If you decide to go race headers then be prepaired to possibly fail inspection. That being said, putting headers on can lead to exhaust leaks if the gaskets don't hold and possibly y-pipe leaks as well. You'll need some heat wrap to protect some of the wiring, plug wires and possibly the fuel and brake lines under the car where the y-pipe will almost touch them. You will need a tune to remove the check engine light for the missing EGR and AIR if you go race headers, and to tune out the rear O2 sensors. If your motor mounts are worn, your headers or y-pipe will most likely hit the A-arm or floorboard when you accelerate. Plan on getting new front O2 sensors as well but don't put them in right away as new headers can burn off the coating or oily residue and foul out the O2 sensors. Overall, the header install can run around $1000 even if you install them yourself if you swap out other parts like the O2's, plug wires, motor mounts, gaskets, tune, plugs, heat wrap, etc.
