Because proper installation plays a major role in the catalytic converter's performance, the EPA has strict replacement requirements and regulations. Among these is the potential for up to a $25,000 fine for improper installation. Although there is no law that says you can’t install a replacement catalytic yourself, hiring a knowledgeable technician is the wise and cost-efficient choice if you are not a skilled DIY mechanic.
