What does '1.5D' mean for the bend radius?

The '1.5D' refers to the bend radius, which is 1.5 times the diameter of the tubing. For this 1.625-inch tube, the center of the bend is 1.5 times that measurement away from the tube's center line. This creates a smoother, wider turn compared to tighter bends.

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

A mandrel bend uses a flexible internal support (the mandrel) to maintain the tube's shape and diameter during the bending process. This prevents the tube from kinking or collapsing, ensuring unrestricted exhaust flow and preventing turbulence that can hurt performance.

What is the advantage of stainless steel for exhaust tubing?

Stainless steel is chosen for exhaust components because it offers good resistance to rust and corrosion, which are common issues with exhaust systems exposed to heat, moisture, and road salt. This helps the tubing last longer.

About this part

Product Details

Stainless Bros is known for providing a wide range of stainless steel exhaust components. This particular piece is a 1.625-inch diameter, 90-degree bend with a 1.5D (1.5 times the diameter) radius, designed for custom exhaust fabrication. It's a mandrel bend, meaning the tube's diameter stays consistent through the bend, which is crucial for maintaining smooth exhaust flow and preventing restrictions.

This bend is made from stainless steel, which offers good resistance to corrosion, especially important for exhaust systems that deal with heat and moisture. The 'no leg' design means it doesn't have any straight sections extending from the bend itself, making it ideal for tight fitment situations where you need to connect directly into another component or weld point. It's a straightforward piece for builders looking to create custom exhaust routing, headers, or intake piping.
