not sure how it sounds, only seen it on cars at some shows but they look like the kits for 94-98 Stangs. At least this one I saw was a Roush kit and Roush does not make a Fox kit. The guy I talked to said that the wheel base of the SN-95 is close tot he wheel base of a FOX. He did have to do some modification to the muffler mounts but it wokred. I think Spintech makes mufflers for FOX stangs to exit out the side.
