cause it sounds like a Honda and does nothing for performance (and in fact, it's a long argument, but the consensus seems to be that since BMW designed it as a closed system, it's best stayed that way without leaking air outside like a bov does). Believe me - a number of people have been running high boost with no cheesy "kssh" and it's been fine
