yeah sorry resonators are always exposed to exhaust gasses they don't go over the existing pipe if this is what you believe suck it up your wrong harsh i know, and filled resonators always break down the "mufflers" on most z aftermarket exhausts are all fiber filled and even on an n/a they get louder after the first week thanks to breakdown.
A lot of the performance straight through's are filled too you have to be careful when buying if you don't want a filled one. they resonators that are y'd into the exhaust are more like true resonators by definition as they are mainly hollow and due to resonant frequencies at like a spring when tuned correctly to produce inverted amplitude sound waves that travel back up the y and cancel some of the sound waves in the main exhaust pipe out. the fiber filling in some resonators acts like a damper and absorbs the sound furthering the frequency range the resonator is capable of affecting.
