3-1/2 x .065 Tubing 180 Degree Mandrel Bend

The Stainless Works 3-1/2 x .065 Tubing 180 Degree Mandrel Bend is a precision exhaust component engineered for custom exhaust fabrication and performance vehicle builds. This U-bend features a true 180-degree mandrel bend geometry, designed to optimize exhaust gas flow while maintaining structural integrity. The 3.5-inch diameter tubing with .065-inch wall thickness delivers the wall consistency needed for durability in high-temperature exhaust environments, while the mandrel bending process ensures smooth internal transitions that minimize flow restriction.

Constructed from 16-gauge stainless steel in natural finish, this bend resists corrosion and thermal cycling inherent to exhaust systems. The 6-inch leg length provides flexible integration into custom header and piping layouts, while the mandrel construction prevents the wall collapse and inner wrinkles common to crush-bent alternatives. Mandrel bending is the preferred method in professional exhaust work because it preserves wall thickness and maintains round tubing geometry throughout the bend, critical for pressure balance and scavenging efficiency in tuned exhaust systems.

This component is ideal for fabricators, restoration shops, and performance enthusiasts building custom exhaust systems for street cars, race applications, and specialty vehicles. It serves equally well in header fabrication, turbo piping, and custom mandrel-bent exhaust kits where smooth, efficient flow and corrosion resistance are non-negotiable. Stainless Works is recognized in the exhaust fabrication industry for consistent quality and precision bending, making this bend a reliable choice for builders who demand repeatability and durability in their finished systems.
