Can you tell us what code the ECU is logging? Does the car have any modifications?

Just get a tune and down pipe! Problem solved.

If you have a catalyst efficiency code then it will most likely be drivable, worst case the cat material can cause a misfire if it becomes dislodged from the pipe. Will obviously give a different fault code in that case.

Worst case is a piece of the cat breaks up and gets sucked back into the turbo.... Slim but possible.

If the car is stock get it get it replaced potentially under warranty. https://www.consumerreports.org/cro/magazine/2014/11/how-one-driver-saved-8-000-on-emissions-repair-for-his-bmw/index.htm
