Doug's Headers H7066 U-Bend Mandrel Exhaust Tube 4 Inch Mild Steel

The Doug's Headers H7066 is a precision-engineered 4-inch diameter U-bend exhaust tube constructed from high-quality mild steel. This mandrel-bent exhaust component maintains consistent inner diameter throughout the bend, ensuring optimal exhaust flow and minimizing back pressure for improved engine performance.

Key Features:

• 4-inch outer diameter mild steel construction for durability and weldability
• Mandrel-bent design maintains uniform wall thickness and inner diameter
• 180-degree U-bend configuration for custom exhaust fabrication
• Smooth interior finish reduces turbulence and exhaust restriction
• Ideal for building custom exhaust systems, headers, and exhaust manifolds
• Compatible with standard exhaust welding and fabrication techniques

This U-bend tube is perfect for custom exhaust builders, fabricators, and performance enthusiasts who need reliable, high-quality components for their exhaust system projects. The mild steel construction allows for easy welding and modification to fit specific applications across automotive, hot rod, and racing builds.
