    Without a cam change header performance increase will be minimal

    Ive seen almost 200 rpm without swapping cams This is a one off, Ive contemplated doing 5-10 of them if there was enough interest? They would be about $1850 and would bolt up to everyone's stock exhaust. It will not crack, its not made of thin wall like the other headers out there. Like I said, I'm seeing almost 200 rpm increase. The primaries are 2" od and the jacket is 2.5 that go into a 3" collector.

    Very nice drop in with good results. Might work on a race header as well which would require new mid pipe and waterbox. Extremely high quality part.

    That looks like a manifold.
    Here's what I built last year. Wasn't jacketed, and the coating, wrap, and heat sheilding couldn't cut the radiant heat enough... smaaall fire.
    The change in power delivery was insane. More everywhere and very responsive.
    The one I'm working on now is jacketed.

    That was kind of the idea, open it up and make it flow without making a mess of the engine compartment. We wanted it somewhat compact but with the performance. I also wanted something that was easy to take on and off without having to pull the head on/off with the header.

    We are working on a race header with Titan but it also will not be individual tubes, well ones that you can see . Most of the guys that build a header like that end up hanging a turbo off of it and the tubes end up cracking.

    How big are the primaries on your header?

    The one in the picture has 1.875, the jacketed is 1.625. It should be finished this winter.
    It is easier to bolt up than the stock manifold. There was only one bolt on cylinder 1 that was difficult to tighten.
    You're right, the weight of a turbo would be a problem without additional support.
