your 25-550 will make "550" HP (not whp) max under ideal circumstances. To make more you'll need nitrous or a larger turbo. There are direct fit options such as the 25-660 and 30-770
The OEM manifold has seen over 400whp, the Peron tubular will easily support 200whp over the OEM manifold
Your flow restrictions at that power level will be cylinder head related (port size, valve size, cams) not the tubular manifold
