1-7/8in (47.625mm) O.D. Tight Radius 180 Degree

The 1-7/8in (47.625mm) O.D. Tight Radius 180 Degree exhaust bend by Vibrant Performance is a precision mandrel-bent component engineered for custom exhaust system builders, fabricators, and high-performance automotive technicians. This U-bend serves as a critical transition piece in exhaust routing, allowing system designers to navigate tight engine bay constraints while maintaining optimal flow dynamics. Whether you're constructing a custom street rod, building a turbo manifold, or fabricating a competition exhaust system, this tight radius bend provides the geometric flexibility demanded by modern engine layouts without sacrificing exhaust gas velocity.

Manufactured from 16-gauge stainless steel, the 1-7/8in O.D. tight radius 180 degree bend incorporates a 3-inch radius and 5-inch legs for consistent wall thickness and structural integrity throughout the bend. The mandrel-bending process ensures the tube interior maintains uniform diameter without rippling, wall thinning, or obstruction—critical factors for maintaining backpressure consistency and preventing turbulent flow separation. The stainless steel construction resists thermal cycling stress, corrosion from acidic combustion byproducts, and vibration-induced cracking, making it ideal for both street and track applications where durability and repeated thermal expansion are operational realities.

This component is best suited for custom exhaust fabrication, turbocharger manifold construction, and header assembly where standard bends cannot navigate tight underhood geometry. Fabricators and hot rod builders working with 1-7/8-inch diameter tubing will find the tight 3-inch radius essential for achieving compact routing around engine blocks, transmission housings, and suspension components. Installation requires welding by a qualified technician using appropriate TIG or MIG techniques for stainless steel. Verify your system's tubing O.D. and bend radius requirements before ordering to ensure seamless integration with your exhaust design specifications.
