O2 sensor question

[Elevated 2013]

I recently got JBA long tube headers installed along with a JBA catless y pipe. Of course I got the check engine light to come on after the install due to the cats being removed. The shop that tuned my engine afterwards turned off the check engine lights for the downstream/post cat oxygen sensors and I haven’t seen it come back on but I know there are codes present for those sensors. My question is, has anyone tried to install simulators or dummy O2 sensors in place of the downstream O2 sensors so that there are no codes? If so, what worked and what didn’t work? TIA!

If your sensors are still installed throw these in. M18*1.5 Check Engine Light Eliminator Adapter O2 Oxygen Sensor Spacer Adapater Isolator Check Engine Light CEL Fix Extension, 45mm length (2Pcs) https://www.amazon.ca/dp/B07GYJP9X9/ref=cm_sw_r_cp_apa_i_diBaEbC1XS8C1
I have cats deleted on mine and the truck is tuned I never got my 02 sensors programmed out I just used these without any issue at all.

I assume you used 1 on each side? I just saw a couple of videos where they were stacked so you had 2 on each side. That’s why I asked.

Yessir just one per side. I almost think stacked would give you an insufficient cat flow code. [emoji848]
