I haven't yet. But getting a tune would not hurt even if just changing the mufflers...These bikes run lean from the factory, so a tune would help. If you are changing both the mufflers and the air cleaner, or de-catting, a tune is necessary as you have opened up the air flow.
The only thing I have changed so far is the CFR slip ons, so have not done a tune yet.

It will run better with a tune...even if you left the stock pipes on. Now especially though.

If I've typed it once, I bet I've typed it 20 times...
The FIRST thing a man should do when considering making changes is GET A TUNER. It will help a stock bike, and when you change pipes and or air cleaner, you're ready for it.
Can you run without a tuner? Yes.
Will you blow your engine up running without a tuner? Probably not.
Can you expect to get 50,000 miles out of your engine without a tuner? Most likely.
Will it run correctly without a tuner? No.
Dealers and their parts and service departments are a business, in business to sell motorcycles, and motorcycle parts and accessories. They tell you that you can get away without a tuner, because a LOT of guys won't come off the jack for a tuner, and they're afraid they'll lose sales if they tell you to get a tuner.
Changing the air flow without changing the VE tables is not beneficial. These bikes run lean from the factory, adding a more free flowing exhaust makes them run more lean.
Do what you want, I won't criticize, just trying to offer things to think about.
...but there is a reason I won't buy a used bike as my primary ride...

It still needs to be tuned.
