Your car’s catalytic converter is one of many essential components of your vehicle. It’s important to your vehicle’s exhaust system as it filters and burns up harmful byproducts. Put simply, it converts these byproducts into steam. Unfortunately, they are commonly stolen because they are very valuable. If your car is louder than normal, it may be missing. While it’s possible to drive without, it’s illegal to do so. It will also reduce your car’s overall performance.
