Slo Poke: i lowered it 2 inches....i lowered it because i really didnt like how it sat so high and i felt more comfortable with it lower because i can hold the bike better with my legs when im stopped, and IMO it looks better....as for the exhaust, its super loud, but i havent had any problems with it, i just double wrapped the heat sheilding around it and havent had any problems at all with it

Mturbo2: no, u dont have to take the rim off, but theres some spots around the lip that are a little harder to get to so i just used a tooth brush and some q-tips and dipped them in the thinner and put it on that way for those places
