Probably this has been asked already, but searching for "carbon exhaust" did not really help (too many threads about carbon breaks).

From time to time I see the attached picture in the header.
What is this exhaust and how do I get it? By the car color it seems as if it is a part on the M4. Is it also available on the M3 (already)?
Which option do I have to tick if it's not part of the individual program... or is it even standard?

Thanks! (and sorry for the noob question!)
