Welcome to the fold.
I was about 5 minutes away from hitting the purchase button on the Nameless "w/muffler" axle-backs for the 08+ WRX/STi sedan, but my buddy got back to me with decent pricing on the Perrin's, so I went that route.
From looking at the hangers, I don't see why they wouldn't fit. You could probably find a set used on NASIOC as well.
Do it up!
