mine are cut but you'll get better performance by just buying some used shorties that came off of someones bike. the flare makes a dif. I just aint bothered with replacing mine yet. Cheap mod.

i changed to short stacks and it seemed to take away some mid range and made the bike feel a little slower so i went back to the orig.
