Europe has fairly strict sound limits on motorcycles (and they are getting stricter) in euro4/euro5. This constrains the manufacturers, but aftermarket enforcement really varies by location.

These days a lot of manufacturers homologate to meet multiple standards, so we get euro4ish stuff in north america too, stock at least.

Yep, it's not so much the production limits (still, they could be pushed gradually lower and I'm sure the manufacturers would manage), but it's the often grey-are of aftermarket modifications.

Also, I think European houses and apartment buildings are built from brick, stone and concrete, while in US most of "homes" are wood and drywall, which doesn't isolate as well.

All I can say as a motorcyclist myself is good.

After market exhausts that aren’t engineered to be deliberately louder are stupid and annoying to other people.

I suspect you meant engineered to be quieter?

Excluding intentionally loud exhausts, the intake on a lot of bikes generates more sound than the pipes, at least at speed.
