i have a mapp gas plumbers torch, works great for things like that.
Gets hot enough to get a mild glow on the exhaust.

Old trick i use to do was to do a short sprint on the freeway for like 10min.
Then jump under there and pop the o2 sensors loose/off.
Trick there was to get some good load, load being the important part for them getting actually hot.

The operation was a success and the patient is resting comfortably with four new O2 sensors.

No big glitches I did use the aerosol kroil on top of the WD40 and the pipes on both sides of the cats were hot when applied. Frankly, the clips and push fasteners were as much fiddling as removing the sensors themselves.

The new sensors came with anti-seize on the threads and I chased each bung’s thread with a little adapter that came with my cheapo sensor socket set, so hopefully when the time comes and they need replacing again (which I assume will be sooner than this go around), it will be similarly painless. Actually the biggest pain was the sand getting knocked off the frame and falling into my eyes. I know, I know, safety glasses...

That is all... :)
