Lol ahh. It's either that or 2.25 heh wish I knew for sure cause I'm trying to order my E-cutout and I need the exact Dia. For fitment. I don't know if I could get away with it fitting right if I went with one that was 2.5 when in fact its 2.25? Lol

No worries..

So I went out and looked around on the side of the house. Didnt see it laying around out there....

I was able to search and come up with
GrimmSpeed 3in Downpipe to Stock Cat-Back Adapter Subaru Turbo Models at RallySportDirect.com

This says the piping is 2.25 on the rear exhaust.
(All Years) Exhaust FAQ - Subaru Forester Owners Forum

Thats about all I could find off the top of my head. I even looked in a few books I had. Found the oem up pipe size 1.67, But no down pipe.

Sorry wasnt able to help.

I'm pretty sure the 05 WRX had a 2.5in downpipe and midpipe with a 2.25in axleback. Might be wrong though. I'm installing my stock turboback tonight, so I can check for sure.

Measured it earlier tonight and it was in fact 2.25in where the downpipe meets the midpipe. Hope this helps!
