At least you can measure that EGT1 in both cases after returning from warm up drive. I point to EGT 1 is it is the precat temp.

Yep.
Waiting for DDE to return in mail while I finish my WM install. But, I did wrap the pipe with 2" at 75% overlap. The wrap was $18 on Amazon for 2 rolls, so I figured it was worth a try.
Prior to this, I'd say the unburnt hydrocarbons were an 8 on a 1-10 scale for unpleasantness. But, that was on an ABC deleted car without appropriate tune. For some unknown reasons, my car drove home with an all new exhaust, fullly ABC deleted, and no limp mode resulted.
I will report the smell once everything is back together, by adding to this post.
Summary: - Car was illiterate with iaknown's turbo-back exhaust with new oxidation catalyst, but with stage I tune.
- Smell was 8 of 10 for unpleasant unburnt hydrocarbons
- Prior to abc delete, EGT's were always 190C idling, never more than 4xxC driving. No EGT data available post-delete, yet.
