Wideband O2 location
I just got my WORKS custom DP (I had them put an O2 bung before they coated it).
Anyways, when I went and picked up my DP, I thought the place they installed the O2 bung was a little weird (look at pic), but they said thats where they always install the O2 bung. I want to know if this location is bad. I don't care if I have to change the sensor every once in a while because of heat damage, I just want to know if I'm gonna get correct readings from this location.

Honestly I wouldn't have put it quite that close as most widebands freak out and give errors and/or produce inaccurate data when the sensor is overheated. You might be OK but you're close. Placing the sensor 2 feet or more from the turbo usually avoids those issues. I'd estimate you're barely over a foot from the turbo by looking at that picture.
Placing it towards the rear of the downpipe makes it easy to get to and provides accurate readings.

I noticed the spot they mounted the bung makes it so you can un/install the O2 w/o removing anything (DP, under plastic, etc.)

Anyways, any more opinions, maybe from someone that has their O2 mounted like mine will be.

the sensor should be located at least at 9 oclock or higher.
inovate sells a cooling piece for the sensor, or make one from sheet copper. something like a three or four inch square sheet of copper sheet (drilled) that fits between the bung and the sensor. same idea as that funnel the vet puts of a dog's neck, only in this case you don't want to incase the sensor you want air to flow over the copper sheet.

Just emphasize these points. You need the sensor pointing as close to straight down as possible. This is so condensation will not be trapped in the sensor...which would expand with heat and break the sensor.
That location is (arguably) borderline too close to the engine, but as stated you can install a heatsink to be safe, and it may even be fine without one. Remember that excess heat will not only cause bad readings, but could also damage the sensor...
Best of luck!
