The purpose of an exhaust is not to disturb.

I think you’re straw manning my argument, where I conceded that absolutely some people go too far and are obnoxious. The civic at 2am example is a great one, street racing late at night is another, and I agree with you that’s unnecessary.

My argument was simply that I have yet to see an implementation in proposal that stops the above, without also making the factory exhaust that’s barely above road noise level on your average sports car illegal. Where do you draw the line? How do you get people to agree on where the line is? Do you make exceptions for things like performance vehicles/supercars? You’re not going to find consensus among the population besides for most of us it’s a non-issue that nobody even thinks about.

I'm not sure what's so hard about the line. Most municipalities already have the line well defined. They have noise limits that are different in residential and industrial areas, and are lower during normal sleep hours.

If it means that you can't stomp on the accelerator in a residential area in your stock performance vehicle at night, so be it. Yes, some legally stock vehicles are loud when driven hard. So don't drive them hard when that's inappropriate.

Yes - I agree with you. Some of the commenters above have conflated “an annoying person drives a straight piped mustang through my neighborhood” into “every car is bad”.
