Default Borla Exhaust

I've always thought 2.25" piping was what I need for my N/A 2.5 RS but now there's a 2" Borla system up for sale that I'm looking into...

My questions...

What are the power gains of this? Anyone know of any evidence that I would need to know? How would 2" compare to 2.25"?

Anything else is also appreciated...

Exhaust flow is greater with the 2.25" allowing the engine to breathe better and produce more horsepower. I imagine the 2" piping would help maintain backpressure better and prevent excessive low end loss.

From a personal opinion, I felt no low end loss stepping up to 2.25" piping.
