The Kooks header and connection kit for 2009–2013 Chevrolet Corvette Base and Grand Sport includes 1-3/4" primary long-tube headers paired with a catted X-pipe to improve flow and responsiveness across the rev band. Kooks produces these systems in the USA, tests them on the dyno and in racing environments, and designs them to provide reliable fitment and enhanced exhaust performance over stock components.
