I have the Flowmaster, which I purchased from West Coast Fieros. However, I hear that the Spintech is comparable. Check both manufacturers to see which one is a direct fit. At the time I purchased the FM, it was adapted for the Fiero by WCF. I've read some negative reviews of WCF, which is why I recommend you contact the manufacturers first. WCF does not have a very good reputation for delivery and consumer relations. bb
I have TFS Ocelot V6 exhaust on one of my 88GTs. No complaints on sound or price...very reasonable. The exhaust is louder, but not annoying.
Fitting the exhaust can be a little tricky as you new to move it around before tightening the middle section.
I painted the exhaust before-hand with VHT manifold paint. Make sure once you receive the exhaust that it is clean before painting it. Two cans should be enough. The exhaust needs to be room temperature, and dry in room temperature too for best results.
You'll need to weld on the muffler hangers on the new Ocelot exhaust from your original GM exhaust. The Ocelot doesn't have it.
Walker is not bad, and will have the closest sound to a stock fiero exhaust system.
I have no experience with the spin-tech exhaust that west coast fiero sells. The borla V6 exhaust was available 15 years ago as they made a special production run. It was made from stainless steel that would out last the car, like the Borla would say...
If it's sound you are looking consider removing the muffler and just keep your cat. It sounds the same as stock just throatier and a bit louder. I have this on my 87 gt v6
On my ls4 Fiero I have no cat or no muffler, it's LOUD though
I really liked the sound of my Walker stock replacement muffler assembly with a 17" glasspack installed in place of the cat. Very little to no drone with a very noticeable and pleasing exhaust tone. Fairly easy to install and very affordable too. Nice option to consider for a daily driver. Otherwise... Spintech all the way.

Currently has a Flowmaster, appears to be a stand 40, but not correct for the Fiero and only a single exhaust. Installed by PO with no cat and very "buzzy" I ordered a Spin Tech from WCF and got it quick enough. Appears to be well made and the mod looks good but won't be able to comment on the stock fit due to the exhaust relocation with the 3800 conversion. Having it installed this week so we'll see.
3800 sc3 using the spintech with flowmaster cat all the exhaust is run across the engine like the stock fiero setup and is nice and quiet so no cops think differently that I have an engine swap.
I have never replaced a Fiero muffler in my life. I guess it's an east coast rust thing? Personally, I would get a factory muffler at at local PNP rather than aftermarket. Muffler quality is going to be guaranteed with a factory muffler. Kit

That's exactly what I did when the factory muffler in my '86 GT started making an obnoxious "waap waap waap" noise at a certain idle RPM. Picked up a GT exhaust from the cat back at the wreckers for next to nothing. She now purrs again.
My 88 has the Ocelot exhaust, from the fierostore, with a free flowing Shuttleworth muffler. It sounds pretty darn good, has a nice burbling sound at idle, louder than stock, but not obnoxious.

I never bothered to worry about whether "Shuttleworth" was a brand name or a type/design. I just like the way they sound. Never have heard the stainless version, though. A bit rich for my blood.

My Fiero has the Ocelot cat-back exhaust for the V6. The exhaust sound is similar to a stock muffler, but more aggressive.
For a short time, I had a "bullet" style glass-pack muffler on the Fiero. I hated it. It sounded really nasty, and had this annoying "buzzy" noise above 3000 RPM.
No one's posted an audio clip or video of what their Fiero sounds like with the engine under load. IMO, that makes a huge difference with how the exhaust system actually sounds.
Not a GT, but this is my 5-spd Formula at autocross. Basically a stock 2.8 with 1.6 roller-tip rockers, ported exhaust manifolds, OEM cat, OEM muffler.
I don't have any recent recordings of the engine. But the exhaust hasn't changed much in several years...
Blacktree, I love the sound of the idle on your 3.4 engine.
Your second video seems a bit squished sideways. (Upon closer inspection, I guess they're both squished a bit.) If it's supposed to be presented in 16:9, go into Edit for your video on YouTube and paste the following into the Tags box. It'll be fixed right up.
