4 Branch exhaust manifold, which one?

[juan]

Im wondering what are the pro's and cons of the four branch manifolds that are avalible?
and which would be best for me running an eaton conversion.
Performance is paramount as i dont want to go for the cheapo exhaust and save £90 if its going to choke the engine,
but i also dont want to go for the more expensive manifold if its just a case of it being pretty.

The ones i know of are:

Phil j supplied 4 branch.

ebay hottuning 4 branch

G-werks 4 branch

PPP 4 branch

i can narrow your choices down

hottuning and phil j one i think are both ta technix made. Both need a lambda probe boss welding in.  These have a 1.75" exit.

G-werks and PPP are both the same company that made them for Pitstopdevelopments.  These have a 63mm (2.5") exit

ahh that makes the choice pretty easy then, itll have to be a G-werks or ppp one then
