Before you order
- Removing or replacing a catalytic converter with a part that is not certified for the vehicle is illegal for road use under the federal Clean Air Act. Catless parts are sold for off-road use only.
- In California and other CARB states a replacement converter needs an Executive Order number for the specific vehicle.
- Check the retailer listing for whether engine software changes are required.
- Listings are read from the retailer's F22 M240i coupe category. Convertible (F23) cars share mechanical parts. Confirm drivetrain and model year on the retailer page before ordering.
