First off, I just want to thank, who ever previously worked on my Miata, because everything seems to have been done improperly. The latest. Not using Anti-seize on the O2 sensors.
Smart.
I would be enjoying my new exhaust right now, but instead am having to wait until I get new O2 sensors because removing them will be impossible without damaging them.
Thanks.
Do things right, or don’t do them at all... was a phrase this Mechanic had never heard before.

Every O2 sensor I have ever installed came with anti-seize in the box. Usually copper.
You can’t use Kroil to seep in the threads?

Been there, ended up cutting up the exhaust until I just had the sensor and the surrounding threads in a vice, carefully realeased the stress around the threads with a chisel. Then heat+force. It took a long time.

Why can't people do this? Its not like anti-seize is expensive or perishable, I've had the same bottle for a couple of years and use it on nearly every bolt. That stuff goes a long way...

I’m not familiar with Kroil. I was having my local exhaust guy do the install because I was afraid of this kind of thing happening. He said he tried everything; even heating it up. He’s been in business for 30 years, so I just took him at his word

I hear ya! For me I had to replace my 02 sensor’s. I couldn’t take the one before the CAT off while it was on the car due to it being seized. I ended up taking off the down pipe, cutting the o2 sensor up, chiseling the interior bits of it out then cutting the threaded portion from within. Yeah much much fun!

PB Blaster, Kroil...when there’s a will, there’s a way. Just put a box wrench over it, tap it with a hammer a few times, heat, spray, repeat.
PB Blaster has saved me more than once with stubborn bolts.

Anti-seize is actually included with Denso oxygen sensors.

Yes, it is a little known fact. You should always use ANT-Seize on your O2 sensors.

My mechanic friends keep handheld size torches in their roll away boxes for exactly this reason.

Yep... that’s why I like to work on cars myself. With cars I’ve owned/seen, the improper work that I found so far was:
1. Wrong motor oil being used (I’m 90% sure of this based on the Mr Lube sticker and the condition of the oil that came out even though it was supposedly changed 4000km prior)
1a. Oil drain plug waaay overtorqued.
1b. Using Locktite on oil drain plug.
1c. Overtightening oil filter
1d. Not removing plastic on oil filter before installing.
2. Improperly torqued wheel lug nuts (very VERY common... even if it’s a dealer that has done the work). Most recently... not enough on driver’s side and too much on the passenger side.
2a. Cross-threaded wheel lugnuts that must have been done by some airgun-happy mechanic.
2b. Trying to sell a car with missing wheel lug nuts (even though it was “certified and etested”)
2c. Installing a non-automotive nut of a different size (but similar thread) to replace missing wheel lug nut.
3. Door trim that was installed before paint was fully dry... which in turn caused trim to fall off taking the paint with it.
3a. Improper body panel/dent repair where the paint the paint bubbles up suspiciously fast after only one winter.
4. Shitty amateur wiring repair that would start shorting out and blowing fuses the next time it rains... likely because the person who worked on it was cheap and lazy.
5. door trim that was reattached at some point... but not attached completely straight.
6. Tie rod replaced and no 4 wheel alignment done after.
7. Only 2 of the 4 rear license plate bolts installed leading license plate to rattle.
8. Having different tire pressures to hide the fact the car has an alignment issue (old mechanic trick... avoid used cars being sold by mechanics you don’t know).
9. Not using anti-seize when swapping out spark plugs
9a. Not using dielectric grease on electrical connections.
10. Installing directional tires so that they will be turning in the wrong direction.
And that’s just off the top of my head. And this is all very basic stuff that any professional should know. And they probably do know most of the time... but they just want to do it quickly and bank on the fact that most customers won’t notice.
It makes me want to do as much myself as possible.

Agreed. Neglect and laziness are lowering the quality of used cars. I've still got some work to do on mine.
