I looked it up, best I can say is that it 'might' fit but it would be tight. according to this http://www.jegs.com/i/Flowm...0462/10002/-1?CT=999 the body itself is 13 inches long. Stock muffler on my 88 duke had a body that was 12 inches long, 12 inches high and around 4 1/2 inches 'deep'. I found a magnaflow one that was 11 inches long and had to rework the pipes to make it fit because it was not as tall. Info here: https://www.fiero.nl/forum/Forum2/HTML/103848.html
You might be able to judge how well or not this flowmaster one would fit from that. An extra inch in body length does not seem like much but don't forget that you have to bring in the exhaust pipe from the manifold to the lower input and certainly on the muffler I used that was right on the end of the final bend.
If you are set on a Flowmaster (obnoxious loud and raspy) you need the one that fits the 80's Camero. 2.5 in and out with the inlet offset. Had one on my 3.4 DOHC and to replace it with a Dynoflow to quite the car down. I think Flowmaster mufflers are designed for long run exhaust systems not the short run systems that Fiero's have.
