Looking for a better muffler...

I'm looking to upgrade from my stock muffler on my 93 GA. Any suggestions of a good one for these cars?

I didn't go the performance route but when the cat back rotted out on my 90', I went with a Walker cat back and for about 5 years now it looks like the day I installed it. Has a different note to it but not raspy by any means.

I had flowtech mufflers on my taurus and they held up pretty well and sounded pretty good
