Damn there are some pissed off people here

Anyways I didnt know the ecu did that when the check engine light comes on...

Basically it just prevents the car from polluting too much in this situaiton? I mean I dont see what else would make the light go on immediately after drilling my cat besides high toxin levels... the engine is fine.. damn hippies

Well guess im gonna be even more anxious to get my new cat

Is it possible to just remove the rear sensor till my exhaust is legal? Could that get the engine light to stay off and keep the ecu from f'in with the engine power?
