since you cannot get cats seperate (orig. equip.) unless after market weld on, most companies sell you an X or H pipe with or without cats. therefore, your cat back set up connects from your H or X pipe after the cats. you have like a foot or so of intermediate pipe that is flanged and connects to your pipe before the muffler as well. the cat bac includes mufflers and pipe that run all the way back... hope that clears it up for you..
