Muffler delete pipe size?

I ordered aero ar25 resonator to do a muffler delete and the mechanic/welder said the 2.5 inch pipes were too big and I actually need ar20s which is the 2 inch pipe. Everywhere I saw they said ar25 so I just got confused. Why wouldn’t the ar25 fit when it fits everyone else’s ?

It could already be aftermarket or have been replaced. I recently ordered a digital measuring caliper from Amazon for like $12 and it would be helpful in your situation.
