Replacing a catalytic converter can be a costly affair, but it is worth the investment. Catalytic converters play a critical role in reducing the amount of harmful emissions released by your vehicle into the environment. In fact, it is a legal requirement for all cars, buses, and trucks to have a catalytic converter installed. Failure to comply with this law can lead to hefty fines, with some states imposing penalties of up to $10,000. So, if your catalytic converter needs replacement, it is important to do so promptly to ensure that your vehicle is operating efficiently and within the law.
