I got mine from Eisenhaus (
www.eisenhaus.com) out of Chicago...they got a great web site...Ipreferred ordering directly so I called and worked on the phone. Also they do have the loud and quiet option available. The one that I got is the Race exhaust (loud) but they also offer a Sport version which is much quieter. On their website click on the Exhausts links and go from there....Need more info PM me and I will fill you in with more info. The price has changed now but when I bought mine (6mths ago) I paid $1680.00.
