I have the magnaflows they are quiet and no drone but when you get on it, it wakes up and growls like hell.

I have GT500KR mufflers. Love the sound. Get a lot of compliments. only a little bit of drone below 1300 rpm when the car is first started and the engine is still heating up.

+1 to the FRPP/Borla Stingers. Love the rumble that they produce. I can always tell my car when I'm not in it.

I can answer that the car definitely only has 2 cats, because that's the exact same car I have.

As long as the catted x-pipe keeps the O2 sensors in the stock locations you should not have a problem as far as I know. I threw codes whenever I switched to the long tube headers that moved the locations of the O2 sensors downstream and therefore threw codes for being slow to respond (warm-up). My tuner changed my custom tune to ignore these for me, or basically turn the downstream sensors off.

Ultimately I think you need to check with the x-pipe manufacturer and verify that it does not change the locations of the O2 sensors from the stock pipe.

Upgraded my exhaust in late October. Now running American Racing Header Long Tubes, Catted X-Pipe and 3" Magnaflow cat backs with Magnapacks. Much louder to say the least over the FRPP GTA's.

Steeda axle backs... They have no drone whatsoever, and a little different sound than most mustangs you encounter on the street. I have a video that i feel has a good representation of what they actually sound like.

Installed Ford Racing Axlebacks and my '14 GT sounds the way it should have - real muscle! Also; much depends on where you live. If you live in an area that uses salt on the roads to melt ice/snow during the winter (I drive my Stang all year-round), then consider the "Marine" grade steel - 304 stainless steel - and not worry about rust.
