This is an easy project that anyone that knows how to turn a wrench can do.  If I count making my drill chuck, removing/reinstalling the saddlebag, cleanup, etc. it took me about an hour.  The trip to Home Depot was another 30 minutes.  The drilling process itself took about 15-20 minutes.  Removing the cc was priceless! 

You don't want to sell that bit do ya?  Prices have gone up in two years....

Just wondering if this would work on today's cats?

Assuming you're referring to a 2012 - 2013 touring model, yes.  The O2 sensors are different and have moved down the head pips but the cat is still in the collector.  Note the process above does not remove the cat entirely but drills a hole in it in the size of your bit.  There are posts about cutting the collector pipe and removing the cat entirely.

Anyone know if the header from a 2010 103" Ultra Limited  is the same as on the CVO 110"?  If so I could experiment taking out the cat from the one off the 103 and try it on the CVO and see if I like it.

I used Mr. Kerr's procedure on an '11 Ltd. header pipe for a friend.  The Ltd and CVO headers are the same.  to be certain, you might want to check the part numbers.

Yes, it can be done.  Assuming you remove and reinstall, a welding shop should be able to do it for you.  For the cost, however, you may want to consider a DX head pipe from Fullsac, one of the vendors here.
