Shop 409 stainless steel mandrel bends from 1.5" to 5" in diameter for automotive exhaust systems, custom exhaust fabrication, performance applications and exhaust repairs from Lyell’s Stainless Exhaust. Our selection of 409 stainless steel exhaust bends includes multiple diameters, bend angles and configurations, including 45°, 60°, 90° and 180° mandrel bends, J-bends and offset bends for building and routing custom exhaust systems. Popular exhaust tubing sizes include 1.5", 1.75", 2", 2.25", 2.5", 3", 4" and 5", providing options for cars, trucks, performance vehicles and custom exhaust projects. 409 stainless steel is widely used for automotive exhaust applications because it offers an excellent combination of heat resistance, durability, corrosion resistance and weldability while remaining a cost-effective stainless steel option for exhaust fabrication. The mandrel bending process helps maintain a smooth and consistent tubing diameter throughout the bend, reducing restriction and allowing for efficient exhaust flow compared with bends that significantly deform or narrow the tubing. Whether you're building a complete custom exhaust system, replacing an exhaust section, fabricating a downpipe or creating custom exhaust routing, Lyell’s Stainless Exhaust supplies 409 stainless steel mandrel bends and exhaust tubing to customers across Canada and the United States, including professional exhaust shops, automotive repair facilities, performance shops, custom fabricators, welders and DIY builders.
