Is it safe to drive a car that needs a catalytic converter
Not really understanding the question.
Are you asking is it safe to drive a car WITHOUT one that is suppose to have one??
The car won’t blow up of that’s what you mean…however it probably won’t run right…since the O2 sensors send readings back to the computer that tells it how its running. Not to mention the added pollution you’ll be putting into the air.
Agree with Mike, in addition you are breaking federal and state laws by operating such a vehicle.
