Hello, good day! I have a problem and I can’t find a solution for that, and I’ve been in possession of a K5 Yoshimura Edition since the latest edition that has just down 11500 km. Now I’ve read in many articles that there is a cat in the K5/K6 I always thought there is a pipe going through from front to back. Now my question is, where should it be installed because I also have the special edition Yoshimura Trioval on it. The best would be picture so I know exactly what I’m looking for n has to write all toasters as well but I don’t even have such a thing because I was not aware until today that she has a cat at all. A second question still asks me how or what can you do to make the pretty one still a bit bangs that would interest me burningly. So I’m looking forward to the answer thank you already in advance MFG Phillip
