I tried to install my new cat back system today but ran into problems. I bought a nice new floor jack and two more jack stands so I could do this at home. I sprayed my bolts down with wd-40 first. My first problem nut was on the muffler flange.

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.
