Do you need a catalytic on a 1994 Subaru impreza?

Yes, a 1994 Subaru Impreza requires a catalytic converter as part of its emissions control system. The catalytic converter helps reduce harmful emissions by converting harmful gases into less harmful substances before they are released into the atmosphere. If the catalytic converter is removed or malfunctioning, it can lead to increased emissions and may cause the vehicle to fail emissions testing. Additionally, it is illegal in many places to operate a vehicle without a functioning catalytic converter.
