Not as far as I'm aware. From what I've seen so far, the Danmoto Jisu with baffle installed seems to be the quietest, but it's not stamped as legal in the UK as far as I'm aware. It may get through the MOT, but that would be entirely up to the tester at the time, and not guaranteed. That's three years off a new bike though, so no big worry immediately. Could be a problem insurance wise though. Welcome aboard Lady Vampire21.
