Few companies have been doing headers for classic Mustangs for as long as Hedman Hedders. Hedman has been around since the early 1950s and prides itself on producing some of the best headers in the industry. More than 50 different types of headers are available for '65-'10 Mustangs. This is the full-length Elite ceramic-coated header with 1 5/8-inch diameter primary tubes for '65-'73 Mustangs. They feature a fail-safe ball and socket collector to eliminate collector gasket concerns.
