Okay so I'm pretty good with cars but I've always been confused with exhaust systems so I'd like someone to explain this to me even though it's probably a stupid question.... Also I drive a 2001 Mustang GT. So what are cats? What is a catback exhaust system vs I guess a normal exhaust? And does an O/R X-pipe eliminate the cats, resulting in more sound? Lastly, are resonators and mufflers the same thing or does the resonator come right after the cats? Thanks guys!

cats = catalytic converter, to reduce emissions.
catback exhaust system = exhaust system from behind the cat, leaves the converter in place, replaces muffler(s) and tailpipe(s).
x and h pipes, easier to just google it.
resonator normally behind muffler, helps to reduce certain sound waves.
