Product Description

The Kooks 2160H421 long-tube header and catted X-pipe kit is engineered for the 2005-2008 Chevrolet Corvette Base models equipped with LS-series V8 engines. This high-performance upgrade replaces restrictive factory manifolds with free-flowing 1-7/8" tubing and a high-flow catted X-pipe, resulting in enhanced exhaust scavenging, reduced back-pressure and a richer exhaust note. Whether you're on the street or prepping for track performance, this kit offers substantial upgrade potential.

Installation is designed to maintain direct-fit compatibility for the specified Corvette models, using factory mounting points and position. The polished stainless finish adds a performance-orientated appearance beneath the vehicle and the included catted X-pipe supports a more aggressive sound while retaining emissions cat function where required. Before purchasing, verify your exact vehicle's year, engine size, trim, drivetrain, and existing exhaust layout to ensure full compatibility and correct installation.
