No not all chambers sound the same.  I'm gonna do something different next yr I just don't know what.  Custom Kooks TD's.  Go on LS1tech and do a search.  PIMP.  Isn't cheap but 3" from the collectors back.  That or my original plan Kooks stepped 1 7/8 to 2" w/ a 4" outlet into a 4" mufflex single hideaway tip and ditch the CME tip.  
So many options.
