Wideband A/F guage

I was wondering that since my rear O2s are turned off, could I use one of t the bungs for a wideband O2 sensor, or is it too far down stream. I do not have cats at the moment. Thanks in advance.

Most widebands will tell you in the installation instructions where they prefer to be placed. Like 18-30 inches downstream for example. I think that second bung may be too far. I had one welded in a few inches before my first o2 sensor inside the header collector, and slightly offset so it didn't block the airflow of the stock one.

It only cost me $40 for the weld job.
