Can a 2012 Buick Enclave run with a punched out converter?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! I know cat codes are frustrating but why do you want to punch it? Yes, your vehicle can technically run with a punched-out catalytic converter, but it’s not recommended. A missing or non-functional converter can cause poor engine performance, increased emissions, and a check engine light. You might experience a loss of power, engine misfires, or unusual exhaust noise. It’s also illegal in many areas and can lead to fines or failed emissions tests. For the sake of your vehicle’s health and staying on the right side of the law, it’s best to have a proper, functioning converter in place. If you've been having issues for a few weeks, addressing it sooner will prevent further complications. If you have any other questions, please call us at 877-913-1554!
