I just bought everything all this on HT and I have no need for this now. This guy had all of it on a turbo d16 but im sure it wont take much at all to make it fit a b series. Most of the piping is 2.5inch which includes some stock greddy piping which is 2.25 if I remember. The IC 20 inches long 7inches wide. It is pretty solid (heavy) and im unsure of the brand. It was painted black and the fins have a little nick here and there but nothing major at all. prices are below.
