Catalytic converter theft is a fast-growing problem, with thieves able to remove the part in under a minute. One approach to deter them is welding steel plates directly over the converter, making it much harder to cut or unbolt. While this heavy-duty method can slow down criminals, it comes with a high cost and potential safety concerns. Any modification to the vehicle’s structure may affect heat dissipation, accessibility for repairs, and even compliance with safety regulations. Before choosing this solution, consult a professional mechanic and consider safer anti-theft options that don’t involve major structural changes.
