Mild Steel Bent Elbow 3.500 90-Degree

The Mild Steel Bent Elbow 3.500 90-Degree from WOOLF AIRCRAFT PRODUCTS is a precision exhaust bend engineered for serious engine builders and custom automotive fabricators. This 90-degree elbow serves as a critical connector in high-performance exhaust systems, turbo manifold assemblies, and custom intake or coolant routing applications. Whether you're developing a show-stopping street engine, turbocharged build, or prototype vehicle, this mandrel-style bent tube provides the flow characteristics and structural integrity required for reliable long-term operation.

Manufactured from mild steel with a 3.500-inch outer diameter and a 3.5-inch centerline radius, this component is constructed to 16-gauge specifications and arrives in natural (uncoated) finish. The 90-degree geometry and consistent radius bend minimize turbulence and pressure loss, delivering superior flow compared to welded or crushed alternatives. At 2.32 pounds, the bent elbow is light enough for weight-conscious builds while maintaining the wall thickness needed to withstand high exhaust temperatures, boost pressure spikes, and thermal cycling without warping or cracking. The precision mandrel bend preserves internal diameter consistency throughout the curve, which is essential for maintaining velocity and scavenging efficiency in modern engine designs.

This bent elbow is ideal for fabricators building custom exhaust systems, intercooler piping, or complex engine bay routing where off-the-shelf components won't fit. The natural steel finish allows for easy welding, painting, or ceramic coating to match your aesthetic and thermal requirements. Commonly paired with flanges, couplers, and additional mandrel bends to create complete exhaust or cooling circuits, this WOOLF AIRCRAFT PRODUCTS component delivers aircraft-grade bend accuracy at a price point accessible to serious enthusiasts. Verify your tube wall thickness and diameter requirements before ordering; this 3.5-inch diameter elbow is sized for larger displacement engines and high-flow applications where standard 2.5 or 3-inch systems fall short.
