sure nice sound is in the 'ear' of the beholder, but i'd say 9/10 times it's the driver and how they are behind the wheel who attracts unwanted attn to his/her ride. I can truly appreciate the sound of a nicely cammed old school v8 rumbling the pavement, actually enjoy the sound of "good" exhaust on a boosted 4, and dont mind a nice bike either. I've had 2 of the 3 listed, but was always smart enough to play where it wouldnt affect others.
Now if you have uncorked the headers and it sounds like race day in your drive.... well that may very well get you a call from your HOA.
