Best way to check if cats are plugged is going to a muffler shop and have them take a infared reading on them. Only takes a couple of minutes.

Or use a vacuum gauge connected to the intake manifold.

No it's off I have spacers on the O2 sensors so it fools them into thinking its still got the cat so it reads proper and its runs clean.

Well no, you tricked the sensor, so it's not really "running clean" at all.

The vehicle is just reporting it is (based on false input information).

If you had the sensors installed properly, it would report an error.
