Yes, it plugs a hole. Like I said, overall loudness isn't effected much, it just "smooths" out the sound a little, takes the ragged, sharp edges off it. I really think they sound better with the bolt in there. Allen bolt installed .....
I'm happy to see the tapped bars that slide inside the sliding track are included as well. Hanging these off one bolt head doesn't last long on our (vibrating) 650's, lol.
