It turned out the baffles in the exhaust separate and vibrate creating a tinny noise. So now my exhaust is being replaced from the catalytic converter back and its all under warranty. Just wanted to post this in case anyone else had the same problem and didn't know what the hell it was.
I knew thats what it is.I took mine in for the same thing and the stupid SERVICE MANAGER tried to tell me it was gear lash sound traveling through the drive train. Uuuh yyeeaa right. I told them it was a harmonic vibration coming from the passeger rear side. I will be taking my car to another dealer on the 17th.
