go to renegade's website... apparently its not too hard to install, you just put on their special undertail and hacksaw off the bungee hook rails. The systems ranges from $1000 to $1400 i think, depending upon the type of cannisters.
Bekieve it or not that system will probably dyno higher than anything you could out on it. I rode that bike in the picture. Second gear wheelies with ease in front of Brands Hatch. It broke 80 horses on the dyno.
