Catalytic converter and test pipes policy
In this article
In this article

Policy overview

eBay allows the sale of catalytic converters except for those that are prohibited by the U.S. government. We don't allow items that are designed to defeat, bypass, or shut down catalytic converters, oxygen sensors, and malfunction indicator lights.

Test pipes are allowed if they are marketed as race car accessories and are listed in the Auto Racing Parts category. Test pipes are not approved for use on street-legal vehicles.

Make sure your listing follows these guidelines. If it doesn't, it may be removed, and you may be subject to a range of other actions, including limits of your buying and selling privileges and suspension of your account.
