What does 'mandrel bend' mean for an exhaust pipe?

A mandrel bend uses a flexible internal support (the mandrel) to keep the pipe from collapsing or kinking during the bending process. This ensures the pipe's diameter remains consistent throughout the curve, which is crucial for optimal exhaust gas flow.

What is the '1.5D radius' on this elbow?

The '1.5D radius' refers to the tightness of the bend. 'D' represents the diameter of the tubing (2.25 inches in this case). So, a 1.5D radius means the center of the bend is 1.5 times the tubing's diameter away from the center of the tube itself. This indicates a relatively tight, but still smooth, curve.

What material is this exhaust elbow made from?

This exhaust elbow is made from stainless steel. Stainless steel is commonly used in exhaust systems because it holds up well against heat and corrosion from exhaust gases and road elements.

About this part

Product Details

If you're fabricating a custom exhaust system, getting the bends right is key to smooth flow and a clean look. This 90-degree elbow from Stainless Bros is made from stainless steel and features a mandrel bend, meaning the tube's diameter stays consistent through the curve. This helps prevent turbulence and keeps exhaust gases flowing efficiently, which is important for performance and sound.

The 1.5D radius on this bend means the center of the curve is 1.5 times the diameter of the tubing away from the tube's center. This tighter radius is useful when you need to make a sharp turn in a limited space, like fitting an exhaust system around frame rails or other undercarriage components. Each leg measures 2 inches long, giving you some room to work with when connecting it to other exhaust sections.
