If your O2 sensors are turned off, but you still have your stock exhaust system off, is that goin to hurt anything. I have been running it like this for a week, but my headers and offroad pipe are goin in tomorrow. the reason I ask is, if the o2 sensors are off already, would there be a way to tell with still having the cats on? I was just wondering if there is a way to tell if the sensors are off already.

Not quite sure what you are saying....the sensors are off, it wont matter if you still have the cats or not. the sensors are OFF. It wont hurt having the cats still on with the sensors off.

i was just wondering if there is any way to tell if they are off. Not sure if my tuner was tuned for the O2 sensors to be off, thats all.

OK i understand now...well the light will probably come on once the work is done.

I would ask the place where you got you tune from. They will tell you if they did it or not.

Ya, i kinda figured that out. I ordered the kit from Brent at Brenspeed. I told him I was gettin the headers and off road pipe, so hopefully its tuned for that. Guess I will find out. Even if its not, will I still be able to drive it the hour home without hurting anything?

You wontbe hurting anything. It is just measuring the o2 levels. The light will come on, dont think you will go into limp mode unless you have some more stuff going on.
