FAQ – Catalytic Converter Replacement
Q1: How can I tell if my catalytic converter is failing?
A: Common signs include a check engine light, poor acceleration, decreased fuel efficiency, or a rotten egg smell from your exhaust. If you notice any of these symptoms, it’s best to get it inspected right away.
Q2: Can you install a catalytic converter I already purchased?
A: In most cases, yes—but we need to ensure it meets California CARB standards. If it doesn’t, we’ll recommend a compliant option to ensure your vehicle passes smog inspections and remains road legal in California.
