or use in certain states that require California emissions compliance.\u003c\/p\u003e","brand":"aFe","offers":[{"title":"Default Title","offer_id":55141337104703,"sku":"AFE48-38031","price":1223.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/92eaa84d20b6784bed6c64408e46aa01.jpg?v=1787149341","url":"https:\/\/wcaperformance.com\/products\/afe-21-22-jeep-wrangler-392-twisted-steel-header-1-7-8-in-to-2-3-4-in-304-w-raw-finish","provider":"WCA Performance","version":"1.0","type":"link"}
