This is wonderful. I wish they did the same about modifications done to increase the noise. I've got 2 people living nearby that both have straight-piped their car and I literally cover my ears when they pass by. My Watch literally tells me that a noise peak happened when they drive by.
US is all about freedom, and concern for neighbors is a necessary prerequisite to practicing freedom.
PS: I ride a motorcycle as well, there's no problem making it reasonably quiet.
