not around here, you dont have to have a converter in your exhaust system. I think it should be required, I mean it doesnt cost a whole lot and it saves the earth too. Either itll stay in or itll get replaced by a high flow.

Your best bet would be to get a good high flow cat since your car has that many miles on it. The high flow cats will free up horsepower and fuel mileage that the stock cat restricted and it only takes about 1 horsepower away versus a straight pipe and keeps you legal too. You can get them for between $60 and $120, so it's not a wallet breaker like the stock replacement cat is.

Is there any way to test the cat at home? I mean, instead of "unwelding" it from the tubes to look through or anything, is there a flow test? I suppose I would get a CEL for low catalyst efficiency or something if it was bad though right? I think im just gonna leave it. The DOHC muffler will be improvement enough, but I dont know if I can justify 80$ purchase to POSSIBLY free up 1mpg

Generally when a cat is bad it will make the exhaust smell like rotten eggs. Another way to check it is a night, run it on the freeway and pull off to the side and look under the car at the cat, if it's glowing red then it's plugged which is why it's getting that hot. There is also an O2 sensor at the back end of the cat which lets the PCM and you know when it isn't functioning properly or if the catalyst is gone, but it won't show up if the cat is plugged. If you have 200K miles on it then you should replace it, because it is costing you in the long run by reducing your fuel economy which adds up quickly at these gas prices.
