i went with a ZG Double-bubble screen...twice! and im about to get a third-dont get the wrong idea, they dont break easily...but when you dump your bike at 50mph, over a curb; or flip it on its head at a stoplight...well, they're sturdy but not THAT sturdy
my fave mod tho-have to be the HMF hi-mounts in CF. Sound is BADA** n just gets better with more revs. Looks awesome too, and gives the back of the bike a "balanced" look with the two pipes. Dont know if i'd ever switch to another exhaust.
