- 6 sided 14mm socket, 3/8" as otherwise it won't fit
- 1/2" to 3/8" adaptor
- 1/2 ft 1/2" extension + another 1/2" extension to be able to reach out of the engine bay. The key here is to have as few extensions as possible 2x1/2ft would be ideal I guess
- 27" 1/2" breaker bar (the one you can find at harbor freight)
- gallons of pb blaster, wd40 whatever you have
- 3 days
The driver side was what took me longer as it seemed it did not want to come out. Finally it loudly snapped and came off. The passenger side didn't snap, it literally "broke in half" from the torque I applied to it luckily it broke towards the end of the nut stud so I was able to get the cat off.
Side note: the Service manual says those nuts have a torque of 43lb/ft, those demon bolts are NOT like that on this planet.

If you use all impact-rated parts, you can get away with a 3/8th size socket, but good luck finding 3/8ths inch impact rated tools.
I did them all with 1/2 inch drive stuff and didn't have any issue fitting a socket on.
I could literally give you a list of tools I used, as they all came from harbor freight, and you can order all the same stuff.
And the FSM is right about the torque rating... It's the heat that causes corrosion that makes these nuts difficult to get off.
If you drove a car home from the dealer and immediately went to take them off, they'd come right off, no big deal.
