Authentic USA-Made Heritage Construction:

Every Hi-Ram in the Nostalgic Series is cast and machined in the USA using the original sand-cast tooling that made these manifolds famous. Minor cosmetic variations are a natural characteristic of the traditional sand-casting process and are a genuine hallmark of Weiand's heritage craftsmanship — with no impact on performance or structural integrity. Weiand continues to produce these lower-volume manifolds with the original tooling to support the vintage, show, and nostalgia racing community.
