resonators

What are the purpose of the resonators? do they rob the car of power through restriction?

The one that the guy in the other thread used looks like a Aeroturbine Model # AR25.

The resonators shouldn't take any HP away from the car since it doesn't (or shouldn't) restrict air flow. They are simply there to reduce or change the exhaust note.

GM spent a lot of man hours and focus groups specifically on the sound of the factory exhaust looking for the "perfect exhaust note".

It's RESONATORS, and the purpose of them is to allow the car not to shake to death at certain RPMs. If you run a free exhaust, your car will resonate at certain RPMs due to sound frequency, the resonation will cause the car to shake.

I have no mufflers on my vette, but still have cats, and if I'm in 6th gear at 50-60mph the exhaust puts out a frequency that will rattle the vette.

resonators, and they are usually used to help quite the car down a bit.

resonator

n. (rěz'o-nā'tor)

acoustical device for reinforcing sound, as the sounding board of a piano, the "belly" of a stringed instrument, the air mass of an organ pipe, and the throat, nose, and mouth cavities of a vocal animal. In addition to augmenting acoustic power, resonators may also, by altering relative intensities of overtones, change the quality of a tone.

All other posts probably should have stopped with this one. Perfect explanation.
