I see a racer in training ;D
Any name-brand exhaust is going to be good...they all sound and look just a little different.
If you don't want to spend $300+, look at the Delkevic on eBay. I just installed one on my SV and couldn't be happier! It sounds good (better than a friend's M4, in my opinion), looks good, fits well, and, best of all, it's a great price.
