Full BCS here too with sports cat, awesome on full chat and burbles well stood still. I reckon it would defo pass track days, my FRS was louder and only failed Donnington 98db.

Would that pass a track day noise test?
If all you did was change the mid pipe (on a 140i) then yes.

If you decatted and went for the full BCS cat back, I'm not so sure.

If anyone wants a video I've got a full system with sports cat on my M135i, PM your number and I can whatsapp you some vids. It's bloody epic, genuinely pretty quiet when pootling around town. In fact my dad took it to work and barely noticed a difference other than a slight hum at 70, but the full boost noise is pretty loud, and makes the sound much more aggressive. They aren't cheap but they do transform the car.
