Sounds good to me gents, just need to get rid of the plug ugly standard cans! My vote would be for the twin pipes every time even though they will undoubtedly weigh more than a single system.
Just goes to prove how shallow I am........more interested in it looking right than being light coz if I was that bothered about weight I'd have bought a KTM690 Enduro.
....mind you, then again I'd have had to be colour blind like all my mates who can only see in orange
