The 92-95 ex/si and the 99-00 si are not speed goverened. U.S. Hondas that are goverened usually top out at about 120mph, I live in Germany where the speed limit is your gut, go as fast as you want but if your scared the your going to fast. The 99-00 si tops out at 148-154mph and that's bouncing off of the rev limiter.
