Number of cats

From what i was reading everyone was talking about cutting off 4 cats from their 150's and replacing it with 2 hi-flows. When looking at/having my truck looked at we saw only 2. I have the 4.6L and was wondering if it only had 2 because of the engine and that the 5.4 came with 4. Or am i missing something here. thanks
