I think the level of irritation that occurs with the sound of a loud muffler comes with age. When one is young it signifies toughness, or being cool. Then, you start to outgrow it and soon you're thinking "wow, that guy needs a new muffler"! Doesn't matter what age you are or why your muffler is loud. If it's too loud, the Duluth Police Department is going to do something about it if you don't get it fixed.
