I agree with 95 warrior. I have the stage two dynojet kit with stock pipe and a huge airbox lid modification. I guarantee I picked up four horsepower in the meat of the powerband. No doubt about it my raptor wheelies in fifth gear with a little yank now. I have no Idea how much it would help an aftermarket pipe.

I am going to try to take it out tomorrow and see what it does. So far it seams really responsive, with explosive power [img]i/expressions/face-icon-small-happy.gif[/img]
