Headers are the best mod you can make for a street car. They add a ton of HP and torque and a better sound even with stock cat backs. You don't have to pay $1400 for Kooks...just call MarylandSpeed and they will hook you up with some Kooks for lots less. Kooks headers are very easy to install, so do it yourself and save additional money (I posted some videos of my install and you'll see for yourself). Be wary of oriental made headers...I've heard some pretty bad stuff about them and you can search C5 and see for yourself.
