Product Description

The Vibrant Performance 13134 4" 15° Mandrel Stainless Steel Exhaust Bend is a universal fabrication component designed for custom exhaust, intake, or intercooler plumbing systems where a slight directional change is needed. The mandrel-bent design ensures the internal diameter stays consistent through the bend, which helps maintain smooth flow and minimizes pressure loss compared to traditional crush bends - an essential factor in high-flow setups. The raw stainless finish allows easy welding and integration into bespoke piping systems.

Constructed from durable 304 stainless steel with a 16-gauge wall thickness, this 15° bend is suited for performance exhaust headers, downpipes, turbo plumbing, and intercooler applications. Its universal design means it isn't tied to any specific vehicle year, make, or model, giving fabricators and builders flexibility to use it across a wide range of custom projects where quality, strength, and smooth flow are priorities.
