I drilled mine out a couple of weeks ago too. Just the cap at the end of the baffle with a 1 1/8" hole saw (bit) from Lowe's. BTW, couldn't get a 1 1/4" bit to fit.
The '14 exhaust is catted but there's plenty of room between the cap and the cat. Just be careful when the drill punches through so you don't slam the cat. I thought about taking the cat out too but it sounds good enough with the cap gone.

So I did this on my '16 48, you can pick up a cheap 3/4" step drill bit and 12" extension from harbor freight for less than $20. Works perfectly. I started small and worked my way up to 3/4". Definitely got louder and deeper, I could finally hear the bike at speed, however it was not loud enough for me so I bought a 1-1/4" hole saw bit to remove the entire baffle. IMMEDIATELY REGRETTED IT. Yes it got louder but it changed the tone entirely and doesn't have a typical Harley sound, it's strange, I don't even know how to describe it. And the decel popping is RIDICULOUS. I personally would not go above 3/4" holes in the baffles if I had to do it again.
I had to go to home depot to find something to kinda close it off real quick like, so I picked up these 5/8" brass flare nuts - drilled and tapped then installed in the mufflers and it got it back close to where it was with roughly allowing 3/4" airflow. Even with loctite and lock washers they vibrated out. So I had to remove the heat shields and drill it from the side, completely through both sides the muffler with longer screws...and anyways...
Lots of trouble I went through lol.. but I cannot recommend enough to not go too big. A 3/4" hole sounds GREAT until you can get something better.
