I haven't' heard any of these...yet...
I know there are local noise level ordinances, and I thought there was a generic ordinance on CA that prohibited any exhaust modifications whatsoever on emissions-controlled vehicles, but I'm not certain.

The DOT has received a number of calls from city police and state highway patrol offices regarding a exhaust fad that's been starting in the north western united states. Attached is a link to a news report on the subject.

I only have four words for this... "I don't get it". From what I heard in the video clip, I just didn't see what the attraction was. And it was installed on that station wagon?
Exhaust modifications on a an emission controlled vehicle is up for interpretation and since this "whistle" is installed at/in the exhaust tip, they are within the Law. If anything, they might be on the border of excessive noise (db levels) but even that is a grey area.
Pam got me a new exhaust tip for Christmas which is a bit wider than my old one. It's a Ractive Round/Angle tip (http://www.toucanindustries.com/index.php?src="">) and it changed the exhaust tone. It's still mellow sounding (no raspiness even when I get on the throttle hard) but it is a tad bit louder than before but not a lot. I still maintain my nice somewhat low mellow exhaust tone.
FWIW, my CRX whistles too but it's from inside the intake. It's always done it ever since I got the car and it's become a signature sound for me. :^) It only does it under load. I suspect that it's something inside the throttle body when air is rushing pass. I should get one of those whistlers for the exhaust to help round out the sound! ;^P
