Exhaust pipe diameter 1999 Accent

So the flex pipe on my accent is rotted through.
I looked around and found that I can order the flex piece but I have no idea if the exhaust pipe is 2", 2.5" or what

Been so cold and rainy where I am past couple weeks I haven't gotten the chance to go underneath and try and measure.

So if anyone knows this information it would help me out so I can order the part sooner than later
