Gents, is there a way to clean or at least check the cats to see if they are healthy? I replaced my header for euro headers and after moving my post O2 sensors I get a low voltage heater in the bank one sensor 2. I already replaced all the gaskets and one O2 sensor and the CEL comes back after clearing it error.


Any thoughts?
