Took my 2017 charger hellcat into the Dodge dealership for a recall on O2 sensor. So they replaced both cats and sensors got my car back and sounds like the exhaust is muffled and not running right took it back to them with the same check engine light on and they said the sound could be the new cats puts on! (Catalytic) Answers please!!!!!

Yea it was a code on the CEL P4030. But it’s something wrong it feel like it’s a lost in take off and everything else has to be something wrong! Wasn’t running like this when I took it into the dealership
Well the effects on horse power? From 60+ when I stomp it just run like it’s lost power.
What you mean when you say flash it?
