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.
