Anyways, I understand now that Fujitsubo is high quality so assuming I went with the Authorize R Fujitsubo setup, could I also combine that with the STi Sports Muffler? Obviously after removing the Authorize R tips.

Basically the simplified exhaust system is as follows:
Engine -> Header -> Catalytic Converter -> Downpipe -> Muffler
Axleback just means it's basically just the muffler.
The STI Sport Muffler is designed to connect to the stock midpipe, where the connector is at the left side.
Here's a picture of the Sakamoto stock catback vs the Fujitsubo Authorize R catback system, see how the midpipe connections are different (Fujitsubo has a Y joint design approaching the muffler):
Me personally I would want a system with the least amount of joints as possible, less points of failure causing a leak.
Correct me if I'm wrong here, but JDM OEM optional exhaust has to meet JARI standards just like the stock car (gov emissions and noise requirements). JDM aftermarket exhausts are usually JASMA certified quality standard and it's probably not as stringent in terms of noise and emissions (then again I thought JASMA was created to get gov authorization to stay legit), but then you should get more gains in performance thru less flow restriction designs?
You can research these orgs to get a better understanding:
JARI - Japan Automobile Research Institute (gov partnership R&D with the high speed loop track you always see on Best Motoring)
JASMA - Japanese Automotive Sports Muffler Association (jointly created by a bunch of aftermarket manufacturers to set some standards)
