Asking people to rate the volume of their exhaust on a scale of 1-10 is about as scientific as measuring with a micrometer, marking with chalk, and cutting with an axe. It's so subjective that you're not going to come up with any conclusive data.
What's loud to one person will certainly not be considered loud by another, and vice versa. Some people think that these cars are too loud inside
stock.
I say 7.
