At Cal Smog Network stations:
Only if the part carries a CARB Executive Order (EO) number for your specific vehicle — the EO number is what makes it smog-legal when your car is tested at a smog station.
- A CARB EO number is required for the part to be street-legal
- We verify the EO number matches your vehicle before installing any aftermarket exhaust part
- Parts without a matching EO number are a common reason vehicles fail at the smog test station
Per CARB Executive Order database.
