im looking for ways to improve gas mileage and perhaps performance but dont really want to go all crazy with turbos and the like. Do cold air intakes improve gas mileage, how bout catback exhaust systems, theoretically since air through your car flows smoother in one way and out the other, the gas mileage should improve right? i think these would be the mods i would get

Actually, they do mix, at least up to a certain point, any time you improve the efficiency, the net result will be better economy IF you drive it the same as before. the mileage you get depends on how you drive it. Yes you can have more power available, but the mileage will suffer only if you use that power to accelerate quicker or go faster than before. If you use the extra power to move the vehicle more efficiently, the mileage should improve, in other words it now takes less fuel to get up to cruising speed because you are using the same amount of fuel to make more power than before. Usually the mileage suffers because we are always sticking our foot in it to enjoy that extra power smile.gif However if you go with radical cam profiles or other serious mods, , you can get a lot more peak hp, but the fuel mileage will suffer, there is a curve involved,
As far as a cold air intake, they already are taking colder air from the fenderwell. maybe a free-flowing air cleaner element, smoother flowing piping to the air cleaner, synthetic lubricants in the engine/trans, a lot of little things can add up. A GT 5-speed should get around 30mpg in average driving.
