Default WRC exhaust manifold?

Guys,

Has anyone seen photos of the WRC exhaust manifold? I have yet to see a photo sans body armour.

So obviously it uses a WRX crossmember (versus an RS one). Now it has a boxer sound so I assume that it's still unequal length, and I'm assuming it uses a 4->2->1 design still.

So is it just a stock manifold that has been stripped of heat shields and ported a bit?

the JDM manifolds have a littel bit larger Inside Diameter then the USDM manifolds... maybe polished or honed and slighly port matched with the heads.

well judging by the way they sound and move i am going for a 4-2-1 equal length, but he longer tubes being on the cylinders who's exhaust port makes a sharp turn....obviously made of some pretty thick and tolerant materials so i am going to go with some kind of stainless steel with a ceramic coating, but it's not welded it'd have to use spring style expansion joints to handle the pressure created in there. i wonder how close i really am. i know the exhaust is fully ceramic coated as well as the turbo housing has to be to withstand the beating.

i'd be suprised if it did use the stock manifold. according to jan shim, both the stock manifold and the jun headers broke when used with anti-lag.

I've seen the WRC exhaust manifold in Tokyo Auto Salon earlier this year.
It looks like 4-1 to me. But they probably have various manifold for different stages.
I heard it is made by Maxim but I'm not sure how reliable this info is.
