Recently the rear part of the rear silencer was separated from the pipe … Got a new one now. … But a positive thing had that when it was broken: the sound!!!

How does it look at the ASU afterwards .. or does someone recommend something else to me? I also heard that the hole helps to run the condensation water to Greetings Fiestadrive
