45 Degree Brushed Mandre l Bend 4.00in O.D.

The 45 Degree Brushed Mandrel Bend 4.00in O.D. is a precision exhaust and intake tubing component designed for builders and fabricators who demand quality bends without compromise. This mandrel bend is essential for custom exhaust systems, intake manifolds, and intercooler piping where smooth, consistent radius turns prevent turbulence and flow restriction.

The design of this mandrel bend ensures that the inner radius of the tubing remains constant, maintaining wall thickness and internal diameter consistency across the entire 45-degree turn. The 4.00-inch outer diameter accommodates larger displacement engines and high-volume applications where flow capacity is critical. The brushed finish provides a professional appearance while protecting the substrate from corrosion.

Engine builders and enthusiasts restoring or modifying vehicles will find this component particularly beneficial. It eliminates the need for multiple fittings or adapters, reducing pressure drops and vibration that can degrade performance and longevity in demanding engine environments.
