Upgrade the exhaust side of your 2027+ Chevrolet Corvette C8 Grand Sport 6.7L with the Kooks 2-Inch x 3-Inch Stainless Steel Long Tube Headers. Designed for performance-focused applications, these headers feature large 2-inch primary tubes feeding into 3-inch flanged collector outlets to support increased exhaust flow and a more aggressive long tube header configuration.
Kooks engineered these headers with oval ports, the factory bolt pattern, and 3-inch flanged collector outlets designed specifically to connect with Kooks OEM Connection Pipes. An installation bolt kit is included, but header gaskets are not supplied. Installation requires reusing the factory header gaskets or sourcing a new replacement set from Chevrolet. These headers are not intended for use with the OEM catalytic converters and require the appropriate Kooks OEM Connection Pipes.

The larger tube sizing and long tube configuration make them a strong choice for performance-oriented builds where exhaust flow and supporting modifications are a priority.
