Default Help! What midpipe size?

So im getting a midpipe fitted to my Impreza 2.2L and don't know what size I should go with. 2" or 2.25"? I have Ganz intake, Borla headers and the pipe will be bolted to a OEM WRX axle-back. Any suggestions? What size will provide the best results? Thanks

IIRC, when i had my exhaust done, they told me the midpipe was 2". just go to an exhaust shop (it'll be the cheapest by far). They'll be able to tell.

go 2.25" That far back in the exhaust stream, 2.25" can't hurt performance in any way. And larger piping will help overall flow. The WRX exhaust is 2.25"...
