Do not use header wraps; they can cause header tube cracking from excessive heat or rust from moisture build-up and void the warranty. Breaking in an engine with ceramic-coated headers can damage the coating and void the warranty. Use cast-iron exhaust manifolds or old headers during engine break-in to prevent coating damage. Ceramic-coated headers require several heat cycles to fully cure before withstanding extreme heat.\nFor additional information about ceramic-coated exhaust products, call Hooker Technical Service at 270-781-9741.","brand":"Hooker","offers":[{"title":"Default Title","offer_id":49715938885870,"sku":"HOK-2840-1HKR","price":1299.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/833e6f1ae660ed77e179ba14a98cd3c34c11d5c0.jpg?v=1791572929","url":"https:\/\/elmosspeedshop.com\/products\/hooker-super-competition-long-tube-headers-ceramic-coated-2840-1hkr","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
