To eliminate the RPM swings in A4 mode, I have been going into manual mode on the highway. Now I really notice an exhaust drone at 70+ MPH in 8M.

Anyone else notice this? Would changing the exhaust mode alter the drone?

Do you have your NPP fuse pulled? If not, putting NPP in Tour mode should take care of it.

My Z06 will drone with engine sound management set to track at interstate cruising speed, I switch the sound management setting to sport and that takes care of the drone. I found that the Blockit mat I added also somewhat reduced the drone but sport is still noticeably quieter at cruising speed. Mine is a 2016 and as I recall some earlier model years only had an auto or off setting for engine sound management but if yours is a 2016 or later you can go into vehicle personalization and switch sound management to sport and that will probably take care of the drone, otherwise try setting to tour.
