Depends on the age of the car. The only way to get both is to increase the efficiency of the engine, and on newer cars, the engineers pulled all the stops they could to get the maximum efficiency out of there. In some cases, a better flowing exhaust may help, but it's difficult to improve on what a company with a very large design budget already came up with. The only way to get both more speed and mileage is to take steps that the designers concluded were too costly to put on the production car.
So your best bet on a newer car is to do everything you can to reduce weight. Replace steel with fiberglass, carbon fiber, or aluminum. Remove things that you don't need if they are heavy enough to slow you down. See if you can find lighter batteries, wheels, and tires. They're out there if you look.
If it's an older car, you can update it with new technology, particularly if the basic design has been around a long time. For example, a '60s through '80s Chevy 350 can gain mileage if you replace the original cylinder heads with the '90s era Vortec heads.

You CAN get both economy and performance. As a matter of fact, a lot of after market parts help with this. A good place to start is with a Cold air intake. This draws in cold air which is more dense than the hot air from beneath the car. An exhaust system also helps. You might wanna try better spark plugs, maybe Bosch platinums. The gains in terms of both HP and Economy will probably be too small to notice if you get these parts individually. But if you install all these parts you may get a nice improvement. For gas mileage, a nice simple tip is check your tire pressure. If its too low, your mileage will GREATLY suffer.

Some mods improve efficiency, giving improved mileage and more power. Exhaust and intake mods allow air to move more freely through the engine at the cost of some additional noise. The better an engine allows airflow, from intake to exhaust, the more efficiently it runs.

Yes. Intake, like a cold air setup with a K+N airfilter and a better flowing exhaust system.

intake, header, exhaust, all these work if you go the speed limit...
