Quiter/sexier exhaust?

[dogwhistle]

So I figured out my plan of attack. I will be in search of (and happily taking any donations of) stock mufflers as well as a twin loop muffler. Once I attain one or both I will post some sound clips of my friend's (Bad Omen Racing on here) straight pipe 2.5" setup as well as my 3" with a straight through 3-4" muffler, and the above mufflers in an effort to figure out sound quality or tone vs decibel levels.
