What Flowmaster muffler will fit 92 explorer sport?

I want to get a flowmaster muffler for my 92 Ford Explorer Sport 4.0 v6. I would like a super 44 but on every website it says it won't fit on the explorer. However, I see many videos of the 92 explorer with many different Flowmasters including the super 44's. Would I have to change the whole exhaust or would the 44's fit the stock exhaust?
