{"product_id":"hooker-super-competition-long-tube-headers-ceramic-coated-29","title":"Hooker 2401-1HKR - Super Competition Long Tube Headers - Ceramic Coated","description":"\u003cp\u003eHooker Adjustable race headers allow you to change your header primary tube lengths, collector lengths and diameters and collector types (Classic 4 into 1, Merged and Split-Flow). By altering the relationship between the primary length and collector diameter and length it is possible to increase or decrease the torque and horsepower output at any specific R.P.M. level. For a slick track the header primaries or collectors can be shortened to decrease the low end torque for better traction. Larger diameter collectors will also reduce low end torque. On a good track with lots of bite, extending the primaries or collectors will pick up bottom end power for a harder launch and awesome e.t.'s. Smaller collector diameters will also increase low end torque. Hooker adjustable headers have taken more Pro Stock drivers to the championship than any other brand.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eLong Transition Collectors\u003c\/li\u003e\n\u003cli\u003eLong Tube Lengths\u003c\/li\u003e\n\u003cli\u003eMonstrous Low-Mid Range Torque\u003c\/li\u003e\n\u003cli\u003eKeep Top End Horsepower\u003c\/li\u003e\n\u003cli\u003eProvides Finest Fit\u003c\/li\u003e\n\u003cli\u003eMost Durable Available\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\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\u003eBrand:\u003c\/strong\u003e Hooker\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\u003eCategory:\u003c\/strong\u003e Exhaust\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Attachment:\u003c\/strong\u003e Slip-Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Diameter:\u003c\/strong\u003e 4.00 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollector Reducer Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Long Tube Adjustable\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\u003eEmission Code:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e GM Big Block\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 Super Competition Adjustable\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\u003ePort Shape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Tubing Diameter:\u003c\/strong\u003e 2.25 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 ga.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWarranty:\u003c\/strong\u003e Manufacturer's Limited 90 Day Warranty\u003c\/p\u003e","brand":"Hooker","offers":[{"title":"Default Title","offer_id":45520677240967,"sku":"HKR2401-1HKR","price":1664.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/89393919f9b49a714d031aecb99433f0.jpg?v=1788268664","url":"https:\/\/checkout.northernperformance.ca\/products\/hooker-super-competition-long-tube-headers-ceramic-coated-29","provider":"Northern Performance","version":"1.0","type":"link"}
