I have a custom 900, $1,400 in savings. I want to upgrade the exhaust, I already know I want the vance & hines dual slash staggereds, but I have no idea on the airkit and power commander. Any advice would be great. I can't find the info on previous threads. Do I have enough money to get these three items? The pipes are around 400 but from there I don't really know. What I need to know is what brand airkit and power commander would go best with the pipes, and size bike I have. Thanks to all for looking at my thread! Love this forum.
