What is SS321 stainless steel and why is it good for exhaust?

SS321 stainless steel is an alloy that includes titanium. This addition helps stabilize the steel against carbide precipitation, which can occur at high temperatures. This makes it more resistant to corrosion and cracking in the demanding environment of an exhaust system compared to standard stainless steel.

What kind of fabrication work is this tubing best suited for?

This tubing is well-suited for a variety of custom exhaust fabrication tasks. This includes building custom exhaust headers, fabricating cat-back exhaust systems, or repairing sections of existing exhaust pipes and mufflers.

Does this tubing come with any hardware or connectors?

This product is for the tubing only. Any necessary hardware, clamps, hangers, or additional exhaust components would need to be purchased separately.

About this part

Product Details

If you're building a custom exhaust system or repairing an existing one, having the right tubing on hand is key. This 48-inch length of 2-inch diameter tubing from Stainless Bros is made from SS321 stainless steel, a well-known material for its strength and resistance to corrosion, especially at high temperatures. The 16-gauge (0.065-inch) wall thickness offers a good balance between durability and ease of fabrication, making it suitable for welding and bending without being overly heavy.

SS321 stainless steel is a popular choice for exhaust components because it contains titanium, which helps prevent carbide precipitation during welding and high-heat exposure. This means it holds up better over time in the harsh environment of an exhaust system compared to standard 304 stainless steel. Whether you're fabricating headers, a custom cat-back, or repairing a muffler section, this tubing gives you a solid foundation for a long-lasting exhaust build.
