^ Crank pulley and header are nice upgrades, I just did both of those last week. the pulley will help the engine spoil or rev better and easier and the header will help it exhale better thus increasing horse power. I can feel the difference in my car and the header also adds some higher rpm noise from where you can hear the exhaust rushing through it but after an axle back and a CAI it isn't easily noticeable. some ECU rests and some getting used to and my cars estimated whp will be between 106 and 112hp and fuel inefficiency will be creaping up on the 50mpg range average, right now i can get that high way easy will maintaining speed limits. I would suggest looking and seeing what stock header you have first and if you have one like mine in my

then get the pulley instead and hold off on the header but, if yours is like
Tooter's

then get the header. i suggest megan racing, biggest diameter and MI has a great price on it, also bet the stud kit it makes the install nice.
