Vibrant 13133 304 SS 15-Degree Mandrel Bend Tubing 3.5 in. OD Universal

Vehicle Fitment

• Universal - No vehicle-specific fitment. Suitable for any custom exhaust, intake, turbo, or intercooler fabrication application.

Fitment Notes

• This is a universal fabrication component. Installer is responsible for confirming tube diameter compatibility with existing piping before installation.
• Professional welding is recommended for proper installation.

Features

• Constructed from T304 stainless steel for superior corrosion and heat resistance
• Mandrel-bent process preserves full inner diameter with no tube collapse or flow restriction
• 15-degree bend angle for subtle directional changes in tight fabrication spaces
• 16-gauge (0.065 in.) wall thickness provides strength without added bulk
• Raw finish accepts MIG, TIG, or stainless welding without surface prep issues
• Consistent roundness and concentricity for clean, gap-free welds
• Compatible with Vibrant couplers, clamps, and V-band flanges
• Suitable for exhaust, downpipe, intercooler, and induction piping builds

Product Description

The Vibrant 13133 is a 15-degree T304 stainless steel mandrel bend designed for custom exhaust, downpipe, intercooler, and induction fabrication. The mandrel-bending process maintains full bore flow throughout the curve, preventing the restrictions and oval distortion common with press-bent tubing. With a 3.5 in. outer diameter, 5.5 in. centerline radius, and equal 5 in. leg lengths on both ends, this piece integrates cleanly into tight routing scenarios where a minor directional change is needed without sacrificing flow.

Built from 16-gauge T304 stainless steel, this bend delivers long-term durability against heat, moisture, and road debris. The raw finish welds easily to matching stainless tubing and is compatible with Vibrant's full line of connectors, clamps, and flanges. Whether you're building a one-off turbo kit, fabricating a custom cat-back, or routing intercooler piping, the 13133 offers the precision and consistency needed for professional-quality results.
