The Vibrant Performance 2.5in O.D. Titanium 90 Degree Mandrel Bend delivers the flow characteristics and weight savings that serious exhaust fabricators demand. This Grade 1 commercially pure titanium bend features a 3-inch centerline radius and maintains consistent wall thickness throughout the bend radius, eliminating the restrictions and turbulence created by crush-bent tubing. For builders working on high-performance street cars, track machines, or weight-sensitive motorsport applications, this mandrel bend provides the foundation for exhaust systems that flow freely and shed pounds where it matters.
Mandrel bending keeps the tube's interior smooth and round through the entire bend, preventing the oval deformation and wall thinning that compromise flow in standard bent tubing. Vibrant Performance manufactures this bend from CP1 titanium, which offers roughly 40 percent weight reduction compared to stainless steel while maintaining excellent corrosion resistance and high-temperature stability. The 2.5-inch outside diameter fits common performance exhaust sizing, and the 90-degree bend angle handles tight routing around chassis components and suspension members. Each bend arrives ready for welding into custom cat-back systems, turbo downpipes, or complete header-back builds. The precise mandrel process ensures the bend matches up cleanly with straight tubing sections and other fabrication components.
This titanium mandrel bend suits applications where both performance and weight matter. Road racers, time attack competitors, and drag racers choose titanium exhaust components to reduce unsprung weight and lower center of gravity. Street builders appreciate the corrosion resistance and distinctive appearance of titanium tubing. Pair this 90-degree bend with Vibrant's straight titanium sections and V-band clamps for a complete lightweight exhaust solution.

Mandrel bending uses an internal support that keeps the tube round throughout the bend radius. This maintains consistent inside diameter and smooth airflow, while crush bending creates an oval cross-section that restricts flow and causes turbulence. For exhaust applications, mandrel bends can improve flow by 25 percent or more compared to crush-bent alternatives.
Titanium weighs approximately 40 percent less than stainless steel while offering comparable corrosion resistance and higher temperature tolerance. For performance applications where weight reduction matters, titanium exhaust components reduce overall vehicle weight and lower the exhaust system's contribution to unsprung mass.
TIG welding with pure argon shielding gas is the standard method for titanium exhaust fabrication. The weld area requires complete argon coverage on both sides of the joint to prevent oxidation and embrittlement. Many fabricators use purge dams or back-purge fixtures to protect the inside of the tube during welding.
Yes, titanium can be welded to stainless steel using proper techniques, though many builders prefer to keep material types consistent throughout the system. V-band clamps provide a mechanical connection option that allows mixing titanium and stainless components without welding dissimilar metals together.
