Cut cats without throwin a code

[Black96]

hey guys,
My cats are fallin apart and my flowmaster blew a baffel out and i had to cut it off, i dont feel like having to replace the cats for new, but i was wonderin if any of you guys knew how to clean the cats out and trick the o2 sensors or rewire them that it doesn't throw a code?, i know the truck might not pass emissions, but i didn't know if any of you guys have done this and if it still passes, and how to keep the check engine light from coming up. il get a video soon of the truck with only the cats and no mufflers for the sound, it sounds good now!:cool2:

run it how you need to until you can get it fixed, maybe. I dont think theres a way to trick O2 sensors, but you can just ignor it if your sure thats the code your getting.

They do make 02 simulators that trick the computer. You would only want to use these on the downstream, not before the catalytic converter as those control your air/fuel mixture. Do a search. You can find all the information you will need under 02 sensor simulators or sims

yeah there down stream from the cats, i know the o2s up front are air fuel, i just wana clear them out and get the codes off so i can run it thought emissions, even though my buddy will be doing it
