It got me digging and I spent some time finding the stock part number for the X5 50i / M50i downpipes and what models share the same part numbers. What I found is extremely good news. Here are the part numbers and compatibility charts.
What you will notice is that the 2019/20 G05 X5 50i & 2020 X5 M50i share the same part number downpipe as the 2018 550i xDrive and 2020 850i xDrive. I know for a fact there are downpipes for the 2018 550i xdrive, so it appears from this chart that those will fit our vehicle. I am really close to pulling the trigger on a set.

Thanks for sharing.
I have ARM M550i catless downpipes on my 50i. Perfect fit. Also have the ECU tuned by DME (stage 2). 622 HP and 660 TQ at the crank. I'll be posting something in the coming weeks with more details and information.
