The same Supersprint micro cat set was tested on US Spec M5's and did not work. I checked with my contact in Germany and he informed that the Euro Spec emissions sensors are not as sensitive as the US spec M5's. My guess is the micro cats were tested on a Euro spec F10 M5 which did not get a CEL.
The CEL from "increased emissions" on the US spec M5 does not cause any harm at all. All you will get is a light on the dash letting you know that there is a problem with the sensor or cats. Once a real tune hits the market you can simply shut the light off.
