Do you contact whoever is responsible for enforcing noise stuff?

It's useful to keep a diary for a month. Include photos and videos. If you can dedicate a camera for a month and keep that in a fixed place it helps.

You then make notes of all the details in the photos - licence plates, desceiptions, times, dates, etc.

Dump all of that neatly collated information in the hands of whoever does the enforcement and see what happens. Do it for a few months if nothing changes, and escalate after a few months.

noise ordinances are often about sustained noise for longer than a few seconds, constantly above a certain decibel limit. you're likely to find that construction, large vehicles, and other things nearby are as much of a nuisance from a measured standpoint.

If that were true, towns would not have "No compression brakes" signs at the town limits. No one wants a loud ass Harley ridden by wannabe outlaw bikers waking their baby up at 2:00 a. m. That's one reason noise tickets are written (though not nearly often enough) for those with open pipes.
