I have a stage 1 jet and i think you can tell a difference. It sounds deeper, and just feels strong on take off, i can actually pull the fronts wheels without standing on the rack. Its a bid difference. I am thinking about adding a k&n filter to see if can get a little more power. I am in progress of running the vent lines, ill post more pics when completed.
