. I've thought of doing it to mine, but also kind of don't care. The bike sounds pretty good when it's in the higher RPMs, and at low RPMs I'm not real interested in being real loud anyway. The valve and wiring are ugly, though - my friend's bike (earlier) doesn't have it and looks much cleaner back there. His Leo Vince pipe sounds a bit better, too.
Yeah, I'm all for being able to keep it quiet at low speeds. No need to piss off the neighbors.
