Genuine BMW part 18 21 1 178 300: Bracket. The number stamped on the part is 18211178300; BMW's catalog files it under the short number 1178300. You will find it on our Exhaust shelf, under Other Exhaust system parts. It supersedes the older number 1178447, so a part carrying that number is the same part.
BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.
BMW draws it on 12 diagrams, among them Exhaust Pipe Front (18_0105) and Exhaust Pipe Front (18_0106). It weighs about 175 g (0.4 lb). It also comes in BMW kits Set Mounting Parts Pipe 42mm (9057721) and Set Mounting Parts Pipe 45mm (9057722).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
