From the various sound clips I've seen. The STi has more bass and growl, while the Authorise S is more plain in its tone.
Some more thoughts on how those two compare.
The Authorize S sounds like the stock muffler uncorked - a little bit louder and clearer tone but still very much the same plain character of the stock exhaust.
The STi muffler has a more distinct character to it. More refined, very deep tone, not raspy or tinny.
