I still think a single or twin with tuned length open pipes sounds beautiful...although any Japanese bike with open pipes sounds horrible. My R65 runs a Supertrapp and is hard to keep under 100db....I hate it with stock mufflers, and mine aren't stock anyway. The Boi Racers ruined it for all of us, but there seems to be less of the car on bump stops and huge can around these days, so maybe it did work after all.
