Product Description

The Vibrant Performance 13104 4" 45° Mandrel Stainless Steel Exhaust Bend is a universal fabrication component designed for custom exhaust, intake, or intercooler plumbing systems. Its mandrel-bent geometry keeps the internal diameter consistent through the curve, minimizing flow restriction and turbulence - a key advantage in high-flow applications where maintaining performance is critical.

Constructed from durable 304 stainless steel with thick walls for strength and long service life, the 13104 bend is ready for welding into bespoke exhaust systems, turbo plumbing, downpipes, and other performance setups. With equal ~6" leg lengths and a ~6" centerline radius, this bend offers flexibility in tight routing situations while providing reliable performance in street, track, or high-boost builds. Its universal design means it's suitable for a wide range of custom automotive projects, not tied to specific vehicles.
