What makes a 'mandrel bend' better for exhaust systems?

A mandrel bend is formed using a flexible metal 'mandrel' inside the tube. This process prevents the tube from collapsing or kinking during the bend, ensuring a smooth, consistent inner diameter. This helps maintain optimal exhaust flow compared to crush bends.

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

304 stainless steel is chosen for exhaust components because it offers excellent resistance to corrosion and heat. This helps the tubing last longer, especially in harsh conditions where it's exposed to moisture and exhaust gases.

Does this part come with any hardware for installation?

This product is a single piece of 3 1/2 inch, 45-degree mandrel bent tubing. It does not include any additional hardware for installation; you will need to source appropriate clamps, welds, or other connection methods for your custom fabrication project.

Product Details

Stainless Works is known for making well-built exhaust components, and this 3 1/2-inch, 45-degree mandrel bend is a prime example. If you're building a custom exhaust system or modifying an existing one, having smooth, consistent bends is key to good flow. This piece is designed to help you achieve that.

It's made from 304 stainless steel, which is a solid choice for exhaust work because it holds up well against corrosion. The tubing has a .065 wall thickness and is CNC mandrel bent. That means the bend is formed without crushing or kinking the tube, keeping the inside diameter consistent and the airflow smooth. Each leg on this bend is at least 6 inches long, giving you plenty of material to work with when connecting it to other pipes.

This is a universal part, so it's great for all sorts of custom fabrication projects. It comes with a lifetime warranty and is proudly made in the USA.
