Anyon had any problems with these ? I bought one a while back from Dirtoverstaock and tried to fit it but theres no way.The pipe will have to be cut and extended after it turns from the exhaust port so that the mid section clears the downtube .At the moment the pipe miss's the exhaust port by about half an inch with the mid section hard on the frame.Another guy who race's VMX in Victoria told me the exact same story. >:(Anybody else?
