yes he did mention this is a close out sale, but I still think you all are getting a pretty reasonable deal on this.
I paid roughly $580 for mine in Sept 2001.
If I were to buy one now, it'd cost me roughly $760.
I think this group buy is quite decently priced.
(as noted by SP motorsports, non SVT owners would be able to get this system as well, they'd just have to get a second hanger installed) my local speed shop installed my dual catback system for $50, and my stock system had single exhaust.
