What is SS321 stainless steel?

SS321 is a type of stainless steel that includes titanium. This addition helps prevent carbide precipitation at high temperatures, making it more resistant to corrosion and cracking in demanding exhaust applications compared to standard 304 stainless steel.

What does '1D radius' mean for this bend?

A 1D radius means the center of the bend is one times the diameter of the tubing away from the tube's edge. For this 2.25-inch tube, it results in a relatively tight bend, which is useful for routing exhaust or piping in confined engine bays.

What is a mandrel bend?

A mandrel bend is created using a flexible internal support (a mandrel) that prevents the tubing from collapsing or kinking during the bending process. This ensures the inside diameter remains consistent throughout the bend, which is important for optimal exhaust flow.

About this part

Product Details

Stainless Bros is known for providing well-built stainless steel exhaust components. This 2.25-inch, 90-degree mandrel bend elbow is a prime example, crafted from SS321 stainless steel for excellent durability and corrosion resistance in exhaust systems. The 1D radius means the bend is tight, making it useful for fitting exhaust sections into tight spaces without kinking.

This elbow features a 16-gauge wall thickness, which is .065 inches, offering a good balance between strength and weldability for custom exhaust projects. Because it's a mandrel bend, the tubing maintains its full diameter throughout the curve, ensuring unrestricted exhaust flow. This piece is designed for fabrication, meaning it doesn't have any extra legs or mounting points, giving you a clean starting point for building custom exhaust pipes, headers, or intercooler piping.
