But then in the city, how do you tell bikes with loud pipes from cars with loud pipes? Several times now I hear this loud rumble, look over and it turns out to be a kid in a civic who replaced his muffler with a noiser.

Of course lets be fair in that the Ninja is far more maneuverable than a big Harley. If somebody changes lanes into them, they just have to sit there and take it, whereas a Ninja could either zip, steer or brake out of danger.
