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...
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.
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.

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.
