I saw a guy on a Gixxer 1K, at a gas station with one of those, he said he had to order it from Japan ??
Are you sure that wasn't just cut down ? They do look good. GPW (Greg, from Hyperbike Performance Center) cut a Ti Force down to about 8 inches for somebody, and I saw it when I was there. One of the nicest exhausts that I've seen !!
