Notes: 1. Systems are designed to connect to full length aftermarket headers, please specify collector size when ordering. Downpipes are available for many Buick applications, in order to connect to exhaust manifolds or our Shorty headers. 2. Systems are not compatible with F-body convertibles that have a reinforcing under body pan. 3. F & X Body systems require short case mufflers.
