Vibrant 321 Stainless Steel 180 Degree Mandrel Bend 2.50in OD x 3.75in CLR 18 Gauge Wall Thickness

This is a Vibrant 180-degree mandrel bend, made from 321 stainless steel with a 2.50-inch outer diameter and an 18-gauge wall thickness. It's designed for custom exhaust fabrication, especially when you're working with boosted engines or dealing with high operating temperatures. The 3.75-inch centerline radius gives you a smooth, consistent bend for your tubing runs.

You'll find that 321 stainless steel holds up better than 304 stainless steel when things get really hot, typically between 800°F and 1500°F. This makes it a solid choice for exhaust systems on turbocharged or supercharged vehicles where temperatures climb significantly. It also offers improved resistance to corrosion and is less prone to stress fractures compared to 304 stainless, which means your custom exhaust work should last longer under demanding conditions.
