Euro 3/4/5 homologated. 100mm diameter. Black ceramic coated stainless steel slip-on 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 mufflers come Black; a 900°C heat resistant satin black ceramic coating for lasting beauty. 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
