It wont go down if you are daily driving. the only place you will notice a difference is at w.o.t.

It'll drop some because you'll be using it that much more. Human nature.

very true!

A freer flowing exhaust normally improves gas mileage since you're improving the efficiency of the engine....

The only difference will be that you'll hit boost at a lower RPM, which will decrease mileage a bit in those RPMs.

And like Defiant said, your foot will become heavier for some reason.

And you probably won't stay off the gas pedal once you hear it installed.
But no, you shouldn't see a huge difference in gas milage.
