Euro 3/4/5 homologated. 100mm diameter. Chrome plated stainless slip-on mufflers. 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 mufflers proudly sport the laser cut VP logo. The end cap is CNC machined Ergal (aluminum 7075) in the Banger design. 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 708848 for the Standard Db killer, see 708858 for the Racing Db killer. Note: Mufflers can be installed with the stock ECU
