Gussie2000, on the other hand, has twin dynomax super turbos and they sound damn near stock on startup and idle and "normal" driving - but get on it a little bit and they growl like mad.
X2...
Been VERY happy with my choice of DynoMax Super Turbo (#17747 - 1 in/1 out)
Just as Ven described...almost as quiet as stock at idle & moderate acceleration, but barks pretty good when you put your foot in it...
