Hello…….. I have a CBR 600 Bj. 2002 PC 35. Now I would like to get a sports exhaust for some time now, in order to spice up the whole sound. I’m not about performance but about a rich sound. I don’t want a complete system, but just a rear silencer. Can you tell me your experiences, which pot has a great sound. Akrapovic, Sebring or BOS, or another one. Would be really great. Or only the exchange from the end pot brings nothing. Because age is too expensive for me. Greetings
