4in (101.6mm) O.D. 90 de gree Mandrel Bend

The Vibrant Performance 4-inch O.D. 90-degree mandrel bend is a crucial component for custom exhaust and intake manifold fabrication, particularly for performance-oriented vehicles. This product is designed for fabricators and automotive enthusiasts who require high-quality bends for their modified engine builds.

Mandrel bends maintain a consistent internal diameter throughout the curve, which is essential for preserving flow characteristics in turbo systems and high-flow exhaust headers. The precision tube bend is crafted using a form-fitting die that prevents wall collapse and maintains a uniform outer diameter along the entire 90-degree arc, ensuring optimal performance compared to cheaper crush-bend alternatives.

This component is particularly beneficial for mechanics and custom fabricators working on V8 swaps, LS platform conversions, and turbocharged four-cylinder builds. It is compatible with both mild steel and stainless steel systems, making it a versatile choice for various applications in street rod, drift, or race car setups.
