At some point I will be doing a turbo back exhaust system. I want the best flowing set-up I can get, but I don't want loud at all. Ok I don't mind a bit deeper tone, but nothing loud, fart can loud or otherwise noisy.
What muffler set up should I use, OR can I use the stock set up with a good down pipe?
The stock muffler isn't very restrictive, it's all the junk in the cats leading up to the muffler that are restrictive. You could run a new down pipe and mid pipe, and use the stock axle-back with no problem.
This is your quietest option. If you're looking for quiet and want to keep the stock look and stockish volume, just run a downpipe. It's also what they call a "stealthback" exhaust.

TurboXS "stealthback", Borla Hush, Fujitsubo Legalis-R, maybe SPT, Maddad Whisper, Tanabe touring Medallion.
...maybe Cobb, but then your getting into the next step up in loudness.
