Vibrant 13134 15 Degree Mandrel Bend 4.00" O.D. Aluminum Tubing

The Vibrant Performance 13134 is a precision-engineered 15-degree mandrel bend designed for custom exhaust and intake systems. This 4.00-inch outside diameter aluminum tube provides smooth, consistent airflow with minimal turbulence thanks to the mandrel bending process that maintains constant pipe diameter throughout the bend.

Key Features:

• 4.00-inch outside diameter for high-flow applications
• 15-degree bend angle for gradual directional changes
• Mandrel-bent construction maintains consistent wall thickness and inner diameter
• T6061 aluminum construction for excellent strength-to-weight ratio
• Polished finish for professional appearance
• Compatible with standard 4-inch exhaust and intake components

Mandrel bending ensures the tube maintains its full 4-inch inner diameter throughout the curve, eliminating restrictions that crush-bent tubing creates. This results in maximum flow efficiency and performance. Ideal for building custom turbo systems, exhaust fabrication, intake piping, and intercooler plumbing where precise angles are required.
