All of the nuts were super tight. One of them rounded off and I had to end up cutting it off. those flange nuts are very soft.

Then I removed the muffler and went to undo the Y-pipe. Both of those nuts were super tight. I was able to get one loose but the other one started to round off too. So I gave up, before it was to late and would have to be cut off also.

I thought that I could do this job with regular hand tools. I guess I was wrong. I didn't think that I would have to use air powered impact tools to do this job.

So much for ringing in the new year with my new F.I.

When I did my catback, I had only about 5,000 miles on the Z so I thought all of the bolts would be highly cooperative. This was not the case. As you pointed out, the nuts and bolts are amazingly soft and I ended up rounding one of the Y-pipe nuts. This was remedied with a die grinder and we cut the bolt off. This turned the 1 hour job into more than and hour and a half.

For future reference, and I know this but did not follow my own advice, anytime you are working on anything under the car always use 6 point (not 12 point) sockets to minimize the chances of rounding.
