I had the Leo on my bike when I first got it. It sounded nice but it didn't follow the lines of the bike that well. It also stuck out pretty far and the midpipe was in the way of your right ankle.
Yeah, the Leo looks like a fine piece to add to a bike, but I always thought it was a bit on the long side and I would like a mid that makes the right foot position better, not worse. Thanks for the info on it though!
