As a motorcyclist, I'm firmly in the camp about quiet, stock pipes.
If I was dictator, I would impound and destroy any vehicle that was too loud.
I've been told the number of people driving with loud exhaust is a function of how close you are to the nearest meth house. This is after adjusting the data for level of travel a given road or nearby road
I live near a school (equivalent to middle as well as high school). The rest is a purely residential area.
I feel that living near a school in the morning with mommy driving little Kevin to school in big SUV and little Kevin's older brother revving his engine as much as he can with his car comes probably somewhat close.
