on idle, i can hear a whiny vibration coming from the exhaust area. it comes and goes every 3 - 4 seconds. it's not loud enough to hear it from inside but you can hear it outside of the car.

it could be something like a loose heatshiel or something. that's the kind of sound i'm hearing. has anyone had this kind of problem? i guess i'll have to look under the car sooner or later. but any suggestions would be nice.
