The product installs quickly and easily, however, it doesn't allow an aftermarket spark arrestor and end cap to fit flush. (Big Gun Spark Screen). I managed to make both fit, but the end cap sticks out a little.
It will only fit if you have a Big Gun exhaust. It will not fit the stock exhaust or exhausts from other manufacturers. If you can give us a call we can help get you the correct quiet core for your bike depending what exhaust you have.
