"Pa-Ri" 48mm x 20mm wide stainless steel 48mm exhaust clamps, THE nicest I have ever seen. Some CONTI mufflers require a 48mm clamp. 45mm size fits ALL bevel drive twins head pipe to crossover, and most original Silentium and LaFranconi mufflers as well as the early CONTI mufflers. Make sure you measure your existing clamps to get what you specifically need for your bike. These can be polished up to a mirror finish in no time if desired. Very well made, finish is excellent.
