Genuine BMW part 18 12 8 521 881: Exhaust flap. The number stamped on the part is 18128521881; BMW's catalog files it under the short number 8521881. You will find it on our Exhaust shelf, under Other Exhaust system parts. It supersedes the older number 7716477, so a part carrying that number is the same part. BMW has since replaced it with 8546552.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on the Exhaust flap (18_0836) diagram. It weighs about 560 g (1.2 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
