slp was in reference to the mufflers, although you have many choices, that was just one of the louder ones. After the x or h pipe you need to choose a cat-back set-up and mufflers. Basically it goes headers, x or h pipe with or without cats, flow tubes (which are part of the cat -back), mufflers, tailpipes. On my system flow tubes, mufflers, and tailpipes were all included as the cat-back(converters back). Hope I didn't confuse you more.
