Before you install
In California, a new aftermarket catalytic converter may be installed only on a vehicle its EO lists, and only after the vehicle's emissions warranty has ended and the installer has documented a real need to replace the old converter. If your vehicle is still under its emissions warranty, ask the dealer first. Not legal advice.

Read the EO at CARB and compare the vehicles and conditions it lists with your vehicle. The details on this page were extracted automatically and haven't been reviewed one by one, and CARB's document is the one to go by.
