2-1/2in x .065 Tubing J - Mandrel Bend

The Stainless Works 2-1/2in x .065 Tubing J-Mandrel Bend (MBJ250-H) is a precision exhaust component engineered for custom exhaust system fabrication and modification. This 180-degree mandrel bend maintains consistent tubing diameter throughout the bend radius, eliminating the wall collapse and turbulence that occurs with standard bending methods. The 2.5-inch diameter tubing accepts common exhaust piping while the mandrel-bent construction preserves optimal exhaust gas flow dynamics.

Built from 16-gauge stainless steel in a natural (mill) finish, this J-bend features 6-inch and 15-inch legs, providing configurable spacing for exhaust routing through engine bays, transmission tunnels, or frame rails. The stainless construction resists oxidation and corrosion from high-temperature exhaust gases and atmospheric moisture, critical for longevity in both street and performance applications. Mandrel bending—the process of bending tubing around a removable internal form—ensures consistent wall thickness and internal diameter, reducing backpressure compared to crimped or crushed bends.

This component is essential for fabricators, restoration shops, and serious enthusiasts building or modifying custom exhaust systems on muscle cars, hot rods, trucks, and performance vehicles. Custom exhaust work demands precision bends that don't restrict flow or create stress points; mandrel bending delivers both. Each bend arrives ready to integrate into a larger exhaust assembly or to serve as a replacement section in an existing system.

Stainless Works is recognized in the automotive aftermarket for precision mandrel-bent exhaust components and complete exhaust systems. The 2-1/2-inch diameter is a popular sizing for mid-displacement engines and modern performance platforms, striking a balance between flow capacity and package constraints. Weigh approximately 3.95 lbs and measure 10.05 x 2.5 x 17.35 inches, making it easy to handle and ship.
