My 2005 Buick Century with 353k miles gets a recurring P0420 code, catalytic converter operating below efficiency level. Twice this year, I tried using Cataclean, but with no success. I noticed a small hole in my muffler at the seam. Could a lack of exhaust back pressure cause the CC to operate inefficiently or improperly? Can anyone recommend a catalytic converter cleaner? Or, is it all snake oil?
No, lack of backpressure has nothing to do with your issue. You need a new catalytic convertor most likely

My Pilot is lighting up a catalytic converter code on the dashboard. My Boch Honda dealer service is quoting $1,037 for the replacement part and more than $600 for the labor. Does that make any sense? The car has 180,000 miles on it. Should I just go with non-Honda parts?

I drive a 2004 Ford Ranger, which I’ve had for the life of the truck. For a few years, I’ve had the CEL on more often than not, usually for codes related to oxygen sensors and cat converter. I’ve taken the truck to a couple of shops and had O2 sensors replaced (repeatedly), but the CEL has come back on within a few days. I’m not at all experienced with auto-work, but I’ve been trying to pick up some new skills (in the interest of not going broke). So, aside from the shops doing their work, I’ve personally replaced a couple of O2 sensors, one catalytic converter, fuel filter, plugs, etc. Betwee
