Here is a pick of what it looks like off and the sockets I used to break them loose. I used the larger size Ratchet and my hydraulic jacks extension Pole have someone help to hold the socket in place while the other breaks it loose. Good luck. make us Proud... the socket is a 9/16 high impact and so is the swivel, you need to use these types because the standard ones will break.

It would help to grease the bolts before your try to take them out

I used a Crow's Foot to take out the hard bolts

getting the cats off was a real PIA hopefully the lth install won't be as hard.

I've noticed that good deal of the 350HR's and 370's seem to have impossibly torqued cat bolts. I've ran across some that were completely cross threaded, luckily I was able to just remove the stud and bolt as a whole. Not sure what's going on at Nissan's factory these days!

I just saw this thread and it could be worse as I had the same problem.
I rounded mine and have rounded nut sockets to try out. Will try and bang the socket on and have my cuzn hold the long extensions in place while I use a long floor jack handle method. This time Ill start with the stubborn bolt.

First time I did the install, I got the passenger side off and FI Hi flow cats on and 2 bolts on the driver side off till I rounded the nut...I had to take everything off and reinstall......I still havent gotten to it and its been a month as I only got weekends to work on my car and Ive been busy..

is the header flange also threaded? if not maybe i can just try and shear the head of the bolt and pull it out
