Yeah, I'm not quite sure what to do about the traffic. The other forum won't let me post links on it to this one. The forum software and usability is certainly better here.

The Borla/Corsa/et all exhausts should all be direct bolt on but I don't know if I could say with any confidence that you would gain any hp with a cat back system. If, however, you went with a long tube header setup you would get some added hp. I havn't seen any headers yet for the V though.

If you're in Dallas, swing by LG Motorsports and see if they have any cat back experience with the V. LG makes an excellent long tube header setup for the C5/C6 Corvette.
