Have you noticed the number of UK can / exhaust suppliers & manufacturers who have recently started to advertise their "race" cans with BS friendly baffles which can be easily removed & replaced?
 Makes you wonder what they have all got wind of doesn't it?
 As an aside, having just come back from France, I don't think that their clampdown can have had much effect...I can't remember seeing / hearing more than half a dozen bikes with legal cans on!!!
