I have one and it works pretty good! Very quiet at idle, but still fairly loud on the rev. It really cuts down on how far the noise travels though.. you will notice that the sound won't bounce back off tree lines anymore. If you go with the insert you may lose some bottom end power.. the fix is to drop a size or two on your jetting as it runs a little rich with it installed.
