180 Degree Mandrel Bend 1.75in O.D. 16 Gauge SS

The 180 Degree Mandrel Bend 1.75in O.D. 16 Gauge SS from VIBRANT PERFORMANCE is a precision exhaust component engineered for custom automotive builds where smooth, high-flow header and exhaust routing is non-negotiable. Whether you're fabricating a full custom exhaust system, installing a turbo manifold, or rerouting coolant and intake piping, this mandrel bend delivers the structural integrity and airflow efficiency that separates professional work from amateur modifications. Mandrel-bent tubing maintains consistent wall thickness through the curve, eliminating the kinks and restrictions that crush tubing creates.

Constructed from 16-gauge stainless steel, this bend features a 2.625-inch radius with six-inch legs on each side, allowing seamless TIG or MIG welding into custom manifolds or pipe assemblies without stress-riser defects. The 1.75-inch outside diameter fits most street and race exhaust applications, from four-cylinder turbocharged platforms to V8 builds. Stainless steel resists corrosion, thermal cycling, and exhaust gas degradation far better than mild steel, making it the choice for durability in harsh underhood environments. The mandrel-formed geometry minimizes turbulence and backpressure loss, critical for maximizing scavenging efficiency in high-performance exhaust systems.

This bend suits fabricators, performance shops, and experienced DIY builders who are laying out custom exhaust manifolds, turbo downpipes, or intake runners where off-the-shelf bends don't align with their design. The neutral stainless finish requires minimal finishing before welding and integrates cleanly into aesthetic engine bays. Installation demands proper TIG welding technique and jig alignment to ensure symmetrical flow paths; amateur stick welding or poor joint preparation will compromise both flow and longevity. Compatible with most fuel types and engine platforms, this component is ideal for builds prioritizing flow efficiency and corrosion resistance.
