If this symptom occurs, you can use a vacuum gauge on the intake manifold or an exhaust back-pressure pressure gauge before and after the converter has been installed.
Can a car run without a catalytic converter?
Technically, yes. Older cars ran just fine before catalytic converters became commonplace in the 1970s. So, if your question is whether your car will run without one, then it most certainly will.
