2.25" for the WRX exhaust piping, about 1.75" (I think) for the 2.5RS.

1.75"? I have some of my stock exhaust piping at home, I'll have to get out a ruler and check that...

Well, I upgraded my exhaust to 2.25" mandrel bent piping & it's much beefier than the stock stuff.

Just to add to the confusion, I believe it's 1-7/8" on a stock RS.
