iv here nothing but good about the 5zigen header one of the best on the market for the money.
i have that dc sports header and i really like it. i felt good noticible gains much better bottom end power. the fitment was as good as oem didnt hang low. alot of people say that they are bad for cracking witch i have not had a problem with yet. but i think that mite be the ceramic ones.
and iv herd that the greddy ones are crap crap crap but cant back that up as never used one.
opps!
forgot about HyTech Headers too.
If your EK is too low, you might have clearance problems I hear. So here is my (definative) list:
1. (Skunk2 not out yet ) Toda
2. HyTech
3. Buddy Club
But if you have to have one of the 3 you chose, 5Zigen.
