What is the difference between headers and extractors?
None! In Australia, headers were known as extractors through the 60’s and 70’s by the pioneering companies that developed them. In America at the same time they were coined headers (also spelt hedders). This was in part due to the fact that they (headers) are an extension of the cylinder head. In the 80’s new Australian companies, along with the established industry, began to market extractors as headers. The main reason being that these companies intended to change the image of the humble extractor to more of a common vehicle replacement component. Some ‘old school’ enthusiasts still call them extractors today.
