Re: IF you get CEL when removing the cat, what will happen to the engine? (Boostin20v)
When I took my cat off, my motor made insane power for 3-4 minutes and then blew up. I ended up totalling the car and buying a new one...Don't mess with your emissions control devices! The man is watching! LOL...
Re: IF you get CEL when removing the cat, what will happen to the engine? (SkodaRS)
Back in the day, we used to think that removing the cat would affect the power output of the motor, ECU coming into play.
I don't think we had a clue. Only side effect will be the CE light. You will get a Cat Effeciency Low, Bank 1 fault, or something like that, but no negatives on engine performance.
