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 8V S3 sedan (2.0T, quattro) category. Confirm engine, drivetrain and model year on the retailer page before ordering.
