Euro 5 homologated. Ready to replace the stock 2-1 exhaust system, with its extremely oversized single muffler. This is a precision made stainless exhaust system, complete with catalyst converters, for a fully legal replacement that does not get you into trouble during a routine traffic stop. Fitment is a direct bolt-on replacement for the stock headers and mufflers. The system comes with a black, 900°C heat resistant satin black ceramic, coating for lasting beauty. Mufflers are 80mm diameter and end caps are CNC machined Ergal (aluminum 7075), in the 'Double Ring' design, also in a satin black ceramic coated finish. Note: Homologation is valid for unmodified stock bikes, for the specific models and model years as mentioned in the product description. Removing or modifying the standard Db killer will void the homologation. Note: See 708849 for the Standard Db killer, 708859 for the Racing Db killer
