I bought my pipes from ftgracing4 on ebay ,good guy to deal with .He said the pipes were used for a photo shoot and other than that they were never used.the PIPES LOOK SWEEET!!! the silencers look a little cloudy ,no big deal.i got a chance to hook up one sideand everything fit perfect except were the pipe mounts on the jug, it leaked a little.the oring groove is to deep.So what idid was put another oring,one size smaller,were the jug stops against the inside of the pipe.the springs had to stretch a little further but it stopped the leak!!!!
