The Kooks header and connection kit for 2009–2013 Chevrolet Corvette Base and Grand Sport features 1-7/8" primary long-tube headers mated to a catted X-pipe to smooth exhaust pulses and support stronger midrange torque. Kooks verifies fit and performance through dyno and race testing and produces the kit in the USA to ensure proper installation and consistent results for upgraded exhaust systems.
