It was a almost a straight pipe, fitted with no problems on the Trial Blazer 250, what I did'nt know was that you had to use the OEM header and exhaust flange #9 and #10, you would have thought they would have made those items as part of the pipe.
Plus I had to send them out to be ceramic coated to match the rest of the pipe. From now on, I will just go and have my pipe/silencers custom made from now on.
