sweet good to know. i orig wanted one for my race bike but that bumper idea is cool too bc i have the Dinan midpipe and muffler and would like to hear it from the back like you did instead of the normal ones you hear. i am def getting one so i can hook to my helmet or race bike and now the car.
good stuff look forward to more vids thanks
