Vibrant 321 Stainless Steel 90 Degree Mandrel Bend 3.00in OD x 4.50in CLR - 16 Gauge Wall Thickness

This 90-degree mandrel bend is made from 321 stainless steel, which handles prolonged high temperatures, from 800°F up to 1500°F, much better than standard 304 stainless. That makes it a solid choice for custom exhaust systems, especially for forced induction builds where exhaust gas temperatures can get really high. The 16-gauge wall thickness, which is about 0.065 inches, offers a good balance of strength and workability for fabrication.

The mandrel bending process ensures the tube maintains its shape and diameter through the bend, preventing kinks or restrictions that could hurt exhaust flow. This particular bend has a 3-inch outer diameter and a 4.5-inch centerline radius, giving you a smooth, consistent curve to work with when you're routing your exhaust system. It also has superior corrosion resistance and is less likely to develop stress fractures compared to 304 stainless steel.
