Device for adapting noise reducer on exhaust silencer of e.g. motor bike, has ring system formed of set of rings, where each ring increases diameter of system by two mm until system reaches diameter required by reducer to fit with silencer

摘要

The device has a ring system formed of a set of rings (2) with different diameters (1). Each ring increases the diameter of the ring system by 2 mm until the ring system reaches a diameter required by a noise reducer (4) to fit with an exhaust silencer. Each ring includes three holes (3) for allowing passage of screws to fix an assembly, which is formed of the noise reducer and the device, inside the exhaust silencer.
