What makes 304 stainless steel a good choice for exhaust tubing?

304 stainless steel is a popular choice for exhaust systems because it offers strong resistance to corrosion and heat. This helps ensure the longevity of your custom fabrication, even in harsh operating conditions.

What does 'CNC mandrel bent' mean for this exhaust tube?

CNC mandrel bending means the tube is bent using a machine that supports the inside of the tube with a mandrel. This process prevents the tube from collapsing or kinking during the bend, ensuring a smooth, consistent inner diameter for optimal exhaust flow.

What is included with this 180-degree bend?

This product is a single 4-inch, 180-degree J-bend made from 304 stainless steel. It includes a minimum of a 6-inch leg and a 12-inch leg, ready for cutting and welding into your custom exhaust project.
