dont know how much the mods will like what i have to say but i asked the same question a while back and just got the answer "search"... well if you wanna check out themustangsource.com forums they have a good compliation of exhaust clips as a sticky under the performance section. it helped me alot to choose bassani.. now all i gotta do is order and install.
P.S. im loyal to stangnet, infact im not even a member at the other site! dont take it the wrong way mods! but a good exhast sticky couldnt hurt...
