From what I can tell it needs to go behind the narrowbands and at an angle meaning not perfectly horizontal? Passenger side or driver side better or behind the x? I don't have cats.

Here is where I placed it with cats on a stock Z06 exhaust. Driver's side can be right at the O2 sensor. I am on a vertical run. If the run is horizontal like LTs, then 10 or 2 is the best place. 6 o'clock would be the worst. Don't go too far downstream as the AFR becomes distorted the farther away you get from the exhaust event. I did driver's side, but no difference if it is on passenger's side, just where you plan on the wiring to run. Driver's worked out better for me. I also did a stock LS3 exhaust, very similar.

If I'm doing it on the car would 8 o'clock be good?

You have to work with the clearances you have, of course; but, anything below 9 & 3 means the tip of the sensor is subjected to more sediments and moisture. Over time the sensor will deteriorate faster, fastest at 6.

gotcha, do you put anything on the threads when you put it in?

BlindSpot

No, nothing. Dry. Don't overtighten

Thanks

I've always used anti-sieze on things threaded into exhaust. Use it sparingly.
