What makes mandrel bends better for custom exhaust fabrication?

Mandrel bending uses a support tool inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring a smooth, consistent inner diameter. This is important for maintaining optimal exhaust flow and preventing restrictions.

Why is 304 stainless steel a good material for exhaust components?

304 stainless steel is chosen for its excellent resistance to corrosion and rust. This makes it a durable material for exhaust systems, which are exposed to moisture, heat, and road debris. It holds up well over time compared to other types of steel.

Does this bend come with any hardware or clamps?

This product is a single 3-1/2 inch, 90-degree mandrel bend. It does not include any additional hardware, clamps, or welding supplies. You will need to source those separately for your custom fabrication project.

Product Details

This is a 3-1/2 inch, 90-degree mandrel bend from Stainless Works, designed for custom exhaust fabrication. It’s made from 304 stainless steel, which is known for resisting rust and corrosion, making it a solid choice for exhaust work. The .065 wall thickness is common for exhaust tubing, and the CNC mandrel bending ensures smooth, wrinkle-free bends that help maintain good exhaust flow. Each leg on the bend is a minimum of 6 inches long, giving you plenty of material to work with when connecting it to your exhaust system.

Using mandrel bends like this one is important for custom exhaust builds because it prevents the tube from collapsing or kinking during the bending process. This maintains the internal diameter of the pipe, which is crucial for keeping exhaust gases flowing efficiently. The 304 stainless steel construction means it will hold up well over time, even in harsh conditions. Stainless Works backs these bends with a lifetime warranty, and they are proudly made in the USA.
