What is a mandrel bend and why is it important for exhaust systems?

A mandrel bend is created using a flexible mandrel inside the tube during the bending process. This prevents the tube from collapsing or kinking, ensuring the inner diameter remains consistent. For exhaust systems, this means better flow and less restriction compared to crush bends.

What does 1.5D / 4.125in CLR mean for this tube?

The '1.5D' refers to the bend radius being 1.5 times the tube's diameter. The '4.125in CLR' specifies the actual centerline radius of the bend in inches. This indicates a relatively gentle bend, which is good for exhaust flow.

What material is this exhaust tubing made from?

This exhaust tubing is made from steel. While the specific type of steel isn't detailed, it's intended for fabrication and custom exhaust applications.

About this part

Product Details

What you get with this order is a single 2.75-inch diameter, 90-degree mandrel bend tube from Stainless Bros. It features a 1.5D (1.5 times the diameter) bend radius, which translates to a 4.125-inch centerline radius. Each leg of the bend measures 6.5 inches long, making it a useful component for custom exhaust system fabrication.

This piece is made from steel tubing and is bent using a mandrel process. Mandrel bending ensures that the tube maintains its diameter and shape throughout the bend, preventing flat spots or kinks that could restrict exhaust flow. This is important for any custom exhaust build where smooth flow is a priority. The 90-degree angle and specific leg lengths offer flexibility for routing exhaust gases around obstacles or connecting different sections of pipe.
