It just adds up, you know? I own a Porsche and I purposely left the sports exhaust option out (even though you can turn it off, I wasn’t sure if it wasn’t still louder then). Because if using my fun car means annoying everyone else in a radius like they are annoying me when they pass my house, it wouldn’t be that much fun. Can’t imagine what it must be for parents of young children, when some exhausts are loud enough to wake me up in the middle of the night (and the surrounding car alarms).
