Fault Codes after changing cat-back exhaust
I will be changing out my stock exhaust for a full Meisterschaft cat-back exhaust on my F10 M5 soon, and was wondering if this change would trigger and fault codes?

Not sure it would cause a fault, but did you plug or reconnect the vacuum line?
It sounds silly but I've heard this can cause issues if not connected or plugged.

make sure you plug your old vacuum lines or you will have a boost leak and the car will feel severely under powered. I know because it happened to me on my FI exhaust.
