If your catalytic converter has failed, you will need to replace it to pass inspection. We offer both Genuine BMW and money-saving aftermarket catalytic converters. If you would like to keep your BMW exactly the way it came from the factory, get this catalytic converter. It is a Genuine BMW catalytic converter, identical to the one a BMW dealer would install.
We highly recommend also getting our catalytic converter installation kit. It contains everything you need to properly install the catalytic converter, saving you both time and money.
NOTE: If your BMW is running properly, a catalytic converter should last the life of the vehicle. So why did it fail? Failure can be the result of a variety of issues, including damage, yet one of the most common issues is "improper fuel trim." If your BMW does not have proper fuel trim, and you do nothing about it, replacing the catalytic converter will not fix this issue and you may need to replace the catalytic converter again. For more on proper fuel trim and catalytic converters, read the article at blog.BavAuto.com/go/cat.
