the difference between resonators and cats?

2006 mustang gt... u7140... i'm currently running o/r x-pipes with no mufflers. i am about to get JBA shorty headers, but i don't it too get much louder. i was told that i could get hi-flow cats (of course) or resonators. besides the fact that cats are for emissions, what's the difference in the 2? anyone's answer will be appreciated.

resonators cancel out certain sound waves to improve sound in most cases. They can be used to quite things down as well. They usually get rid of alot of the raspy exhaust notes. If i were you i would put a set of high flow cats on it. There is no sense in taking them off, they flow well and keep the car from smelling like a gas station.

yeah i think that would be the biggest benefit to me... i just don't want to lose much of the sound, cuz i love the way it sounds now.

i'm going to put hi-flow cats back on... put i just got pulled over for defective mufflers, i wasn't planning on putting mufflers back on it cuz i love the way it sounds. could i put resonators on instead of mufflers???
