IE Performance Tune and Exhaust setup

Wondering if anyone out there is running an IE tune on their 2.0t. I am looking into running just a test pipe and ditching the cats. Does the IE tune disable the rear O2 sensor ? ie. I wont get a CEL ? If not, does the IE tune eliminate getting a CEL if I use a high-flo catted downpipe ? Anyone with experience please share what ya know :D

I have the IE downpipe along with their CAI and Intercooler no cel multiple scans with OBDeleven showed no O2 errors tuned to IE stage 2. Actually right after I put everything together the first scan did show both O2 sensors error but that’s expected after clearing the codes everything is good.
