Looking at getting a de-cat for my evo 8, I currently have a high flow cat and an 02 sensor already before the cat hooked up to a AFR Gauge, now im wondering with the new de-cat test pipe this has a 02 sensor hole in it already as seen in the picture below. would I get a CEL light if i just capped it off with a threaded bolt.

Looks like you are already set w/the down stream o2 sensor & your wide band guage hooked up. Yes, get a standard plug for the test pipe & get that installed

One thing that comes to mind is that the engine tune is likely setup w/the HF CAT & removing the CAT will change your exhaust flow. Consider a re-tune?

If you had already deleted the downstream narrowband 02 sensor, then you will be fine.

Like MinusPrevious said, you will need to tune for a test pipe.
