I figure since I cut my exhaust out to install my 4L80E, I'd go ahead and mount my O2 sensor for my wideband.

So, what side should I mount it on and where should I mount it? Also, should I remove my catalytic converters and rear O2 sensors?

Here's my exhaust.

 

I would mount it as close to the front as possible, and in front of the converter. It is suggested to mount it on the top of the pipe anywhere from the 9 o'clock, and 3 o'clock position as moisture will settle in the bottom portion of the pipe, and it will reduce the life of your sensor.

 

Sweet, thanks! Does it matter if its driver's side or passenger's side?

 

I had mine a little too far from the front and i went thru sensors. Moved it into the stock o2 spot and it has been golden since.


You have a 2000. Put it on the drivers side, where that famous #7 cylinder is.

 

Most O2 sensors call for 15 degrees over horizontal when mounting. Like said above, it wont collect condensation that way. I have mine on the drivers side.

 

I did it right after the converter, didn't work tbh reading was offset by >0.3 ±.

Best place after the collector. As oakley6575 said 15 degrees is the best mounting place, you don't want condensation all over it.

 

^^ You want it before not after the catalytic converter




Just re-read.. think your second sentence was a typo.

 

Correct, I had it after which was wrong.

 

i just had one installed my tuner area47 said you get a better reading before the converter. ididnt know about the angle. mine is on the side of pipe.
