Euro 5 homologated. Stainless steel system in a Black ceramic coated finish, with the muffler proudly sporting the laser cut VP logo. The headers are 45mm diameter and the muffler is 101mm diameter. Much shorter, sleeker, leaner and lighter than the stock 2-2 exhaust system. Easy bolt-on installation. 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 muffler comes in Black, a 900°C heat resistant satin black ceramic coating for lasting beauty. The end cap is CNC machined Ergal (aluminum 7075) in the Revolver design with a contrast machined 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 708848 for the Standard Db killer, see 708858 for the Racing Db killer.
