As far as I can tell, you have four basic options:

Pacesetter, Borla, SLP, or Custom... read enough using the search feature with those names and "exhaust" and you can find SO many posts about it.. each has a unique sound and each offers pretty much the same performance imo.

I have the pacesetter, its going on tomorrow, and so far, for 250 bucks i cant complain. The tips arent awesome, but they look better than the ones u had posted up... quads are great too... like dual, with dual tips on each one... lol
