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.
