2005 V6 Purchase Advice

[fd06stang]

I'm looking at buying a 2005 Ford Mustang V6 with low miles. I was looking for a stock one but this has a few modifications I need advice on. It has a Ford Racing Cold Air intake on it - is this a good modification to keep or should I go back to stock? Also, it has a loud single exhaust - would I be able to swap out a stock exhaust or is there anything else involved? What else should I be looking for?

CAI won't hurt anything to leave on, probably doesn't make any difference performance-wise. Changing back to stock exhaust shouldn't be a big hassle either.
