Anyone have experience w Magnaflow CARB Cats 444106?
Hello, Anyone have experience with MagnaFlow California Grade CARB Compliant Universal Catalytic Converter 444105 ? or any other CARB universal cats?
I've been doing quite a few things to clear codes P0422 P0432 on my 2006 CLS55. I even install the OEM tune to see if the code will stay gone. It seem Im on the path to getting new catalytic converters. Im in California so I need CARB cats. Also Muffler shop wont install used cats here. TIA.

Are your cats bad right now and is the reason you can not clear codes?

Most likely the cause are the cats. advised from my indy service whom i trust. also they are original 146k miles. It would be tough for me to sell the car as is in Cali.
