California-Legal Catalytic Converters
In California a replacement catalytic converter has to be CARB-approved for your specific vehicle — a federal part won’t pass. We install compliant converters and the oxygen sensors that go with them, so the check engine light stays off and the car passes inspection.
Fix the Section, Not the System
Most exhaust leaks are one failed part — a cracked flex pipe, a rusted muffler, a blown gasket. We put the car on the lift, find the leak and quote the section that needs it, not the whole system.

Exhaust Questions
Why is my exhaust suddenly loud?
Usually a rusted or cracked muffler, a broken flex pipe, a failed gasket or a loose hanger. We put the car on the lift, find the leak and quote the fix — often it’s a section, not the whole system.
Can an exhaust problem turn on my check engine light?
Yes. An exhaust leak ahead of the oxygen sensor, a failing sensor or a worn catalytic converter will all set codes. We diagnose which it is before replacing anything.
Do you install California-legal catalytic converters?
Yes. In California a replacement converter has to be CARB-approved for your specific vehicle, not just a federal part. We install compliant converters so the car passes inspection.
I smell exhaust inside the car — is that serious?
Yes. Exhaust fumes contain carbon monoxide. Crack the windows, limit driving and have the leak found right away.
