02 Sensors

**GottaHaveLS1** · 10-29-2005, 10:25 AM

When i got my TA about 3 months ago i replaced the 02 sensors within the first month. I'm thinking of replacing the full exhaust without cats and therefore i would not need 02 sensors, i would need simulators. Is there any value to a used and functional Bosch 02 sensor?

I would say yes but I don't know how much.

you'll still need the pre-cat o2's...so just put the new ones up there. If you already have new ones up front then try to get your money back from where ever you bought them.

You will still need sensors up front (extensions with headers). You can either buy simulators for the rear o2s, or tune them out of the car. I did the latter. As far as buying a used o2, they are not that expensive new, just buy a new one (unless it's your buddy who's used it for like 50 miles).
