  • Downpipe question

    Hi chaps, will be making myself a 3" downpipe shortly, waiting for my flanges to arrive, what size pipe/bend do I need for the wastegate outlet? I've got plenty of 2" stuff and bends but is that overkill?
    Cheers.

    just make sure that the size of the wastegate pipe is the same or bigger then the waste gate outlet
    i've use a tial 44mm and my wastegate pipe is 45mm big
    I guess it can not hurt to use 2' but you get no advantage from it
