I saw an advertisement for FTZ racing in the back of a dirt wheels magazine so I deceided to go check it out. They offer this really fat pipe that is the biggest I've ever seen. I've heard about these pipes before but I have no idea what they perform like. I did see one at the danville TT national in VA. Some guy on a black 250r had one and won the 250A class. Does any one have one, used one or know any one who has one? They look pretty cool and I am considering getting one.
