A catback system is a compleat system that goes from your H-pipe(where your catilic converters or cats are.) back. It includs high flow mufflers and larger exaust pipe. The bigger pipe gives better exaust flow then just haveing better mufflers so you should see a better sound and power improvment. On the preformence side it works (and sounds) best with a better H=pipe and headers. (of course then you are talking a whole new exaust system and that can get pricy.
