I just helped my buddy install a mac prochamber on his GT and now i gotta know what to do with the stock O2 sensors. I installed the stock sensors onto the new prochamber and was wondering if they will do the job or will i have to change them out for something different. The engine light is on which i knew was going to happen, but is the fact that the car has no cats going to screw up the air/fuel system with the O2 sensors.What did everyone do when they took out there cats?

The extra O2 sensors need MIL eliminators, or need to be turned off using a handheld tuner or with a custom tune. It won't mess with the A/F ratio (unless the computer puts it into limp mode), because the rear O2s are just to check catalytic converter efficiency. The good way to do it is with a handheld tuner or a custom tune. MIL eliminators will work, are cheaper, but are also prone to failing.

Edit: I forgot to answer, YES you use the stock O2 sensors.

no cats will make the light come on i removed mine and the light hasn't come on yet, so i don;t know. but yes removing them will make the light come on. i don;t know where to get the O2 sensors from but i am pretty sure they do make them

just get aint-falouers you can get them at pep boys, they screw into your 02 sensor location it will cost you five bucks tops, buy four drill out two of them and screw them into the top of the non drilled out ones, then place the non drilled end into the 02 sensor weld on the exhaust, then just hook up your 02 sensor its should look long but it saves you money, i used to do it on my 350z and 383 camaro

i have never gotten a code with them
