CAI/Tune is hands down the best bang for the buck on a new 5.0, GT or Boss. Should be everyone's first mod apart from tires.
X-Pipe comes in second.
It's not that headers won't give you gains. They absolutely will. But for the cost of them, the hassle of the install, and the fact that they will leak at some point in the future, it's a question of cost/benefit.

I agree with the tune and CAI being first.
As far as your opinion on headers, I don't. When you get well engineered/higher quality headers and have them professionally installed, even though on a Mustang they are pathetically simple to install. They will last as long any stock exhaust system without leaks. I only use American Racing headers on all my personal cars and customers' cars and we've never had header leaks. On a 5.0 untuned I personally saw a difference of over 25 rwhp.

Even Kenne Belle has said they do not recommend headers on the GT500 or other FI cars because the leaks that are guaranteed to develop wreak havoc with tuning A/F ratios at high boost.
If you don't believe me or Kenne Bell, just Google "header leaks". 4,460,000 results returned.

Well Ford wanted long tubes
okay so if long tubes will not net any benifit then why did a Ford Engineer state "We would have used long tubes but could not push the cats any further back"?

No one in here is saying you won't gain any horsepower from long tubes. Obviously you will. What I said was when you look at a gain of 15-20 hp versus the cost, hassle of installation, and headaches down the road from leaks that IMO they're not worth it. Definitely not where I'd start with mods anyway.
