Well the post cat sensor sends information to the PCM on how well the cat
efficiency is performing . No cat, poor performance, light on. Well who am I to say your light is on.
BTW you can buy a sensor to plug into the 02 sensor and the PCM still thinks there is a cat installed. I would never do it though.

I will just leave it alone it doesn't turn the check engine light on and it still runs great no problems i acutally think it running a little bit fatter helps it in the long run
