3.5in Oval 90 Degree Man drel Bend

The 3.5in Oval 90 Degree Mandrel Bend is a precision-engineered exhaust component designed for custom exhaust fabrication and high-performance vehicle modifications. Built for welders, fabricators, and automotive enthusiasts who demand clean, smooth bends without kinking or wall collapse, this mandrel bend serves as a critical foundation for constructing efficient exhaust systems. Whether you're building a street performance exhaust, a competition rig, or restoring a classic with modern flow characteristics, this component ensures your bends maintain consistent interior diameter and structural integrity.

Manufactured from 16-gauge stainless steel, this mandrel bend features a 5.25-inch radius and 6 x 6-inch legs, offering optimal flow dynamics for mid-sized exhaust systems typically found on V6 and small-displacement V8 applications. The mandrel bending process prevents the inner wall from collapsing during the bend, which is essential for maintaining exhaust scavenging efficiency and minimizing turbulence that would otherwise rob horsepower and increase backpressure. The 90-degree angle accepts both intake and discharge piping configurations, making it versatile for primary collector design, turbo downpipes, or intermediate system routing where space constraints demand tight geometry.

This bend suits fabricators, performance shops, and serious DIY builders tackling custom exhaust systems on trucks, muscle cars, and modified street machines where 3.5-inch tubing is specified. Stainless steel construction resists corrosion and thermal cycling, ensuring longevity in aggressive driving conditions and marine environments. Installation requires welding to adjacent piping sections; ensure proper fitment to your system's overall layout before committing to welds, as the 5.25-inch radius and 90-degree angle define clearance and component spacing in your final assembly.
