To hear a very big motorcycle go quietly by in the dark!
Quiet stock exhausts just make me think of well built machinery....and riders with nothing to prove.
To each his on.....as long as. Naw, won't go there.
I remember a buddie's BMW .....almost had to touch it to see if it was running.
Poor guy had to put up with a bunch of two strokers when we were in Medic training in the 60's.....sounded like a flock of over-reving weed eaters ringing bells. (I think a few were Bridgestones ??)
