Euro 3 homologated. This is a Cobra USA manufactured exhaust that is modified by Thorcat to EC regulations with an EC / ABE approved cartridge baffle. Catalytic converters are installed on Euro 3-4 models. This makes the Thorcat-Cobra a 100% legal exhaust system. The EC / ABE certification is valid for unmodified stock bikes, for the specific models and model years as mentioned in the product description. A classic Hot Rod 2 into 2 system with cutting edge features. Comes with full size 2-1/2" diameter, full length heat shields that wrap 222° around the exhaust pipe. Complete with chrome plated billet tips. A special 'power port' is used to connect both mufflers for increased midrange and bottom end torque. Note: Euro 3-4 certified exhaust comes with EC / ABE approved non-removable cartridge baffle and catalytic converters. Note: Every Thorcat exhaust, and the individual components used for approval, come with a unique serial number. You must provide the bike's VIN number (frame number) to register your exhaust system in the Thorcat register; a document on how to do this is included. Once registered, you will receive a Thorcat ID card that can be used to prove the legality of your exhaust system.
