In New York all OBD2 cars just plug into the diagnostic port no "sniffers" here. Once I get my oil burning problem solved I will get a high flow cat.

Lol, that'* funny that you say that.
1. A PCM can tell if the cat is there or not.
2. NYC still uses sniffers
3. Being a NYS vehicle inspector, I can tell just by tapping on a cat if its gutted or not. So stop with the bullshit and stop offering illegal advice.

It doesn't know per se, but if its gutted or missing the PCM can tell something is wrong via the downstream O2 sensor values. This will trip a code eventually.
