I would expect a new oem cat would return better results than one that has literally fallen apart. HOWEVER replacing a cat without resolving the cause for failure is an expensive road to go down.
I think I would want to drive the car with a scan tool and atleast monitor what the O2, and fuel trims are doing before getting serious about a cat.
I saw that the t-stat was replaced 16k ago, but didn't see what temperature it's running for you. (I've replaced the Stat in my Saturn twice, first replacement was down into the 170s after just a couple thousand miles, second one has been in there for probably 70k now)
