Also - are your valves open in comfort too? Maybe its just the mic, but I can hardly tell a difference in volume between sport and comfort outside of the burbles.
Yes. Comfort quiets it down and takes away burbles during cruise and idle. Mic was on license plate so not a good idea of what it does I guess. There’s only 1 valve on these so it doesn’t quiet it as much as my g80 with 2 it seems.
