1-3/4in x .065 Tubing J - Mandrel Bend

The 1-3/4in x .065 Tubing J – Mandrel Bend from Stainless Works is a precision exhaust and intake manifold component engineered for fabricators, restorers, and performance enthusiasts building custom exhaust systems, turbo manifolds, and high-flow intake runners. This J-bend configuration is essential when you need to transition flow direction while maintaining structural integrity and aerodynamic efficiency.

Whether you're constructing a vintage hot rod exhaust, upgrading a late-model performance build, or fabricating a turbo installation, mandrel-bent tubing eliminates the wall collapse and turbulence created by traditional crush bends. Stainless Works manufactures this bend using the mandrel-bending process, which supports the inner wall during forming to preserve uniform wall thickness—critical for exhaust scavenging and pressure retention.

The 1-3/4-inch outside diameter with .065-inch wall thickness strikes the ideal balance between structural strength and weight savings, making it suitable for both street and performance applications. Stainless steel construction resists corrosion, withstands thermal cycling, and maintains dimensional stability under high exhaust temperatures. The J-bend geometry allows smooth, efficient flow transitions that reduce turbulence and backpressure—measurable advantages in dyno testing and real-world power delivery.
