When are exhaust upgrades NEEDED?

Everyone seems to "upgrade" their exhaust no matter what. A majority of the time just for a better tone, growl, rumble, or whatever.
Ive got AA stage 1 with headers, rest of the exhaust system is stock. Im going to be upgrading to stage 2 this summer and was wondering if any actual power gains from exhaust work would help? the stock exhaust looks pretty big and appears to flow well, but looks and be deceving. I really like the sound I have now, just supercharger wooshing!!
