There used to be a distributer or service center in Texas years ago for Saito. I had picked up a obselete but new exhaust stack for a Saito .80-90 twin to use on my 100T. I did not like the flex pipes. I had got these back around 1995. I cannot remember the name of the place, but it was an autherized Saito repair place. You could also check ebay, or maybe William in the saito club.
