Previously obsolete, these 1964-66 Mustang High-Performance Exhaust Manifolds are now available by Scott Drake. Engineered exactly like the original for longevity and trouble-free installation. These authentic cast iron reproductions feature correct markings and raised part numbers for early high-performance cars, but will work well on all 1964 - 1973 small-block Mustangs. Includes exhaust manifold studs and nuts for a proper installation to the H-pipe. 2" diameter outlet.
