De Cat

If you're leaving the airbox alone and the stock mufflers on. Yes. Probably even with a better set of slip ons too.
I gutted a cat yesterday and put it on with no effect to performance that I can feel. I do have a FP3 and cvo slip ons with 2" baffles. But I didn't flash a new map. Just gutted the cat.
I did notice. No more heat.

16" x 1" paddle bit and some patience. I tried the just drill straight through method. That sucks. Then I did the aggressive jam while spinning. That made quick work of it. I took a pry Bar and scraped the side to make sure it was all removed and that's it. Put it back on you're done.
Make sure you remove the o2 sensors.

Three ways
A. Take header off, long spade bit and drill it out. As best you can. Yuk!
B. Take header off. Cut a window in the side of header to expose catalyst. Remove cat material with a chisel and hammer. Then weld window back into header.
C. Look for a decatted headpipe on eBay for $125+/- and swap it out.
O.P. For what it's worth. Bike would probably be ok. Just runs so much better with a tuner. Night and day. Especially on those Rushmore bikes.

Personally there's no way I'd run the bike decatted without some form of tuner! I'd have mine dynoed but if nothing else get a tuner like a FP3 or a Powervision that will auto tune and then slide you some good mufflers like some Crushers or the 4" Rineharts or some 2.25" baffled Rush Mufflers and you'll be good to go.
Why tune it you ask, I know you think the bike runs fine or seems to but be realistic, look what you just removed from your head pipe, there's no way that thing will not run leaner than before, the engine is basically an air pump so the Air flow will increase through out the entire system without the cat to restrict the flow and it will not increase the afr enough to keep from running lean. Get a tuner or dynoed and you'll be happy.

I'd still get it tuned though!
