I think this was covered here before, that the 04+ WRX's shared the same exhaust as the STi's sans the pretty tip...
Actually that's not quite correct;

The first pic shows an 06 WRX axleback, as you can see, the STi piping (the cut flange section) is bigger. How much bigger? The WRX is around 2.16" (55mm), the STi is around 2.3" (60mm). The tips are also different, with the STi having slightly bigger inner diameter. Finally, I think the STi has less baffles than the WRX, it's a louder, lower, and more raw (more metallic) sound than the WRX. I ran both of these mufflers on a 2.5" exhaust without any resonator.
What does that mean to you guys thinking about using these mufflers? Basically, what exhaust piping and possible expectations you should see with either one. The WRX is better suited to be mated to a 2.25" pipe, and will probably sound more civilized on an NA subaru (keep in mind turbos are like mufflers in terms of quelling exhaust noise). The STi muffler would be better mated to a 2.5" pipe, or if you desire a louder more aggressive exhaust tone; it will also be louder than on any turbo Subaru that has this same muffler (keep note of this when you listen to exhausts). The STi muffler will need a bigger resonator than the WRX muffler to keep the rasp/raw sound down.
Either one is a great value IMO.
Exhaust clips to follow.
