What does 'mandrel bend' mean for my exhaust project?

A mandrel bend is formed using a flexible mandrel inside the tubing. This process prevents the tube from collapsing or kinking during the bend, ensuring a smooth, consistent inner diameter for better exhaust flow.

What is the '1.5D' designation on this tubing?

The '1.5D' refers to the bend radius in relation to the tube's diameter. In this case, the centerline radius of the bend is 1.5 times the tube's outer diameter, indicating a fairly tight, but still smooth, turn.

What are the leg lengths on this bend?

Each straight section, or leg, extending from the center of the bend measures 6 inches long. This gives you ample room for connecting to other exhaust components.

About this part

Product Details

When you're building a custom exhaust system, getting the bends just right is key. This piece from Stainless Bros is a 180-degree mandrel bend, meaning it's formed under pressure to keep the tube from collapsing, ensuring consistent flow. It's made from stainless steel, which holds up well against exhaust heat and moisture.

This particular bend has a 2.25-inch outer diameter and a 6-inch leg on each side of the bend. The 1.5D designation refers to the bend radius relative to the tube diameter, giving you a fairly tight turn for its size. It's a well-built piece that makes it easier to route your exhaust tubing cleanly around frame rails or other undercarriage components.
