I just got off the phone with AA, and they told me they're STILL waiting for a 230i local to the South Florida area so they can finish the testing and development. Hell, I'd drive down to Miami myself but I'm in PA! Maybe if no one has gone by March I'll go.
That being said, if anyone knows of any 230i owner in the South Florida area, please get in contact with AA! Their contact info can be found here https://store.activeautowerke.com/pages/contact . They said they'll put on the exhaust and everything for no charge, just pay the 228 exhaust price.
