Check with Hardracing.com. They are a forum sponsor. i bought a Yoshimura RS-5 Ti/CF from them and I LOVE it. The system is awesome, Sounds great, and I love it. Only one small problem with the install and thats easily fixable. If you get one I can show you how to do it. The band that goes around the can is so tight its hard to get it around the can and get the bolt through it. What I did was drill a tiny hole and wrap the band around the can and put a tiny bolt and nut to hold everything in line so I could bolt it up to the frame.
Will provide pics and instructions if needed.

Wolfman: Holy shit, it's Viper!
Goose: Viper's up here, great... oh shit...
Maverick: Great, he's probably saying, "Holy shit, it's Maverick and Goose."
Goose: Yeah, I'm sure he's saying that.
