3In Header Reducers (2) Pair

The 3 In Header Reducers (2) Pair from Racing Power Co-Packaged delivers a proven solution for custom exhaust system builders and engine swap enthusiasts who need to transition oversized collector outlets to smaller diameter piping. These reducer cones are essential when matching modern high-flow headers with existing exhaust components or installing period-correct systems on modified powerplants. Available as a pair, they eliminate costly custom fabrication and ensure proper exhaust flow dynamics across your entire system.

Constructed from aluminized steel, the 3 In Header Reducers feature a three-bolt flange design that integrates seamlessly with standard header collector patterns and exhaust manifold configurations. The precision-engineered taper transitions a 3-inch inlet to a 2.25-inch outlet diameter, maintaining smooth flow characteristics while minimizing turbulence and backpressure spikes that degrade horsepower and throttle response. Aluminized construction provides corrosion resistance and heat reflection, extending component lifespan in high-temperature under-hood environments where traditional steel would degrade rapidly.

Street machine builders, LS engine swap specialists, and vintage hot rod fabricators rely on these reducers when bridging collector sizing gaps without cutting and welding custom transitions. The three-bolt flange mounting accommodates both header collector ports and mid-pipe connections, making them versatile for carbureted and fuel-injected applications alike. Whether you're downsizing from modern big-block headers to classic 2.25-inch systems or optimizing mid-range torque delivery on a crate engine installation, this pair provides the structural integrity and thermal stability demanded by serious performance work.
