not to sound like an ass, but this topic has pretty much been beaten to death in the past...
and just so people wont be able to whine cuz 'i'm such an ******* for telling someone to not be lazy', i searched zetec performance chat with 'best race header'... after 4 minutes of searching:
all of these are less than 3 months old... there's many more the further back you go...
repeat after me: the search button is my friend, the search button is my friend
hope this helps man.. good luck
