Can someone help me out. I thought I read somewhere that the muffler or system has a flapper valve in it. Is that true. And if so is it in the muffler?

Yup the 6.4 has a flapper in the muffler. The best way to get it out is to remove the entire giant muffler with something that will flow better!
I have this in my truck and love it

Are there any videos that demonstrate the exhaust note of these two kits?
I was looking at the one with the muffler, as I am not into loud exhaust any longer. Anything else a little quieter that these options?
There is a new muffler kit coming out from Magnaflow. This would be a little quieter than the MR400

Contact me if you want a quote on it and to pre order it. The Solo MR400 is in stock and ready to ship
When will these ship?
At the moment Magnaflow is telling us End of the month. If interested we can get you pre-ordered and I can ship it direct from Magnaflow to you as soon as its available.
All the videos in the link posted above, were those with the delete/muffler and the stock res still intact or removed? Thanks

Is that muffler bigger/more quiet than the one on the muffler kit?
I don't know for sure if the 2018 has it but I strongly suspect it does given FCA's consistent use of that design on all the 6.4L powered trucks and cars.
Was the flapper on the outlet side or the inlet side of the muffle. I had my exhaust shop cut the outlet side of the muffle. He checked and there was no flapper on that side.
Here is the stock muffler from my 6.4L 2500:
