I'd bet that with the combination of intake, exhaust, and a tune, you could easily add 15% or more to the HP and torque. On one of my other cars, which started with about the same HP as a 4.4, I was able to achieve way more than 15% improvement with just simple N/A mods. Those mods included intake, headers, cat back exhaust, intake plenum and elimitating the intake baffle. I had free flow cats, which added even more power, but they were too loud. The sum of those mods is way over $1k though. The headers for that car's V6 were $1,500 alone, the exhaust another $1,500.
I don't think this would be insignificant; it would put you very close to 4.6i power with your 4.4. Your but-dyno would definately feel the difference, and throttle response and sound woud be much better.
Then again you just could sell your 4.4, and buy a 4.6 for about $2-3K more, (given equal mileage and condition). Given the cost of modding a 4.4 to the hilt N/A, it would probably be cheaper.
