Anyone else with excessive carbon on exhaust tips?

On our F25 I spent 30 minutes and two types of metal/chrome polish trying to remove the baked on black carbon on the end of the exhaust tips. It would not come off. I have never experienced this problem on any of our other 3 BMW's.

Is there something about the twin tubo 4 banger? Does it run rich? I suspect an issue of some sort but do not have a CEL. Will have to take in for the shop to scan for codes I think just to be safe.

Anyone else notice this issue?
