{"product_id":"hooker-competition-long-tube-headers-black-ceramic-coated-5903-3hkr","title":"Hooker Competition Long Tube Headers - Black Ceramic Coated - 5903-3HKR","description":"This exclusive proprietary black ceramic coating offers the nostalgic look of the past as well as the aggressive look of a modern high-tech build.  It also offers a more refined texture and appearance than is possible from painted finishes.  With a satin sheen it has a unique look of its own and in addition to providing a more menacing look it also provides all the corrosion resistance of traditional silver ceramic.\n\nThe Darkside coating also provides improved thermal resistance as compared to traditional silver ceramic (1700° F vs. 1300° F) making it highly recommended for supercharged or nitrous applications as well as for reduced under-hood temperatures.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFormulated to withstand extreme temperatures (stability rating is 1700° F vs 1300º F on silver ceramic) without discoloration  and maintains excellent adhesion even after repeated thermal cycling\u003c\/li\u003e\n\u003cli\u003eProvides a higher heat tolerance threshold than available from silver ceramics (ours or any of our competitor’s) and is therefore recommended for any applications producing elevated exhaust gas temperatures\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency thermal properties limit heat migration through the header assembly, which in turn lowers under-hood temperatures for more performance\u003c\/li\u003e\n\u003cli\u003eIncreased corrosion protection ensures long service life and maintained appearance of investment\u003c\/li\u003e\n\u003cli\u003eProvides unique styling enhancement that is equally pleasing in either a nostalgic retro application or a modern hi-tech build.

Will not fit motors equipped with air injection pump without modification. Hooker Headers for MOPAR 383-440 engines will bolt to the popular B-S heads. However, because the exhaust port centerline on these heads is 5\/8\" higher and 3\/8\" out from the engine centerline compared to stock heads. Some header modifications will be required for installation. Custom header applications will be required for the B-1 heads because of angled spark plug locations. Long-tube headers do not include reducers. 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":49715946193134,"sku":"HOK-5903-3HKR","price":1065.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/f8894fc9524f3c535a7fca9d042b13bcb31134b3.jpg?v=1791572992","url":"https:\/\/elmosspeedshop.com\/products\/hooker-competition-long-tube-headers-black-ceramic-coated-5903-3hkr","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
