From what I've read here's what I know. The AA has a higher pitched tone while the Gintani is deeper sounding. Gintani's system is a bit lighter. I think the Gintani is louder as well.
This is pretty much bang on. I have an AA exhaust and someone I know has the Gintani and I have heard them side by side.
Good luck with the sale - the Gintani is a very nice exhaust. Love the sound.
