What does 'mandrel bend' mean for my exhaust?

A mandrel bend uses a flexible internal support (the mandrel) to maintain the tube's original diameter through the curve. This prevents the tube from collapsing or kinking, which helps keep exhaust gases flowing smoothly.

What is the '1.5D' measurement?

The '1.5D' refers to the centerline radius of the bend, measured in multiples of the tube's diameter. So, a 1.5D radius means the center of the bend's curve is 1.5 times the tube's diameter away from the tube's center.

What is this tubing typically used for?

This type of tubing is commonly used by fabricators to build custom exhaust systems, headers, or intake piping where specific bends and consistent diameter are needed for optimal performance and fit.

About this part

Product Details

If you're fabricating a custom exhaust system, getting the bends just right is key to a clean install and good flow. This piece of tubing from Stainless Bros is a 180-degree bend, meaning it makes a full U-turn, perfect for routing pipes back on themselves or creating tight header collectors.

It's made from stainless steel, which holds up well against exhaust heat and corrosion, and it's mandrel-bent. That means the tube's diameter stays consistent through the bend, unlike crush bends that can restrict flow. This particular bend has a 1.88-inch outer diameter, a 1.5D (1.5 times the diameter) centerline radius, and two 6-inch legs extending from the bend itself. This makes it a versatile piece for many custom exhaust projects.
