What is the factory sizing on a 92 with the 5.0? Isn't it 2.5"? Mine was rotted and rusted through in some parts, and the piping was weak and you could bend it using your hands. So I took it in and asked their recommendation, they agreed with dual exhaust is not a good idea for these, but 2.75" was the best suit if I was wanting the best performance out of it because it's not too big but it opens it up a lot allowing it to breath better.
I've never been a big fan of flowmaster (they're not bad, but I've usually gone with magnaflow). Wanted to go that route again, but didn't plan on replacing the the entire exhaust, and the 40 series was a lot cheaper so I went with that.
