Euro 5 homologated. 90mm diameter. Chrome plated stainless slip-on steel mufflers, proudly sporting a laser cut VP logo. With catalytic converter and removable Db killer. Like with all V Performance mufflers, the exhaust tone is nice and deep by using a special inner muffler cartridge design. The end cap is CNC machined Ergal (aluminum 7075) in the Chubby design with a contrast cut black ceramic 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 708850 for the Standard Db killer, see 708859 for the optional Racing Db killer.
