Charger SRT Hellcat
My wife was driving my car the other day (on the racetrack) and the check engine light came on so it’s her fault. The code is a P0420 which indicates catalytic converter malfunction. The car has had catless mid pipes with the Big Daddies 02 simulator extensions installed for almost two years now (off-road use only) it just decides to throw a code? I cleared the code and haven’t driven it since so not sure if it’ll come back on, but any suggestions? Possibly replace 02 sensors? Anyone running catless experience this after such an extended period of time with no codes?
