Vibrant 13103 3.5in T304 Stainless 45-Degree Mandrel Bend

Vehicle Fitment

• Universal - not vehicle-specific; used for building custom exhaust systems, headers, and downpipes

Fitment Notes

• Welding required for installation into a custom exhaust or header assembly.

Features

• Mandrel-bent for a smooth, consistent internal diameter with no crimping or wall collapse
• T304 stainless steel resists rust, heat, and corrosion far better than mild steel
• Dimensionally consistent tubing requires minimal prep before welding
• Capable of withstanding acidic, high-heat, and corrosive exhaust gas conditions
• Ideal for custom exhaust systems, headers, and downpipe fabrication
• Backed by a 5-year limited warranty

• Leg Length (from tangent): 6"
• Wall Thickness: 16 Gauge (0.065")
• Material: T304 Stainless Steel

Included Components

• 1x 3.5" 45-Degree Mandrel Bend

Product Description

Building a custom exhaust or header system means piecing together bends that route cleanly around chassis components without choking flow - and a crimped or cheaply-formed bend can quietly rob power even when the diameter looks right. The Vibrant 13103 is a true mandrel-bent 45° section, holding a consistent 3.5" internal diameter through the entire bend so exhaust flow stays smooth rather than restricted at the turn.

T304 stainless steel construction stands up to the heat and corrosive byproducts of exhaust gas far longer than mild steel, and the tubing's dimensional consistency means less prep work before welding it into a custom system. It's a standard building block for fabricators piecing together headers, downpipes, or full custom exhaust runs where precise, repeatable bends matter.
