Stainless Bros 1.88in SS321 45 Degree Mandrel Bend Elbow 1D - 16GA/.065in Wall - w/ Leg

What you get here is a single 45-degree mandrel bend elbow from Stainless Bros. It's made from SS321 stainless steel, which is a popular choice for exhaust systems because it handles high temperatures well. This particular elbow has a 1.88-inch outer diameter and a 1D bend radius, meaning the center of the bend is one diameter away from the tube's outer edge. It also includes a leg, which is a straight section extending from the bend, giving you more flexibility when fitting it into your custom exhaust setup.

The tubing itself is 16 gauge thick, or about .065 inches, which is a solid thickness for exhaust work. This helps it resist warping from heat and makes it strong enough to handle typical exhaust stresses. Mandrel bending means the tube keeps its round shape through the bend, unlike crush bends that can reduce flow. This is important for maintaining smooth exhaust gas flow, especially if you're building a performance-oriented system.
