Show original supplier description
The Hooker Headers Competition Header (part number HKR3902-1) is engineered for optimal performance and durability in Oldsmobile V8 powered GM A-Body and B-Body vehicles manufactured between 1965 and 1975. These headers boast 1.75-inch primary tubes and a 3-inch collector, designed to efficiently manage exhaust gases and enhance engine breathing. Constructed from robust 16-gauge steel, these competition headers are finished with a metallic ceramic coating. This high-heat resistant coating not only contributes to longevity but also aids in thermal management, helping to keep under-hood temperatures down. The product description highlights that the coating is heat-cured and highly resistant to heat, offering a durable solution for high-performance applications. Hooker Headers has a long-standing reputation in racing, claiming to be the winningest header in drag racing history. The product comes as a pair and includes gaskets and hardware for installation. Vehicle applications specifically include the Oldsmobile Cutlass (1965-1975), Cutlass Salon (1975), 442 (1965-1971), Vista Cruiser (1971-1974), and Delta 88 (1971-1975).
