Very popular line of thinking with people who own (e.g.) Harley-Davidsons… which are loud out of the box.
No they are not, at least not in the U. S. Thé EPA dictates a max dB sound output, and HDs must meet it, like everyone else. Stock HDs sound quite nice.
Of course, you might not know this because no real American leaves a HD dealer with the stock exhaust installed.
The aftermarket for noise scofflaws should not exist. I lived near some kind of chopper club years ago and every Sunday around 10am you'd have these clowns revving loud enough to nearly make eardrums bleed. I theorize the reason they feel comfortable inflicting this on others is because they have the admiration and encouragement of the individuals on the police force who would do the same with their cruisers if the city would buy the parts. Pox on all of them in this narrow regard.
