Yep. Bluetooth speaker plugs into the right side and is tubed thru to the exhaust. Actually sounds pretty decent, and happy accident, the whole base of the unit turns to control the volume. So I can reach down and turn it up or down while riding. Kinda neat. I'm going to mask off and paint the inside of the tube paprika to match everything else.Amazing piece you've come up with here Carl. Love it. So the exhaust pipe is like a speaker deal?
