Long tubes/offroad y pipe...can I drive without rear o2s and o2 simms for a little

Not sure if they're going to come in by the time my headers/ypipe are installed...besides the SES, is there anything bad about doing this? Am I going to hurt anything?

I ran very rich without them. I'd get the simms or get it tuned out within 6 months.

Thats strange, the rear O2s are used only to monitor catalyst efficiency. They dont have any control over the fuel.

It wont hurt anything to drive without them. As stated, it will turn on the SES light.

jason, if you feel like climbing under my car, you can have my sims. i bought them and then ended up getting a tune anyway. been on little over a year, 2k miles.

if you want them i can arrange to have them pulled.
