What is a mandrel bend and why is it important for exhaust systems?

A mandrel bend is created using a flexible mandrel inside the tubing during the bending process. This prevents the tube from collapsing or kinking, ensuring a smooth, consistent inner diameter. For exhaust systems, this means better flow and performance compared to crush bends.

What is the advantage of 304 stainless steel for exhaust tubing?

304 stainless steel is a well-known material for exhaust components because it offers excellent resistance to corrosion and heat. This helps the tubing last longer, especially in harsh undercar environments where it's exposed to moisture and exhaust gases.

What does the .049 wall thickness mean for this exhaust tube?

The .049 wall thickness indicates the thickness of the steel used for the tubing. This is a common and practical thickness for custom exhaust fabrication, offering a good balance between durability and ease of welding or manipulation.

About this part

Product Details

This 3-inch, 180-degree J-bend from Stainless Works is CNC mandrel bent, meaning it maintains its shape through the bend for smooth, unrestricted exhaust flow. It’s constructed from 304 stainless steel with a .049 wall thickness, which offers good corrosion resistance and is well-suited for custom exhaust projects. The bend comes with a minimum 6-inch leg and a 12-inch leg, giving you plenty of material to work with during fabrication.

Using mandrel bends like these is crucial for custom exhaust work because they prevent the tube from collapsing or kinking, which can happen with standard pipe bending. This ensures that exhaust gases can exit the engine efficiently, helping to maintain performance. The 304 stainless steel construction is a solid choice for exhaust components, offering durability and resistance to rust and heat.
