Default Stock Exhaust size clarification

Hey guys I have a 2012 5.0 and I was trying to get some clarification on the stock exhaust size. Im going to cut the exhaust after the cat back flange but before the resonator. Is this pipe 2.5 inches or 2.75 inches? Im going to run 3 inch pipe from there to a muffler and then of course the tailpipe .

perfect so if I cut the exhaust after the flange but before resonator I just need a 2.5-3 adapter then a 3 pipe to my muffler of choice (MF14419) then I will rage my corsa 3 tailpipe after the muffler...
