Installing O2 sensor bung: where?
I need to have my O2 sensor bung installed sometime in the next week or two. Where precisely on the pipe should I have them weld it? By that, I mean driver's side or passenger's side? How far forward of the cat, or conversely, how far from the engine? I have an Autometer sensor for the Cobalt A/F gauge, if that matters.

RE: Installing O2 sensor bung: where?
Technically it should be welded in a two o'clock position to avoid ondensation buildup on the sensor.
I'm not running a sensor continuously (just using it for tuning) so we just welded on @ a 6 o'clock position.
There is only about 4-5" between the front of the cat and the header flange....so it won't matter where you put it. Drivers side has a bit more room.

mine is on the passenger side, maybe 4 inches in front of the rear O2 sensor, same angle as the rear O2 sensor. i dont have cats, idk if that makes a difference or not.

RE: Installing O2 sensor bung: where?
If you have the stock manifolds and H-pipeyour O2 sensor for the widebandhas to go on the drivers side on the h-pipe in front of the driver's side catalytic converter. There is an upstreamO2 sensor already on the passenger's side up there. The driver's sideupstream O2is in the driver's side exhaust manifold. So there is a small section in front of the cat where you can install it without even dropping the pipe.
Since it has to go in front of the cats the drivers side is your only choice with stock exhaust. The wideband sensor should always be asclose as possible to the manifold or header so the sensor is properly heated for calibration cycle. If you have headers there is more room to weld a bung. It still has to be in front of the cats if you are running cats.
I have had the Cobalt wideband in my car since it was released. It works great.

Well since I have a cat-back system and stock everything else I know where to mount mine! Thanks for the details!
