Anyone else experience this code? My o2 sensors are functional( checked with scan tool). I think my cats finally gave up due to being caked with a thin layer of mud the past 30,xxx some miles. This happened on an extremely hot day after extended driving.

Unfortunately, those serious into performance know all about the p0430 & p0420 codes. A hi-flow exhaust system can produce those codes. Assuming you dont have too many mods and your O2 sensors are good, & the connections are good, then the next guess would be that yes, maybe your cats have failed.
