I got 12lbs for my stock exhaust, on my crude scale. I used a DG slip on, which is no where near as nice as the Leo. It is a little loud, but only 6 lbs. With the JD jet kit, air box mod, and slip on, it really woke up the bike. After removing the license plate holder, and hardwar, foot pegs, and lighter handle bars, I lost about 14 lbs total including the slip on. I heard you can save up to 7 lbs using a lighter battery. That would be around 21 lbs total. I noticed the difference with just the 14 lbs.
