Vibrant 13780 321 SS Straight Tubing 1.5 in. OD 16-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 1.5 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 at sustained elevated temperatures.

Features

• 321 stainless steel outperforms 304 SS at sustained 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
• 16-gauge (0.065 in.) wall thickness provides added structural rigidity compared to the thinner 18-gauge 321 SS offerings
• Dimensionally consistent construction ensures accurate, weld-ready fitment along the full 1 meter length
• Ideal for downpipes, turbo outlets, wastegate dump tubes, and other sustained 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 matching 1.5 in. O.D. sizing
• Part of Vibrant's complete 321 SS tubing and bend program for high-temperature builds

Product Description

The Vibrant 13780 is a 1 meter length of 16-gauge 321 stainless steel straight tubing in 1.5 in. O.D. The 321 alloy incorporates titanium stabilization that allows it to maintain structural integrity and resist oxidation at sustained temperatures between 800°F and 1500°F - significantly beyond the practical limit of standard 304 SS. This makes it the preferred choice for smaller-diameter high-heat applications including wastegate dump pipes, turbo outlet sections, header primaries, and other components that see prolonged extreme temperatures in forced induction builds.

At 16-gauge wall thickness, the 13780 is heavier-walled than the 18-gauge variants in the Vibrant 321 SS lineup, offering added rigidity for installations subject to vibration or mechanical stress. The raw finish arrives weld-ready and pairs directly with Vibrant's 321 SS mandrel bend lineup in the same 1.5 in. O.D. for builders looking to complete a full high-temperature fabrication system from a single consistent material.
