The hardest part for me was disconnecting the drivers side front O2 sensor. Took me like 20 minutes of painful concentration lol. It's so tight up in there.
I sprayed mine with PB blaster the night before and then again about 15 minutes before I started. It was tight, but came loose with a prob. I was most scared with the bolts connecting to the manifold. AM sells a passenger side manifold outlet gasket. I recommend getting one when you go to button up everything with the new midpipe. You can do it, just take your time.
And chock this rear wheels so she don't roll on you! Good luck.
