Removing cat from muffler

If I remove the cat from my muffler or buy a aftermarket muffler will I need to do a tune?

No you don’t have to tune with just a aftermarket exhaust, but if u want performance gains out of that exhaust you will need to tune,

So is it worth the time removing that cat to lower the exhaust temps on a stock machine?

Michale is correct. You should see ~8-10*F lower coolant temps.
