210 Converter Replacement
 

Where can I find a 49-state catalytic converter for a 99 E430? I've seen prices recently and that is CRAZY! Does anyone make cheap knock-offs?

Double check by putting your car in the page and it should confirm it is the right one. Not for California.

There are two catalytic converters on each side. Do you know which of the four you need? The front ones are smaller than the rear ones, I think.

The OE ones include the pipe, O2 sensor bosses and two converters. Here in Canada, price was just over C$600 for the part. About 1hr labour I think.

You can also get aftermarket pipes with converters. This link has almost all of them:
