For anyone searching...
Just did the Flap Delete on my 2011 R1200GS, and there were no fault codes.
Little bit more aggressive "bark' to the exhaust note, but the biggest difference I've noticed (and didn't expect) was a more immediate throttle response, not sure why???
So this completes my exhaust upgrade:
Akrapovic Headers (cat-less)
Black ceramic coat on headers
Remus Hexicone silencer
Wunderlich Flap Delete kit
