i put a custom duel exhaust on my svt and it looks pretty cool. if i knew someone made a kit i would have gotten it. saleen also makes a duel kit. it exits out the middle though but, it looks good. i plan on puttin a 21/2in. custom exhaust from the cat back and running a flowmaster 0 in and 00 out and tieing back into the 2 pipes i have on there now. ive already gotten a few comps on it from some gt mustang guys on looks and deeper sound.
