Default Size of STi axleback inlet?

Is it 2.25 or 2.5? I have searched a lot and have found mixed responses. Please don't tell me to go out and measure it, I won't see my car for a few days.

The reason I ask is because my wrx has an Invidia v2 catless DP, stock wrx midpipe with a resonater, and a 2004 STi axleback exhaust. I want a non-resonated midpipe just to have a throatier, maybe louder sound.

The invidia DP is a 3 inch outlet (right?) so I will need a midpipe that goes from 3 inches to 2.25 or 2.5 inches I am guessing. Any info would be appreciated.
