Yes, the top bolt of the cat flange should have a welded nut. The bolt however will back out just fine. The bottom two bolts you will spin the nut off as the studs will stay in place, bottoms are pretty easy to get at. Takes some clever arm routing but over all pretty easy. I also sprayed mine with WD-40 the night before just in case.
