Rumblings under my 2008 Corvette

I have a Chevy corvette 2008 I bought from a certified car dealership. I purchased the car with 6,700 miles five years ago. The vehicle now has 17,900 miles. About six months ago I started hearing a rumbling noise underneath the car. The noise is heard when the car is idling or in park position. Can you tell me what it might be? Thanks, R.

Most likely exhaust system, catalytic converter heat shield.
