I've been reading forums for about the last hour, and apparently there is something mysterious about BMWs lol. Sounds like everyone who has ever tried to put on an aftermarket cat had no luck whatsoever, and they continued to throw CELs and have problems until they used a direct-fit cat. It also sounds like everyone who replaces the cat replaces the 02 sensors also. So if I'm not mistaken, the whole project can be done for no less than about $400. So basically, since I know my car will run and all it needs is a new header ($150) unless I get about $250 and the BMw, the trade is not really worth it. My Civic could use some body work, but it will still run no matter what. The BMW sounds like it will give me more trouble than the Civic. Any new opinoins?
