Glass Packs for resonators ??

I have a set of Big Boar ceramic coated dual chamber mufflers, they sound IMO great when I stomp it or even idling, but running down the highway at 70 the noise is not good, it's not drone just very loud, wondering if I were to install a set of small glass packs in the tailpipes like resonators would that quiet it down?? would they fit?? has anyone done this?? thanks
