Default Low dollar 1980 exhaust solution

I found a thread that said that one of the 80’s biggest weaknesses is the cat and the headers. I was thinking about removing the cat, would there be any down side to this? I live in Utah and won’t be dealing with emissions. I was also thinking about changing out the headers. Are there any good manifolds that aren’t restrictive that I could scavenge or are new ones my best bet?

An all stock 1980 is not that restricted by the single Cat . But that was 40 years ago who knows what shape it is in now. When performance modifications start to happen with the Engine then it also becomes a restriction. There are no other Exhaust Manifolds that are going to make a bid enough difference to be worth the trouble of changing them. The next step would be to go to long tube Headers and a duel Exhaust. To do this on a 1980 You need to change to an aftermarket Crossmember.

Low dollar exhaust solution, right away I was thinking soup can wrapped around the hole with a couple worm clamps holding it.
I was young once.
As per Your Cat delete question. Look on Ebay for a "Test pipe". Basically replaces Cat with a section of pipe.
didn't think 80's came with any kind of headers. Thought they just had 2 inch manifolds like earlier cars. Guess I don't know much about 80 models.

I’m new to exhaust, I’m not quite sure the difference of manifolds and headers.

one is made of pipes and the other is thick cast iron.. The cast iron manifolds typically flow less.
