Smog & Emissions
CARB Compliant Catalytic Converters
Only EO-numbered, California-legal converters get installed here.
California requires aftermarket converters to carry a CARB Executive Order number stamped on the shell. Anything else — including most units sold online as 'direct fit' — fails the visual smog inspection on sight.
We source the correct EO-numbered converter for your exact year, make, model and engine, install it, and verify catalyst efficiency before you leave.

Questions
Straight answers
How do I know a converter is CARB legal?
It has an Executive Order (EO) number stamped into the shell. We document it on your invoice.
Is a factory converter required?
No — a CARB-compliant aftermarket unit is legal and costs less than OEM.
Will it pass smog?
With the correct EO part and the underlying fault repaired, yes.
