Need to know a nut/bolt size for the exhaust

for where the cat-back meets the H-pipe (through the flange there). Putting the Steeda catback on next week and I'm expecting the old ones will probably have to be torched/cut off. Guessing it's a 1/2" or 5/8"?

No one has ever replaced these?

I haven't the slightest. If you think it needs to be cut off, do it and take the nub to a hardware store and test it.

I just replaced my midpipe, I got new bolts from tailors (after busting 2 of the stock ones) and just put them in the old holes..
