it is a misconception that the raptor exhaust wont work on the warrior. As Dave said the only differance is the mounting tab location on the silencer. All you need is a small piece of flat iron, a drill and 5 minutes, and then your golden. Hell some aftermarket exhausts use a band clamp that allows you to move the mounting location. Hell with a welder you can make almost any silencer work. On my old 87 warrior i put a raptor 660 silencer on.
