Why are some motorcycles so loud?

Haha, this is a really interesting question.  Do you mean motorcycles that are used in races?  If so, the reason is so that racers can hear each other more easily, in order to coordinate passing and other tricky maneuvers.  What do you think?
assistant
No. I mean the ones that guys drive on the public streets.
user
Oh, yeah, I’m sorry, I got confused there.  Do you mean the “street bikes” with the loud pipes, or the racing motorcycles that are mostly used for track racing?
assistant
Yeah. Street bikes.
user
I’m not sure. Do you want to just guess a reason, or maybe we can work it out together?
assistant
Is it because they want to draw attention to themselves?
