Happy to stand corrected, but I’d go for inside red area of attachment.

Saves removing heat shield?

Have you done that? Does the sensor work that far from the CAT?

Ive a decat header that requires a O2 sensor hack

Ok because from what I read it can’t be too far from the CAT. something to do with the readings whilst really hot.
