Hi, what is a header? What does it do? How much HP does it add? Is it worth it? I have a 2004 Honda Civic 2dr. LX. Does anyone know if there are headers for this car, and if so where to get it? Also, one last question, which kind? I've seen like race headers and 4-to-1 headers, that type stuff. If anyone has any answers to any of these questions, it would be greatly appreciated. Thanks.
