What is SS321 stainless steel and why is it used for exhaust tubing?

SS321 is a type of stainless steel that includes titanium. This addition makes it more resistant to high temperatures and corrosion, especially in exhaust systems where components are exposed to extreme heat and exhaust gases.

What kind of projects is this tubing best suited for?

This tubing is ideal for custom exhaust fabrication, including building headers, mid-pipes, or custom muffler sections. Its specific diameter and material make it a good choice for performance-oriented builds.

Is this tubing easy to work with for custom builds?

Yes, the 16-gauge wall thickness and the nature of stainless steel make this tubing suitable for bending and welding, allowing for clean fabrication of custom exhaust components.

About this part

Product Details

Crafted from SS321 stainless steel with a 16-gauge (.065 inch) wall thickness, this 48-inch straight tube offers a solid foundation for custom exhaust projects. The SS321 alloy is known for its enhanced high-temperature strength and resistance to sensitization, making it a reliable choice for exhaust systems that see a lot of heat. Its 1.88-inch outer diameter is a common size for many performance exhaust applications, allowing for good flow without being excessively large.

This tubing is well-suited for fabricating custom exhaust headers, mid-pipes, or muffler sections where precise fitment and durability are important. The consistent wall thickness ensures ease of bending and welding, helping to achieve clean, professional-looking results on your build. Whether you're replacing a damaged section or building a unique exhaust system from scratch, this tubing provides the material integrity needed for a long-lasting installation.
