which exhaust manifold to get ?

[Been]

Guys,

I need an exhaust manifold for my S4 (AAN).
Been looking at a few and this is what I found so far on the net:

I need one with T3 flange for my GT35R 1.06 and Tial wastegate (38+ mm).
Target: maxing the GT35R.

So which exhaust manifold are the high hp-number setups using ? and why ?....any advise on which one to buy ?

thx !

Here is also a option. Price is without the wastegate flange. You can propably get it with a Tial flange welded on...

You couldn't use the RS2 evo in the 2nd link without modification, the compressor housing is too big on the GT35r and hits the manifold.

You would need to use a spacer such as a t3 flange with two gaskets to space it far enough away to fit but then the hotside being 1.06 would hit the chassis

All in all use the Wagner SQ manifold if you are going for a cast version.
