The Bos oval Screw/on rear silencer has a beautiful, deep and rich sound. The DB-eater is removable and all necessary mounting materials are included. Only the original gasket needs to be inserted into the BOS flange. An E-number is engraved on the silencer, which serves as proof of approval. Thanks to its high-quality workmanship, the Thorcat oval rear silencer is a real eye-catcher on the Suzuki RF 900.
