Just got the Ocelot exhaust. It came with hangers - but, I have no idea where they're supposed to bolt. The holes are quite large, and the old brackets had very small bolts holding them onto the frame.
Additionally, the old muffler had brackets holding it to the frame with springs - no brackets on the new muffler.

Might be some useful info in This thread.

I installed a factory ('85-'88 GT) dual-exhaust in my '84. Although the following shot is of my '86 GT, this is also how and where I mounted the rear hangers on both sides of the '84. What you're looking at here is the driver's side rear wheel well with the plastic liner removed. That's the inside on the rear bumper on the right. I drilled a hole in the frame on each side of the car to mount the hangers, and they're clamped to the exhaust tips just where they split into two. I like installing this type of hanger in this location as it gives me the ability to adjust the height of each exhaust tip in relation to the cut-outs in the bumper. The mounting is very secure and the spring suspension on each side of the muffler is not missed. When the wheel well liners are replaced, the hangers are no longer even noticeable.

Yep, no more springs. You need to use the hangers instead.

Patrick seems to have drilled holes for these to bolt into. Urf. I thought these were supposed to just bolt on.
My brackets look similar, yet different on the end. The one pictured is curved. The ones I have have a flat hook.------------------

"Urf"? Is drilling one hole on each side an issue? 
There might be existing holes that would be sufficient for the hangers, but I wanted precise tailpipe positioning (up/down & left/right) on both sides.[This message has been edited by Patrick (edited 05-22-2023).]

Because I wasn't expecting to drill any holes. I thought it was just bolt on. And my game in this particular area is...shakey.

I didn't drill any holes to install mine. I used the holes that where there from the stock hangers. I did however purchase the Rodney Dickman stainless steel hangars. Depending on the year of your Fiero will determine what hangars you need. Exhaust Hangers

Same when you installed my Ocelot exhaust system.

I'm trying to use the hangers that came with it. When I was at the Fiero Store talking to the fine folk there, they showed me a another set of hangers ( https://www.fierostore.com/...0%20%20LH&d=388&p=1) for an additional fee - but stated that they weren't necessary, the included hangers would work.
In the interests of saving the $40 on their word that I wouldn't need them, I passed.
Since they said these would work (their actual words were) "you'll see how they install when you get under there" I'd prefer to use them.
Now that I'm on an actual computer monitor, I can see much more detail from Patrick's photo. There are holes where the wheel well liner bolt in that might be used for that purpose - closer to the junction of the tailpipe and muffler.
But these hangers have a different end than the one Patrick has in his photo. Patrick's are curved and can clearly work with the design of the clamp. The ones that were included are flat. I'm concerned that if I tighten them down, that flat spot won't exert the clamping force needed, or worse, will break the pipe over time.

Those holes in the cradle are probably where the factory exhaust hangers attached. I used much stronger hangers and located them elsewhere as I wanted more control over where the tailpipes were positioned within the exhaust cutouts in the rear bumper cover.
