{"product_id":"hooker-competition-long-tube-headers-ceramic-coated-2456-1hkr","title":"Hooker Competition Long Tube Headers - Ceramic Coated - 2456-1HKR","description":"Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5\/16\" machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance. Hooker Competition headers have a standard finish that features a heat-cured, high-heat-resistant paint. Optionally, the famous Hooker Ceramic Thermal Barrier Coating is available.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAll necessary hardware included for a complete installation\u003c\/li\u003e\n\u003cli\u003edesigned for easy, trouble-free fit\u003c\/li\u003e\n\u003cli\u003eIndustry’s best welds for durability\u003c\/li\u003e\n\u003cli\u003e5\/16” machined flanges for a perfect seal\u003c\/li\u003e\n\u003cli\u003eLong transition collector for decreased back pressure\u003c\/li\u003e\n\u003cli\u003eLight weight \u0026amp; sturdy 16 gauge tubing\u003c\/li\u003e\n\u003cli\u003eMandrel-bent tubing for smooth exhaust flow\u003c\/li\u003e\n\u003cli\u003eTuned-length primary tubes for better performance\u003c\/li\u003e\n\u003cli\u003eWorks with power steering, power brakes and air conditioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Long Tube Headers for 1955-1974 Corvette with 265-400ci V8 engines, Primary Tube Size 1.625\" x 24\" O.D., Collector Size 3\" O.D., Collector Length 8\", Header Port Shape: Same As Engine Port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Injection Tubes:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Size:\u003c\/strong\u003e 3\/8-16 x 3\/4 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolts Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalifornia Proposition 65:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalifornia Proposition 65 Chemical List:\u003c\/strong\u003e Chromium, Nickel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCARB (California) Compliant:\u003c\/strong\u003e For Pre-1975 Vehicles only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Attachment:\u003c\/strong\u003e 3-Bolt Flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Diameter:\u003c\/strong\u003e 3.00 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Outlet Diameter:\u003c\/strong\u003e N\/A IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Long Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive:\u003c\/strong\u003e 2WD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGT Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e Chevrolet Small Block Gen I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Ceramic Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Thickness:\u003c\/strong\u003e 5\/16 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Or Seal Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Series:\u003c\/strong\u003e Competition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeader Style:\u003c\/strong\u003e Long Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Mild Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOxygen Sensor Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Exhaust Header\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Shape:\u003c\/strong\u003e Oval\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Tubing Diameter:\u003c\/strong\u003e 1 5\/8 IN, 1.625 IN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Headers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e Sold as a Pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Wall Thickness:\u003c\/strong\u003e 16 GU\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\nWill not fit with angle plug heads or raised port heads. Installation requires air conditioning bracket 10925HKR left side or 10926HKR right side. On 1979 and later vehicles with short compressors, use stock bracket. 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":49715936362734,"sku":"HOK-2456-1HKR","price":727.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/9110\/6798\/files\/0713cbb6a3f35b23b2e86acc3eea316e03312826.jpg?v=1791572890","url":"https:\/\/elmosspeedshop.com\/products\/hooker-competition-long-tube-headers-ceramic-coated-2456-1hkr","provider":"Elmo's Speed Shop","version":"1.0","type":"link"}
