Default O2 question

My headers are on their way. I'm one click away from ordering my catted true duals.

The sight says basically, even though there's high flow cats, there's no o2 bungs for the sensors; which I understand, we have 1 sensor and now 2 cats.

So my question is, if I plan on tuning out the rear sensor anyway, can I just unplug the harness and tie it up out of the way?

I considered buying an o2 bung and having it welded on, and keeping the sensor bolted into at least the passenger side jic TX goes full visual.

T.I.A

Yes you only need the front two on the header collectors...tune the other two out...

There are two in the rear? Never really looked.

Thank you for the response

Stock cars have four O2 sensors; two pre-cat to determine AF, and two post-cat that only check catalyst efficiency. You can tune the rear two out since they don't affect anything, but the fronts have to stay in.

Yeah, it was the rear I was worried about. When they come in, I'll have the bungs welded in and get it set up right....for appearances at least.

Thanks again
