Just read another post on another thread. A guy has wired open the by-pass valve on his Tubi equiped and hiper flow (?) pipes. My question is how would it sound and has anyone done it on here? I ask becourse i have the de-cat Capristo set up and it seems that the Caprsto is finely tuned to have two sound levels and tones. The first levelbeing a low down rumbel and the second stage when the valve opens a higher and differant pitch sound which does not resemble the first level what so ever . I cant see how wiring will make the Capristo/Tubi sound any better becourse of the above, on a standard system yes i can see the reason. I am looking at the Capristo/Tubi as a very expensive musical instument and thinking will this be a waisted exorcise, what say you dudes?
