Optimum exhaust manifold?

Heyas.

Been collecting parts for a turbo setup for my Aus A body and have decided a set of magnum manifolds would be best.

These are quite rare in Australia (none sold down here).

Clearance on components shouldnt be an issue I imagine as they will need to be swapped left/right, ending up facing forward.

I have narrowed my choices down to the 92-93 dodge/jeep manifolds with the 2.125" exits. Would these manifolds flow about the same overall? Are the jeep units the same on the exits? I have read a few posts that indicate they are anywhere from 2.5-2.25", but I have no way to check for sure.

Thanks in advance.

I used the Hedman Block Huggers. If you go this route 1st thing you need to do is Throw the Reducers in the trash and make your own pipes. They choke the exhaust down at the collector to around 1.75" instead of being 2.5".

There are a TON of pictures in my build thread so you can get some ideas if you want.
