Default Exhaust size needed

I am new to C-5 vettes so go easy. I need to know the stock exhaust size for some mufflers I need. I know is either 2 1/4 , 2 1/2, or 2 3/4
but under the car with the tape measure isnt looking accurate. Does anyone know for sure what size it is. Ive used the search engine and turned up nothing.

Default Exhaust

All C5s have 2.5" exhaust system. Some of the pipes will measure a little off 2.5, like around the cats, etc. Some of us go to 3" when we install headers or other motor upgrades.
