will the pacesetter header coupled with a high flow cat and intake increase my gas mileage at all ? I plan to do alot of long trips this winter looking to save a few bucks.

Yah, it should, more air in, more exhaust out.. But how much...that is for you to figure out
Everyones gain is different
True. But the most gains you will ever seen in gas mileage are from driving style. Besides a good tune up, most anything else will have very little effect. If you like ot get on it a lot, you will probably get worse gas mileage.

Will probably get an extra 0.1 mpg. Definitely shouldn't hurt gas millage.
im gonna get better gas mileage. I need a new converter anyway.

CAIs do nothing for fuel economy. A WAI will help your fuel economy, especially in the winter. The exhaust might help your fuel economy, but it will probably never pay for itself.

you won't see any real savings in gas, might see a drop because the nice extra torque you get with the header (at least on eco) makes you wanna hit the go pedal more.
The parts shouldn't be purchased as an attempt to improve gas mileage. Driving style will have the greatest impact.

Cold air intakes will do nothing for fuel economy because our cars run in closed loop mode. Additional air will be met with additional fuel. For those who say less restriction = more efficiency, did you forget about the throttle plate? That's where 99.9% of your restriction comes from. Take the throttle plate out of the equation by flooring the car, and yes, the intake matters for power, but a CAI will do you no favors for fuel economy. If you have any concern for fuel economy, you won't be flooring your car anyhow.
Warm air intakes increase economy at the cost of power. Ever wonder why MPG decrease in the winter? Intake air temperature is a part of it.
-Fuel atomizes better in warm air allowing for leaner, more even mixtures. (ex: Hondas won't go into lean-burn mode when it's cold out)
-Throttle opens wider for the same power, warmer air is less dense, so pumping losses are reduced a bit.
-Drawing in warm air reduces warmup time (cold engines use more fuel).
Some cars came with both a WAI and CAI system so they can regulate their intake air temperatures. Some Acuras actually have a heater core in the air box to heat the incoming air.
The amount of work the engine has to do on the intake stroke is decided largely by manifold vacuum, which is determined by where your foot is. The resistance on the exhaust stroke is determined by how freely your exhaust system flows. If you're driving for maximum economy at partial throttle, you're not really pumping exhaust gases beyond what the stock exhaust system can handle. For this reason, I say an exhaust system probably won't pay for itself in fuel savings.
The best fuel efficiency mod here (one that will pay for itself somewhat quickly) is the WAI. Attach a compact cone filter directly to the throttle body and call it a day.
Most car manufacturers don't bother with a warm air system because the EPA doesn't test fuel economy in freezing weather, so any benefits from the WAI wouldn't show up in the EPA's advertised MPG numbers (and it would make the car more expensive). Also, it would knock down horsepower a bit.

Or do what I did.... drop the IAT sensor in the engine bay.... instead of relocating it to the front of the car
