sound from right rear wheel area

[ron]

I have recently noticed a sound coming from the rear of Vette when it is started and when it moves at a slow pace. It sounds as though it is a vibration like one of the exhaust components is touching the frame or suc. It does not make any noise once up to speed nor does it getting any louder. I don't need to get the service done right away. so I was wondering if I should be looking for something like a bad exhaust hanger. It almost sounds as though it a metal brake component rubbing on a rotor. Any ideas would be appreciated.

I had a similar sound. It was the core of the catalytic converter that came apart.
