Stainless Bros 48in Length 2.25in SS321 Straight Tube - 16GA/.065in Wall

If you're fabricating a custom exhaust system, having the right tubing is key. This 48-inch length of straight tubing from Stainless Bros is made from SS321 stainless steel, a popular choice for exhaust components because it holds up well to high temperatures and corrosive exhaust gases. The 16-gauge wall thickness, which is about 0.065 inches, offers a good balance of strength and workability for most exhaust builds.

This particular piece is 2.25 inches in diameter, a common size for many performance and custom exhaust applications. SS321 stainless steel is known for its added titanium content, which helps prevent carbide precipitation at high temperatures, making it a solid option for exhaust manifolds, downpipes, and mid-pipes where heat is a major factor. Its corrosion resistance means it will last longer than standard aluminized steel or mild steel tubing in harsh conditions.
