I can only imagine how loud it must be for someone with a 'paper thin wall' home.

From the posts, I have determined that there is no logical reason for such loud exhaust systems besides it being a way for people to get attention. It also takes a special person, one with a deep sense of apathy and little to no consideration for others, to have such a disruptive 'mod' put onto their vehicle.
