Just got back from talking with the reps from Kuryakin @ Street Vibrations, I am looking at changing the stock exhaust on my 03 RK. They were talking about their Crusher True Dual, a Hypercharger and the V&H fuel pack. I was led to believe I would gain approx. 15 hp and 40lbs torque. Are these #'s in line or are they just shooting me a line? Has anybody done these mods to an 03 RK and if so how does it perform? Any and all help is appreciated.
