This is a genuine BMW muffler, part number 18 21 1 344 531. The number stamped on the part is 18211344531; BMW's catalog files it under the short number 1344531. You will find it on our Exhaust shelf, under Other Exhaust system parts.

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

BMW draws it on the Exhaust system (18_0302) diagram. It weighs about 7.6 kg (17 lb).

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