01 View BMW DiagramSee this part on the official exploded view→This is a genuine BMW exchange exhaust pipe catalyst, part number 18 30 7 525 549. The number stamped on the part is 18307525549; BMW's catalog files it under the short number 7525549. You will find it on our Exhaust shelf, under Suspension parts exhaust. It supersedes the older number 7521988, so a part carrying that number is the same part.
It fits every E46 body style (316i, 316ti, 318i and 318ti, 2001–2004), with the N42 or N46 engines.
BMW draws it on the Catalytic converter/centre muffler (18_0452) diagram. It weighs about 13 kg (29 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
