FYI if you have drone issues with the AA exhaust, I plugged the other 2 exhaust mounts with synthetic wine corks like I did to the other one and wow basically all the drone is gone now. Driving at 2k rpms on the highway is annoying some times but now the 2k rpm range is smooooooth and drone free. (maybe 10% of quiet drone left)
