This Kooks kit upgrades its headers and front catalytic connections together, with stepped Tri-Y pipework and heat blankets for the Ultra-GREEN cats. It connects to the factory rear exhaust, giving you a matched front-end upgrade while keeping the rear system you already enjoy.\u003c\/p\u003e\u003cp\u003eSKU: 2181HY30B\u003c\/p\u003e\u003ch2\u003eA matched upgrade for the LT6\u003c\/h2\u003e\u003cp\u003eThe 1-7\/8\" primaries step to 2\" in a Tri-Y layout. Rather than collecting every cylinder into one junction immediately, the pipes merge in stages. That gives this kit a distinct header design, paired with the Ultra-GREEN connections made for the Z06. Oval ports and the stock bolt pattern match the LT6 installation.\u003c\/p\u003e\u003ch2\u003eHeat protection included\u003c\/h2\u003e\u003cp\u003eThe 5\"-bodied Ultra-GREEN catalytic connections and their heat blankets are supplied together. You can plan the front exhaust upgrade with the catalyst heat protection already included. The flanged rear outlets connect directly to the OEM exhaust. Professional fitting is worthwhile on the mid-engine Z06, where access and clearance around the surrounding components matter.\u003c\/p\u003e\u003ch2\u003eTuning for your exhaust upgrade\u003c\/h2\u003e\u003cp\u003eWe recommend tuning with every header installation so the calibration suits your new headers, complete exhaust and fuel. \u003ca href=\"https:\/\/hooniesadrenaline.co.uk\/pages\/contact\"\u003eContact us\u003c\/a\u003e to discuss the right tuning route for your vehicle.\u003c\/p\u003e\u003ch2\u003eVehicle fitment\u003c\/h2\u003e\u003cdiv class=\"table-scroll\"\u003e\u003ctable class=\"vehicle-fitment\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth scope=\"col\"\u003eYears\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eVehicle \/ trim\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eEngine\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eApplicable SKU\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eFitting conditions\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd\u003e2023-2026\u003c\/td\u003e\n\u003ctd\u003eChevrolet Corvette Z06\u003c\/td\u003e\n\u003ctd\u003e5.5L V8\u003c\/td\u003e\n\u003ctd\u003e2181HY30B\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv class=\"table-scroll\"\u003e\u003ctable class=\"technical-specifications\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth scope=\"col\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e2181HY30B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003e2023-2026 Corvette C8 Z06, 5.5L LT6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e304 stainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary tubing\u003c\/td\u003e\n\u003ctd\u003e1-7\/8\" stepping to 2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeader layout\u003c\/td\u003e\n\u003ctd\u003eTri-Y\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCylinder-head interface\u003c\/td\u003e\n\u003ctd\u003eOval ports; stock bolt pattern\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalytic connections\u003c\/td\u003e\n\u003ctd\u003e5\"-bodied Ultra-GREEN; supplied with heat blankets\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear connection\u003c\/td\u003e\n\u003ctd\u003eFlanged outlet to OEM exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhat is included?\u003c\/h3\u003e\u003cp\u003eThe stepped Tri-Y headers, Ultra-GREEN catted connection pipes and the catalyst heat blankets.
