2" collector with 70mm exhaust?

I have 06+ Si and I'm looking to get a DC/Strup race header (no cat), which both have 2" collectors. I already have a skunk2 70mm exhaust. Not sure what size stock is.

How much would this be holding me back?

From what I've seen that motor likes at least a 2.5" if not 2.75" -3" collector on an aftermarket header so I'm pretty sure yhat DC header will hold you back a fair amount.
