Exhaust Manifold for Ford Galaxie (1965-1966) 260 289 302

T304 Stainless Steel Shorty Headers for 1965-1966 Ford Galaxie (Windsor V8)

These shorty headers replace the restrictive factory cast iron exhaust manifolds to improve exhaust scavenging and lower under-hood temperatures.

The Stock Galaxie Cast Iron Bottleneck

The OEM cast iron exhaust manifolds on the 1965-1966 Galaxie were engineered for mass production and clearance, not volumetric efficiency. Over decades of thermal cycling, these heavy cast components warp and crack, causing critical exhaust leaks. Furthermore, the rough internal casting flash and sharp directional changes create severe backpressure. This restricts the 289 cubic-inch engine's ability to evacuate spent gases, resulting in elevated cylinder head temperatures, compromised mid-range torque, and significant engine bay heat soak.

The Engineering Solution

Upgrading to these shorty headers resolves factory restrictions while maintaining a compact footprint. Manufactured from mandrel-bent 304 stainless steel, the 1-5/8" primary tubes provide a smooth, continuous path that dramatically increases exhaust flow velocity and optimizes cylinder scavenging. Thick 3/8" steel flanges resist thermal warping, ensuring a permanent, leak-free seal against the exhaust ports. Terminating in 3" collectors, they significantly reduce backpressure. Crucially, these headers clear common swap hurdles, seamlessly accommodating Ford GT-40 "P" heads, AOD transmissions, and factory power steering setups without requiring structural chassis modifications.
