I used some leftover Valvoline Max Life (Nissan Matic S compatible) in the red jug. I'd imagine most any ATF will suffice when mixed w/ Acetone. I used Acetone from my wife's bottle that she got at Sallys Beauty supply for nail polish removal.
Got the o2 sensors out without incident 18in breaker bar. Got the cat to tranny brace bolts off and cat to y pipe bolts off. Going to let the 6 total 3 ea side cat to header bolts set over night.
I was able to get the demon bolts off without any penetrating fluid. I couldn't figure out how to get the can of PB down there to spray. 24" breaker bar was enough to snap the bolts in half.
For the four lower bolts, I soaked in PB for 20 minutes or so. This was much easier because I had the car on a lift. Same breaker bar broke them free without any issues.

If I were to do it again on another G/Z I'd use a syringe, that ATF/Acetone Mix works the best but hard to isolate it to just the bolts when using a spray bottle.
Finished.
5 hrs start to finish.
Hardest bolt was driver side bottom due to space. Very cramped.
Thanks to all you for the help.
Much appreciated .
Do i need to reset ecu or leave it?
Car pulls very hard now as is
Sorry to resurrect an old thread like raising Lazarus from the dead, but thanks for the guidance, Brad. I feel fortunate that living in Arizona with an AZ car, I didn't have any rust to contend with. PB Blaster soaking overnight worked for me and although I bought one, I ended up not needing the universal impact joint. 1/2" breaker bar with jack handle slipped over it + a 12", 10", and 6" extension. Took both bolts downtown to Chinatown.
So quick update on my experience. Back on 7/20 (see my post above blnewt's), I had some spare time and some motivation, I decided to just try and loosen the demon bolts on my car. My FI RHFCs weren't scheduled to be shipped for another month, but I figured it couldn't hurt to at least loosen the demon bolts in the meantime. With a lot of effort and a jack handle on the end of a breaker bar, and pushing my body weight into the tool to ensure the socket remained evenly seated on the bolt head, they finally gave way.
Fast forward and yesterday I removed my cats ahead of my RHFCs arriving tomorrow. I thought the hardest part was over now that the demon bolts were at least broken free. Well, they were almost as hard to turn as back in July and I ended up snapping both of them. I'm not sure how that happened. I definitely felt them break loose back in July and yesterday it felt like I was doing the job almost all over again.
What tool or remedy kit do I need to buy in order to be able to back that broken bolt shaft out of each flange?
Sorry to hear of that, bolts should only be used once, and when new ones are installed you should use copper-based anti seize on the bolts. Once you tightened them back up and high heat is applied combined w/ condensation you get another rust bomb to try and break free
Probably need to have them drilled out now or maybe a torch w/a lock wrench perhaps???
Sorry if I wasn't clear; definitely did not re-use these bolts. I had simply broken them loose back in July, then left them that way (mostly-tight). Then came back a month later and tried to loosen them all the way and they snapped.
Oh, yeah, that's a bad situation but quite a few around here have had to go to the nuclear option aka the torch. G/L hope it doesn't set you back much.
