Solution: I'm looking for one!

 

Sounds more like a rattling heat shield to me. I'd get up under your car and just poke around looking for something loose.

 

I'll take a look, but it sounds like more air is trying to escape through a small hole more than metal rattling, ringing or pinging.
I drove it all around yesterday and the problem doesn't seem to be getting worse.

 

get a nice clean ball cap, lean it to one side of your head, don't fold the bill. lean over your steering wheel and with one arm do a "bouncing" jesture while saying "yo!! wut up G!!"

noone will thing anything of your car but you having an after market exhaust.
