Can anyone answer a 02 sensor/ cat question?

[Mark Nunzi]

Im looking to gutt out my cats . My inspection calls for safety only butt i know if i do this my check engine light will stay on. Does anyone know where i can pick up dummy 02 sensors, and will this improve flow as to high flow cats???

You can have the O2 sensors turned off.

or

you can shut them off with a hand held tuner

or

you can have them shut off if you decide to get a dyno tune

If you take the two small pre-cats off you might get an 02 code but if you gut or take off the bigger rear cats off you will not get a code. I removed the rear cats and no problems and my Borlas which sounded a little better than stock are growling now. :burnout:
