    Quietest Aftermarket Perf Exhaust

    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?

    I went with the Miltek Sport eventually and find at times it's quieter than stock. Sounds amazing! Pricey though

    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.

    You never mention what car, if it's a 08+ keep in mind ots map from Cobb specifies a full tbe so going stealth back might need a other map.

    Car in sig.

    Yes when I get the exhaust I will get an intake, and maybe other goodies including a tune.
