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 consistent inner diameter and smooth airflow, which is vital for exhaust system performance.

What does '1.5D / 3.75in CLR' mean for this bend?

The '1.5D' refers to the bend radius being 1.5 times the tube's diameter. For a 2.50-inch tube, this results in a centerline radius (CLR) of 3.75 inches. This measurement helps determine how much space the bend will occupy.

What kind of projects is this bend leg typically used for?

This 90-degree bend leg is commonly used in custom exhaust fabrication, such as building headers, downpipes, or full cat-back systems. It's also useful for intake piping or other custom tubing applications where a tight, smooth bend is required.

About this part

Product Details

This 90-degree mandrel bend leg from Stainless Bros features a 2.50-inch outer diameter and a 1.5D (1.5 times the diameter) bend radius, resulting in a 3.75-inch centerline radius. Mandrel bending ensures the tube maintains its shape and diameter throughout the bend, preventing kinks or flat spots that can restrict exhaust flow. This is crucial for custom exhaust systems where smooth flow is important for performance and sound.

Crafted from durable steel, this bend leg is designed for fabrication projects where precise angles and consistent tubing diameter are needed. Its 90-degree angle makes it suitable for routing exhaust pipes around obstacles or transitioning between sections in a custom build. Whether you're building a unique exhaust system for a show car or optimizing performance on a track vehicle, this component offers a clean, professional-looking bend.
