67-74 Bb Charger/Coronet

The 67-74 B-Body Charger/Coronet street headers deliver a direct bolt-on solution for 1.75-inch primary tubing with a 3-inch collector diameter, engineered for the Mopar B and RB-series engine platforms. These performance-oriented exhaust headers are purpose-built for classic muscle car restoration and high-output engine builds, providing the foundational flow characteristics needed to optimize exhaust scavenging on vintage Chrysler B-Body, C-Body, and E-Body vehicles spanning 1962–1974 model years.

Construction uses steel tubing with black paint finish, protecting against thermal cycling and corrosion inherent to street-driven classic vehicles. The 1.75-inch primary diameter is optimized for mid-range torque production typical of B and RB-series displcements, while the 3-inch collector transition minimizes back pressure and supports efficient exhaust exit velocity. This header pair includes gaskets and all mounting hardware required for installation, eliminating sourcing complications and reducing labor time during engine bay assembly or rebuild operations.

Restorers and hot rod builders targeting authentic performance upgrades on early Dodge Chargers, Plymouth Road Runners, and Coronet variants rely on these headers to improve exhaust flow beyond factory cast-iron manifold limitations. The black finish integrates visually with stock engine bay presentations while maintaining thermal durability. Weighing 29.95 lbs as a complete pair, the headers deliver a substantial upgrade path for street performance without requiring extensive modification to factory mounting points or adjacent systems on B-Body and C-Body platforms.
