Running your car without a catalytic converter is better than running it with a fouled ( plugged ) one. It will cause your car to release more pollutants into the air and may be illegal where you live. It is best to remove your bad convertor and replace it with a new one.

It is illegal in all 50 states to remove a converter. Minimum fine is $2,500 if you get caught.
