The BOS Midget Slip-on rear silencer has a beautiful, deep and rich sound. The DB-Eater is removable and all mounting materials are included. The connecting pipe is attached directly to the original manifold and the silencer is held in place with springs. It has an E-number engraved on it, so you don't need to register the rear silencer in the vehicle documents. Thanks to its high-quality workmanship, the BOS Midget is a real eye-catcher on the Honda CBR 600 F.
