Our range of mild steel mandrel bends is designed to provide fabricators, exhaust builders and performance enthusiasts with high-quality components for custom exhaust systems and fabrication projects. Whether you're building a street car, race car, drift car, turbocharged vehicle, 4WD or diesel exhaust system, our mandrel bends provide the flexibility needed to create professional results.

Unlike traditional crush-bent tube, mandrel bends maintain a consistent internal diameter throughout the bend. This helps improve exhaust flow, reduce restriction and create a smoother path for exhaust gases. The result is a cleaner finished product and improved performance potential.

We stock a wide range of bend angles including 15°, 30°, 45°, 60°, 90°, 135° and 180° bends, allowing fabricators to create everything from simple exhaust repairs through to complete custom systems. Available diameters range from 1" (25.4mm) through to 6" (152.4mm), making them suitable for headers, motorcycle exhausts, street performance vehicles, turbo systems, diesel applications and motorsport fabrication.
