What do headers do?

Answer 1

Headers by design, smaller tubes at exhaust ports, actually create a vacuum which pulls spent gases from exhaust ports much faster than standard manifold that just lets gases flow through exhaust. In turn headers create more pull of air into intake usually increasing horse power and torque. Size of header tubing, smaller usually improves performance in low and mid range rpm, while the larger header tubing usually creates more power in upper high end of power range. Hope this helps.

Answer 2

In the context of computing and printing, headers are the areas of a document at the top, outside the normal printing area, where fixed data is printed. Things like the title or chapter of a book, the date, the page number, or something that is required on all pages are found there. They can be entered once and then repeated automatically on every page. Page numbers will change on each page, as will dates when printed. This saves the user having to repeatedly type the same thing on every page.

Answer 3

Headers provide information about the content of a document, such as titles, author names, and publication dates. They help organize and structure the document, making it easier to navigate and understand. In digital documents, headers can also be used for search engine optimization and accessibility purposes.
