GI: EVO Tubular Manifold

question... what does a 4-1 pyramid collector look like... i hate how all the pictures of ANY ****in' mani are all of the curly qs, **** the runners... i wanna see the collector.
Mental, I am pretty familar with exhaust pulse threory and improved flow from a good designed collector.
I watched the video. Your Manifold was a definite improvement on the stock Mazda log.
From my limited experience and listening to other tuners speak, (Buschur for one), I believe the stock Evo manifold is pretty good.
I even made mine better by cleaning up the casting flash, slight porting/polishing, gasket matching the turbo side and opening up the head side to the same as the exhaust ports, (don't use manifold gasket to match. It's too big).
I don't think you will get such a big gain from the Evo as you did from the Mazda, but I may be wrong.
That's my point. If someone shows me a before/after dyno with an improvement like your Mazda, I could see spending the $.
Got a dyno run in the future?

They make spending $900 seem cheap ($1199). Although it is for aftermarket turbo.
They also have a complete turbo kit in the works for around $4800.

The EVO VIII direct bolt-in manifold will be 304 stainless steel that is ceramic coated.
The 4-1 pyramid collector is to help exhaust pulse velocity and eliminate turbulance.
We will be posting pictures and dyno results in the coming weeks here:
