Very easy install. Took my tech about 20 min from start to finish. Seat of the pants says there is hella power to be had. More power on initial throttle onset and feels more powerful up top. I need a tune so bad now. I've done so many more modifications and feel I'm in desprate need of one. I have to hold off till the longtubes go on as well as the gears. The long tubes came in but you won't believe what happened when I opened the box.
