Wide band on stock catalytic converter

You'll need to find a place upstream of the cat to weld in a new bung for the aftermarket O2 sensor. The car needs the O2s that are in there now, so you would need an additional sensor for an aftermarket gauge.

That location might end up having to be on the header. I don't know if there is enough room on the stock cat to weld that bung in.
