Should I put in a new O2 sensor?
I am getting my new exhaust in a couple of days. It is RB header, pre-silencer, and cat-back. I was wondering if I should put in a new O2 sensor with the system? I still have the original one in the car now. Also how can you tell that one is going out or is not working right? Thanks

If your gas mileage stinks, then that is a sign that it is bad. You are better off replacing it since it is original to the car. They are pretty cheap and easy to replace.
