2003 E53 4.4i Catalytic Converter Replacement
 

Hi All. I have a bad catalytic converter that needs to be replaced. Does anyone have any suggestions on remanufactured vs. aftermarket parts. I have been searching for remanufactured and can't seem to find a company doing this. Any help would be appreciated.

Cheaper ones are here.
Bavauto has a more expen$ive one. you need to go to their site and put your car in - it won't bring the link.

P.S.: I found another source here.
