I have a Turbo XS
TBE fitted to my 08 WRX, cost me about $1200 however I did go for the option of an ECUtek tune (which was the only thing available when I tuned my car) and this cost me $2000.
The exhaust is great, nice note without being too loud. Check out there website

They seem to have 09 sedan systems on there and a few videos and audio of the sound
