The BOS Midget rear silencers have a nice, deep, rich sound. The DB-Eater is removable and all necessary mounting materials are included. An E-number is engraved on the silencer, which serves as proof of approval. Thanks to their high-quality workmanship, the BOS Midget (4-2) rear silencers are a real eye-catcher on the Suzuki GSX-R 1000.
