Been looking at my nice new 1100GS exhaust which I collected at Verns today from Big Den and see its got an E marking on it. Had a look at the titanium one that's been on since I got the bike and it has no markings on it, not even a "Not for Road use" etc etc 
The titanium can is a straight through one, but the bike has recently passed its MOT and isn't very loud, IMO. The bike does have the Remus alternative mid can, ie not the single pipe that is thought to be fairly loud.
With no markings at all, where is the bike in the legal quagmire of "E" markings / MOTs / etc etc?
