1-3/4" Primary Long Tube Headers

The Kooks Headers 21502200 are long tube, stainless steel headers engineered to enhance performance for 1997-2004 Chevrolet Corvette C5 models equipped with the LS1/LS6 5.7L engine. Featuring a 1-3/4" primary tube diameter and a 3" collector, these headers are designed to optimize exhaust flow. They are constructed with a round cylinder head port shape and employ a ball and socket flange for secure collector attachment. This race version includes O2 fittings but omits emissions fittings. Installation of these headers requires the use of a Kooks X-Pipe, as they do not connect directly to the OEM exhaust system. The headers are built to order in North Carolina, with an estimated shipping window of 4-6 weeks. Customers seeking faster delivery are advised to contact Kooks Headers or locate an authorized dealer with available inventory.
