For Euro 4 systems the baffle is replaced and a catalytic converter is added too. The cartridge baffles and catalytic converters are welded in place and are non-removable - For what bikes is the approval valid? The EC / ABE certification is valid for unmodified stock bikes, for the specific models and model years as mentioned in the product descriptions - Registering your Thorcat? Every Thorcat exhaust, and the individual components used for approval, come with a unique serial number.

Once registered, you will receive a Thorcat ID card that can be used to prove the legality of your exhaust system
