Vibrant 13764 321 SS Straight Tubing 2 in. OD 18-Gauge 1 Meter Universal

Vehicle Fitment

• Universal - No vehicle-specific fitment. Suitable for any custom exhaust, downpipe, turbo piping, or forced induction fabrication application using 2 in. O.D. tubing.

Fitment Notes

• This is a universal fabrication component. Installer is responsible for confirming diameter compatibility with existing tubing before cutting and welding.
• 321 stainless steel is specifically recommended for high-temperature forced induction applications where 304 SS may be insufficient.

Features

• 321 stainless steel outperforms 304 SS at sustained elevated temperatures of 800°F to 1500°F (427°C to 816°C)
• Superior corrosion resistance and better tensile stress and stress fracture resistance versus 304 stainless
• 18-gauge (0.049 in.) wall thickness offers a balance of strength and reduced weight for performance builds
• Dimensionally consistent construction ensures accurate, weld-ready fitment along the full 1 meter length
• Ideal for downpipes, turbo outlets, wastegate dump tubes, and other high-heat forced induction applications
• Raw finish is weld-ready for TIG or MIG with standard stainless or 321-compatible filler wire
• Compatible with Vibrant 321 SS mandrel bends available in the same 2 in. O.D. size
• Part of Vibrant's full 321 SS tubing and bend program for complete forced induction builds

Product Description

The Vibrant 13764 is a 1 meter length of 18-gauge 321 stainless steel straight tubing in 2 in. O.D. Unlike standard 304 stainless, 321 SS incorporates titanium stabilization that allows it to maintain structural integrity and corrosion resistance at sustained temperatures between 800°F and 1500°F - the range common in turbocharger downpipes, manifolds, and wastegate dump tubes. This makes it the preferred material for forced induction builds where exhaust gases remain at extreme temperatures for extended periods.

At 18-gauge wall thickness, the 13764 is slightly thinner than the 16-gauge 304 SS equivalent, offering a modest weight advantage while still providing the rigidity needed for performance exhaust work. The raw finish is weld-ready and pairs directly with Vibrant's 321 SS mandrel bend lineup in the same 2 in. O.D. for builders looking to complete a full high-temperature fabrication system from a single material family.
