GT long tubes/mid pipe combo fitment

Most are the same that way. VRS is a company which makes aftermarket mid-pipes for almost all header manufacturers. Bassani is an exception though, because their headers are not a true "longtube" design, they are a "mid length" header in that they don't extent down all the way, the collectors are angled and hookup to the midpipe at an angle (good for ground clearance!).
