Update

I installed the restrictor plate that is completely closed on the mid pipe and ran the car another complete drive cycle and I am still getting both o2 sensors as INC.

I bought the hand held that has the emissions reading and I still can't get the o2 sensors to read ready.

I have thrown zero codes with the coyote so that's out of the question.

The guy at the stealership kept saying it was the axle back but that makes no sense if it's after the o2 sensor.

Do y'all think I can dump the axle back and run it seeing as I don't have the stock exhaust anymore? That's pretty much my only option left other than replacing the o2 sensors that Ford said was working.

It's not the cat because I have no codes and the cats coming back as ready on emissions.

Welp....open to suggestions as always. Pretty much at a point where I want to just pass inspection...and trade her in for a 350.

Thanks,
Jayson

I don't see how cats can show ready if o2s are off. The rear o2s read catalyst efficiency so if one is not ready they both should be not ready.

does the car have long tubes by chance?

Nope haven't touched the headers.

can probably get for cheaper, $75 maybe? there are some stock mufflers for $50 on there also. good luck

if you have stock midpipe I'd start there before buying anything else. That is the most likely culprit for bad 02 readings.
