I love the sound of a turbo with only a dump pipe. My FZR sounds awesome
with no muffler. I'm using a relatively small turbo (t25) and it's not too
awful loud. It's certainly not near as loud as a stroker with a megaphone.

 And the way people look at you at stoplights when you rev the bike and it
makes that zimmm, zimmm, zimmm sound...........
