45 Bend Stainless 2.500 x 4in Radius 16 Gauge

The Patriot Exhaust 45 Degree Bend Stainless 2.500 x 4in Radius 16 Gauge exhaust pipe is a precision mandrel-bent component engineered for custom exhaust system fabrication and restoration work. This 45-degree exhaust bend delivers the smooth internal geometry required to minimize turbulence and backpressure in high-flow exhaust systems, making it an essential component for performance exhaust builds across automotive applications.

Built from 16-gauge stainless steel, this bend offers excellent corrosion resistance and durability in engine bay environments. The mandrel-bent construction maintains consistent wall thickness and internal diameter throughout the bend, preventing the kinking and flow disruption that can occur with cheaper dies-bent alternatives. With a 2.5-inch diameter and 4-inch bend radius, this component fits standard performance exhaust tubing specifications and accommodates moderate-radius bends necessary for engine compartment routing. The 6-inch legs on both sides provide ample material for welding into complete exhaust systems or adapting to existing piping.

This exhaust bend is purpose-built for exhaust system builders, hot rodders, performance tuners, and restoration specialists who demand quality mandrel-bent components. Whether fabricating a complete custom exhaust from the ground up or replacing damaged OEM piping with performance-grade stainless alternatives, this bend provides the structural integrity and flow characteristics necessary for reliable operation. Patriot Exhaust components are widely used in both street performance and motorsports applications where exhaust flow optimization directly impacts engine efficiency.

Mandrel-bent stainless exhaust bends have become the standard in custom exhaust fabrication because they preserve airflow while offering superior longevity compared to mild steel alternatives. Stainless construction resists rust and thermal cycling damage, making these components suitable for both daily drivers and high-heat performance vehicles. This 45-degree bend with its moderate 4-inch radius strikes a balance between compact routing capability and smooth flow characteristics.
