Anyone go with this exhaust. I was gonna buy a used w/b system but it was sold. I have heard some good things about these guys but it was always on old bikes like the 400's and 426's. I wanna hear about the 450 gains. I think mostly what bothers me is that they are a small company. If I shouldnt get these guys what is the best brand of slip on exhaust for the best price. (Nowhere above 330) Doesnt fmf sell theirs for 299? It says in dirt rider.
