It takes a lot of time and money to do the job right. We will sometimes spend up to 2 to 3 times more just to make the Super Competition header work only 5 to 10% better. That commitment to excellence has made Hooker Headers the winningest header manufacturer in automotive drag racing history. Hooker has a complete line of engine swap headers, front frame mounts and transmission mounts for popular engine swaps. Available for Chevy, Chrysler \u0026amp; Ford small block and big block engines. Hooker swap headers and mounts are designed to provide an exact fit when used together.

Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. Please call Hooker tech service at 270-781-9741 for additional information regarding ceramic coated exhaust products. The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty. Hooker long tube headers do not come with header reducers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHooker\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCollector Diameter\u003c\/td\u003e\n\u003ctd\u003e3.50 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEmission Code\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeader Finish\u003c\/td\u003e\n\u003ctd\u003eBlack Paint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeader Style\u003c\/td\u003e\n\u003ctd\u003eLong Tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Tube Dia.\u003c\/td\u003e\n\u003ctd\u003e2 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eHeaders\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTube Material\u003c\/td\u003e\n\u003ctd\u003eMild Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarning\u003c\/td\u003e\n\u003ctd\u003eCalifornia Proposition 65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Hooker","offers":[{"title":"Default Title","offer_id":31704744886321,"sku":"2217HKR","price":666.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2493\/0960\/files\/2217hkr-564bca53a7e8ac1c69c629a1aab282d2648d7301.jpg?v=1759634218","url":"https:\/\/moderndaymuffler.com\/products\/2217hkr-hooker-super-competition-long-tube-headers-painted","provider":"Modern Day Muffler","version":"1.0","type":"link"}
