I was about to order Termis for my XDiavel which i would like to transfer on to a new XDiavel next year. Apparently this is not possible as the exhaust is registered and mapped to the chassis no and cannot be re-mapped to a new bike.They can be fitted but the bike eill run like a bag of spanners. Surely exhausts are not that advanced - but amazed this is what i am being told !!! Can anybody help??
