The intake will basically allow your Titan to breathe easier, thus (theoretically), produce more horsepower, torque, and better mpg.

No, it can be installed by you.

The intake, and exhaust mod kind of go hand in hand. The intake allows more air to get into engine easier, while the exhaust allows more air out easier. All this creates more horsepower. It is a bit more technical then that, but I tried to tone the answer down a bit.
