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.
there's a good video test of stock/shortie and long headers on You tube, they carefully dyno them and found that the 4 into one worked best by far.They can be tuned for where they'll help by varying the length of the primaries..
