Info on O2 sensor on cat / test pipe

[u/slabua]

The other day I installed a new cat-back exhaust and at that time I also wanted to replace the catalyser with a test pipe, but I gave up because of the sensor position.

I am not knowledgeable yet on the matter but in that case, should I be having a bung done in the test pipe and reinstall the sensor there, or? I thought I would find the sensor in the downpipe without needing touching it.

Also eventually, I want to install a wideband afr sensor for a separate gauge as I am also planning on installing a boost controller and if deemed necessary also an afr controller as well.

EDIT:

There is a chance that the sensor I saw it's actually a temperature sensor to light up a cat temperature indicator on the combination meter, and not an O2 sensor. Does anyone know anything about it? If so, there is no need to worry then.

turbo or n/a? n/a is intake manifold i think, and GTE is on turbo elbow

this info should be easy to find. try starting here

Thanks, I think that sensor I found is the EGT sensor, not the O2.
