o2 sensor simulators

I have an 05 f150 with the 5.4 engine. I replaced my cats with magnaflo high flow cats, replaced all the my o2 sensors and monitors with brand new ones. I still get a check engine light saying my sensors are reading bad. My question is, does anyone have any info on the o2 sensor simulators, what part numbers I need for my truck, and where I can order them. My state does not require inspections so that's not an issue to me. Thank you for the help.

This! But to the rear O2s only. Not the front

Front adjust your A/F ratio. Altering the exhaust flow to the fronts will cause them to read wrong and throw your A/F ratio out if wack

What exact numerical codes are you getting? If P0420 and/or P0430, that mod to the REAR sensors should take care of it.
