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
