I was surprised at the size of the Leo. It is about half the thickness of stock and about 1/2 the weight. I forgot to weigh it, but it sure feels that way.
Might as well give my feelings on the spacer setup that is supplied with the Leo. When installed according to the directions, the tail end of the can hits the exhaust shield. This in my opinion really looks crappy, but if you don't use the turn down silencer it has to be done this way.
I used the above silencer and eliminated the spacer. Kinda modified the mounting a little. Now it is much tighter to the bike and no problems with heat.
With the can tucked away, the tip really does not look bad.
