Manny, the existence of a removable baffle does not make the can lroad legal. Just to avoid any confusion, as I said in my post, I have just replaced my first Akro can with the BWM Akro, the first was definately stamped 'not for road use' and had a removable baffle. The BWM one has the 'E' stamp showing it is road legal and as mentioned previously has the BMW stamp on the back.
Performance wise, who knows, haven't ridden the bike with the new can on, but it sounds great with the baffle out, and looks superb, really enhances the look of the bike. Without putting it on the dyno, difficult to tell anyway.
