    Muffler behind Y pipe?

    i have seen a few cars on this site where the muffler is dumped right behind the y-pipe...does anybody know how this setup sounds or if it has any benefits over running traditional exhaust?

    benefits include not being able to pass traditional inspection, having high decibal cabin noise at all times, and +2 horsepower.

    pm blue28 he has that setup.
    Yah it can be louder but if you want quiet get a prius-justin
    Saves some weight, round mufflers aren't chambered like catbacks and no restriction going over the axle, sounds petty mean w/ a cam-like a cutout just slightly quieter.
    Worlds better no, but certainly a style to consider
