Should I remove the cat? (1 Viewer)

[Gsw234]

I admittedly don’t know much about catalytic converters. I’m wondering if I would benefit from removing mine. Here’s the details.
1984 fj60 with desmogged 2f. Runs well. Has original cat. I’m not sure that it’s working or not. (I do know that at one point the whole thing was bright orange it was so hot. This was while I was working on the engine,figuring out all the gremlins.)
The muffler is a dynoflow that I added on because the original was rusted out.
Would I see power gains, fuel efficiency gains by removing the cat? Definitely is not required here in Montana. I don’t know if it’s helping or hurting or doing nothing at all. PFA. Thanks!

If it's the original brick, it's doing nothing by now, and perhaps is even clogged and causing excessive back pressure. I would remove it and replace with a cheap weld-in. Truck will run quieter and you won't get that exhaust stink. If you don't care about any of that, then by all means remove it.

X2 above. I had the original as well...lost it when I installed new exhaust. Its a bit cooler sounding, no performance gain, and smells......I will eventually install a new free flow style one like this..... or Flowmaster version

Thanks for the help guys. I guess there’s no benefit in keeping this. Maybe I’ll take it out and see if there are any big changes and then replace it with a new one if the smell is annoying.
