Vibrant 13059 90 Degree Mandrel Bend 4 Inch O.D. Aluminum Tubing

The Vibrant Performance 13059 is a precision-engineered 90-degree mandrel bent aluminum tube designed for custom exhaust systems, intercooler piping, and intake manifold fabrication. This mandrel bend features a 4.00-inch outside diameter and maintains consistent wall thickness throughout the bend, ensuring smooth and unrestricted flow without the crimping or collapsing common in crush-bent alternatives.

Key Features:

• 90-degree bend angle for versatile routing options
• 4.00-inch outside diameter for high-flow applications
• Mandrel bent construction maintains uniform inner diameter throughout the bend
• T6061 aluminum construction provides excellent strength-to-weight ratio
• Smooth interior surface optimizes airflow and reduces turbulence
• Compatible with standard 4-inch exhaust clamps and couplers
• Ideal for turbo systems, exhaust fabrication, and custom intake builds

Mandrel bending is the preferred method for performance applications because it prevents the tube walls from collapsing during the bending process, maintaining maximum flow capacity. This Vibrant Performance bend is perfect for fabricators and enthusiasts building custom exhaust systems, turbocharger piping, or air intake systems where flow efficiency and precise fitment are critical.
