Just installed a Leo Vince slip on I bought from a forum member and LOVE it! I was worried because of experience on 2 other bikes that it wouldn't run as well. It runs great and sounds awesome. I left the silencer in so not too loud just a much better sound. Very slight popping on hard deceleration. I was planning to plug the pair valve hose but no need. And this is the first time I had the potato launcher/bazooka off the bike. What a beast! The Leo Vince has got to be 20lbs lighter.
