when running a 3" v-band single turbo, when does it expand to a 4" exhaust if you wanted a 4" exhaust? whats the best (or only) place for the 3" piping to expand to 4" piping.

On the downpipe. That's assuming that your running a full 4in. exhaust.

thanks guys, just to let you know, the reason I'm asking this weird question is that I'm making a custom single turbo setup for my 3000GT and I needed to know where the best place would be to start the 4" piping to my exhaust if the turbo i'm using had a 3" v-band exhaust.

i assumed you guys on SF would know best :D
