Headers might give you just a little, very little more HP, mostly people install them for sound, and if you live in Calif, don't do it, and some other States

a header will give you more power than your catback....

i had a OBX header on mine and felt a huge difference! The stock header restricts airflow and hp, once i installed the OBX 4-1 race header my car actually pulled hard in 4th and 5th gear. I recommend it.
