I have never had any issue on the road with any exhaust, i am more concerned about track days as it so hard to get through the noise limits.
I have had full systems on both my 2010 & 2012 and the dealer has never said a word with warranty claims i have made, in fact they normally think it's great and love the sound......If (very unlikely) you have a major engine problem then they have to prove it was the exhausts fault. I have had PVC's on both bikes and never took off when having service or work done and never a word has been made to me....BMW have always been great to me with cars and bikes and i have had lots of bits done free of charge when car or bike is out of warranty as a good will gesture, In fact i had a new clutch put in my old M5 which was 8 years old free of charge which normally costs ?4000!!!!I would stay with the Akro system from the dealer. I'm getting mine installed next week.
If you want the AR, it really depends what your relationship is like with your dealer. In theory, if BMW ever felt that the AR system contributed to a fault in the bike, they could certainly try and reject a warranty claim on that basis. Another thing I have heard repeatedly from various dealers - even though it sounds like an urban myth - is that because of the nature of the RR, the minute BMW know you've installed an actual full 'race' system, they will automatically deep it to be a 'race' machine and void the ENTIRE warranty altogether. This wouldn't happen if you installed a de-cat system on a GS, but I suspect because of the nature of the RR as super-sports bike, there would be more reason for the company to believe that the bike being used in racing.
