I added the Corsa Cat back to my Hurricane SO in Gunmetal grey (black was not available yet).  Its definitely not the same sounds as my Borla S type on my Durango 5.7 Hemi...  But I never expected it to be.  Its really loud, almost obnoxious on start up, then quiets down after it warms up.  It's not perfect, but I like it better than the stock exhaust that was sooo whisper quiet.  It does sound a lot like all the smaller cars from the Fast n the Furious movies... but again, I like it and that's what matters.
