On mine the down stream sensor wire was too short. I took the risk of cutting and splicing using solder and heat shrink tubing. I did look into longer O2 sensors from other BMWs incase the increased resistance caused a CEL. Never followed through with it as I didn't have any issues.
I have had my DP w/ cat back installed for over a year now and passed inspection with emissions without any issue in NH in September of last year.
