Not worth it on a modern car like your SS. If you check out the exhaust mods available they all include the cat(s) You may find performance versions of them but since they are a part of the emmisions control on the vehicle they should stay. You may actually find gutting them kills performance unless you have the means to adjust the computer so it knows they are not there. I also don't think gutting them will have much impact on how loud the exhaust will be. The cars mufflers are what really determin how loud the exhaust is..
