Update:

Injectors got here and I was about to replace all 6. Before-hand though I wanted to double check my downpipe job before I replaced them, as, all of this started after replacing downpipes.

Turns out the BMW master technician I had with me (sarcasm only slightly intended) swapped my O2 sensors front to back and back to front. Swapped the plugs and no symptoms and beautiful cold start idle and hot start idle. 100% fixed. I'll be swiftly returning those injectors, clips, and seals and saving almost 1400 dollars. Turns out my intuition was correct. I didn't really believe this was an injector issue. Dodged that bullet for now!
