Kooks 3" x 3" catted stainless X-pipe — true 3" all the way through with standard race cats inline. For C5 builds running a full 3" race exhaust where the catted version keeps them street-legal in most jurisdictions.
Fits 1997-2004 Chevrolet Corvette C5 LS1 / LS6 5.7L. Requires Kooks long tube headers. Does not connect to OEM-style cat-back — pair with a 3" race tail section. Standard race cats are NOT for use on forced-induction applications.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every mid-section is welded by experienced fabricators in the same shop where the company's racing roots were established. 3-piece design for improved fitment.
Includes 3" x 3" mid-pipes. Pair with Kooks C5 long tubes upstream and a 3" downstream system.
