Just put a 9 hawk on my xb12scg shaved 6 lbs and sounds great. sputtered and popped at first on my 08 but after a few miles she got used to it and runs great. not super loud but perfect sound. haven't ridden it hard enough to tell about power yet.
As a side note anyone wondering about the 08 tuning, it seems to have adapted fine to the Hawk.
bump anyone?So what is the difference between the quiet, medium, and loud version in terms of volume and performance?
