I just called both local yamaha dealers up here in alaska to see if they had the pro circuit pipe the only one they have is the white brothers and they said that is the only one they can get, except for one called the pro tech buti have never heard of it and he said he had been dealing with them for years, has any one else heard of it and if so is it a good pipe. and does anyone have any numbers I can call for the pro circuit. It would be much appreciated thanks
oh yeah check the site out

 

go with the big gun, pick up any dirt wheels and order from there. I have one with the dynojet jet kit and love it
