Cat-back= Madreal bent piping come in whatever size you want, For instance, accents use 2 inch piping because they dont put out that much exhaust, Elantras use 2.25 or 2.5 same for the tiburon. If you were turboed or using any other aftermarket engine parts you would get 3.0 inch piping Your regular piping is small, Some people get catbacks for performance while others like them just because they make your car louder
