Vibrant 18284 180 Degree Mandrel Bend 1.625" OD 4" CLR Aluminum

The Vibrant Performance 18284 is a precision-engineered 180-degree mandrel bent aluminum tube designed for high-performance exhaust and intake systems. This U-bend features a 1.625-inch outside diameter with a 4-inch centerline radius (CLR), providing smooth, gradual bends that optimize airflow and minimize turbulence.

Key Features:

• 180-degree mandrel bent construction maintains consistent inner diameter throughout the bend
• 1.625" (1-5/8") outside diameter tubing for precise fitment
• 4" centerline radius provides smooth, gradual transition
• High-quality T6061 aluminum construction for strength and durability
• Polished finish ready for welding into custom exhaust or intake systems
• Mandrel bending process prevents tube collapse and flow restriction

Ideal for custom fabrication projects including turbo systems, intercooler piping, exhaust manifolds, and cold air intakes. The mandrel bending process ensures maximum flow efficiency by maintaining the tube's full diameter through the entire bend, unlike crush-bent alternatives that can restrict airflow and reduce performance.
