Default O2 Sensors....??

On my '18 that I recently purchased, I just got it up on jack stands to install the Invidia Gemini cat back system; noticed that there are only two O2 sensors, which are post-cats; the pre-cat O2 sensor bung has a bolt in each one.

Is this OEM?..or did the previous owner remove them? I have looked around for open connectors or an end cap...have not found anything yet.

What is going-on here??

Thanks

Should be 4 O2 sensors total. 2 pre cat, 2 post cat. I would check to see if the car has a tune.

Ya know....there are days when I seem to leave my brain in the shower.

Just ignore my original posting above.

Yes there are four O2 sensors....if I had looked a bit higher-up on each cat I would have seen the pre-cat O2 sensors....oh bother!!

What I saw was that each cat pipe has two sensor bung locations....I was seeing the lower one with a bolt in each one.

Oh bother!
