Very enjoyable 44 page read.
Thank you for all of the time and effort you have put into this thread.
I was curious if you ever figured out the check engine light issue you were having with the downpipe and the 2nd O2 sensor? You may have said in previous posts, but it took me a few weeks to read through everything so I may have missed it.
I have a PLR catless downpipe and PLR front pipe and was finally able to get the rich fuel code to go away after trying multiple different defoulers with no great success until I tried this one off of ebay, using the medium restrictor plate.

I put it in to start with, reflashed, and it came back with in 20 miles, checked the codes, nothing actually showing, tightened down the sensor and defouler. Kept driving, and it went away, and has been gone for over 400 miles.
If you already solved this issue, sorry to waste your time, I just was excited to get rid of mine, and remembered you were having issues with it.
