So my car’s check engine light came on two days ago. I brought it to auto zone and they diagnosed my car with the codes showing the catalytic converter is bad. I dont want to go through a mechanic for the part, because it will be an arm and a leg, so i would rather buy the part myself. Anyone on here bought a catalytic converter and had the mechanic install it? Also do i need one or two of them? I currentky own a 2011 LT camaro

found this online... will it fit under my car?

 

Visual inspection will dhow if you need two or not..
If you need one, you'll need the other side
OBD II should have told you which one.
