Euro 5 homologated. Direct slip-on replacement for the stock mufflers. The ''Tracker Series'' design is influenced by race experience. The stainless steel mufflers are 80mm in diameter and each holds a catalytic converter. Like with all V Performance mufflers; the exhaust tone is nice and deep by using a special inner muffler cartridge design. The dB killer is removable. Finish is ''Black''; a 900°C heat resistant satin black ceramic coating. The end caps are carbon fiber. 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 708851 for the Standard Db killer. A Racing Db killer is not available
