    Single exhaust manifold or twin scroll ?

    For my new turbo setup I need a new exhaust manifold.

    The turbo is a PT7675 CEA this turbo is not a twin scroll.

    What is the better type of exhaust manifold for a no twin scroll turbo ?

    Thanks

    I would think there would be no benefit whatsoever of choosing a twin scroll mani unless you were just planning to go twin scroll turbo in the future.

    After you get information the conclusion is that for the best performance I need a twin scroll manifold with twin scroll turbo or a "single" manifold with a single turbo, so for me is single with single

    The mixture of the two is really not ideal, but it works well on.

    With 7675 if have come out in 1000 (w)hp in my opinion I'd be happy for a long time and therefore not want to change.

    Home to U.S. cars in 1000 (w)hp is common but in Europe (except Suede them are crazy LOL) is very rare and my KNOWLEDGE in France nobody have a BMW with 1000 (w)hp

    NOTE:
    I don't work of the car this is my new tuner/friend that does the job.
    I'm doing in "theory" but in practice (mechanical) I'm bad.
    I prefer to always leave the work proffessional or friends who really know how to do a good job.
    Just a example of work:

    Is a downpipe for a VW Golf II VR6 turbo (GT35)

    I hear you in Europe it's pretty much the Swedes but there must be some tuner who can help you.
