Probably difference between USA and Europe. In Europe beat up cars will not pass technical checks. To have a really loud car you have to replace the exhaust for the check and then install the custom one again. Only special kind of drivers have the time and will to do it. Mostly bikers.
That actually probably explains why bikers do it the most since there it seems like on most bikes the swap can be done in less than 30 minutes as the exhaust system is small and self-contained and easily accessible
Motorcyclists also believe a loud exhaust makes them more visible to drivers - to what degree this is true is debatable but sometimes the motivation is not pure malice like with cars.
