Difference between STi and WRX inlet manifold is only color,nothing more...
On some STi inlet manifold are removed TGV,which can increase power(some said 10-15%),but without the remap you will get CEL(Check engine light),due missing TGV.
I would suggest remove TGV on your WRX manifold,fit other parts like bigger turbo(VF30 or VF35),STi pink injectors,STi TMIC or FMIC,Walbro 255lph pump,3port boost solenoid and remap and you should have 330-350bhp

There is nothing to be gained from changing yours.
If you haven't done it already, a de cat and Ecutek remap will add an easy 40 bhp over standard.

Depending on the year , the later manifolds are better for top mount intercooler upgrades ? I think I am right in saying that , was a qestion i was going to ask ?

The only thing I can think is that the Spec C had a one-piece manifold with an extra sensor hole for a charge temp sensor........apart from that I'm struggling LOL
