"Catback" = everything from the CAT BACK.
Includes resonators or pre-mufflers, Y-pipe, and rear muffler.
If you wanted to have your entire exhaust sytem redone, sure you could do glass packs.
But they're old-school technology, they DO NOT increase flow - they flow for crap, and they break down rapidly.
The Nismo exhaust sounds a lot like that.
Get under your car and look at the exhaust configuration, it'll make more sense then.
