Can't lose with GMMG, Borla, or true duals IMO.
Flowmaster also makes an awesome albeit cliche sounding muffler.

Forgot to mention the 2OTL.. 2OTL and Hooker are the two best cheap catbacks you can get. I will most likely run a 2OTL on my next F-Body if it's a Camaro.
I was never a big fan of Corsa. The make quality is good but the sound is horrible IMO.
