5in (127mm) O.D. 90 degr ee Mandrel Bend

The 5-inch O.D. 90 degree mandrel bend from Vibrant Performance is a precision exhaust and intake tube component engineered for custom automotive fabrication and modification. Whether you're building a high-performance exhaust system, turbo intake piping, or intercooler ducting, this mandrel bend maintains consistent inside diameter throughout the curve, preventing the kinking and flow restriction that plague welded or hot-bent tubing. Designed for serious fabricators and enthusiasts who demand professional results, this component is essential for optimizing airflow in forced-induction setups, naturally aspirated engine builds, and custom cooling systems.

Mandrel bending technology uses a flexible core inserted into the tube during bending, which supports the inner wall and prevents collapse. The 5-inch outer diameter with a true 90-degree angle allows seamless transitions in tight engine bay applications while maintaining superior flow characteristics compared to conventional bends. The precision bend radius and consistent wall thickness throughout ensure minimal turbulence and maximum efficiency in both exhaust gas scavenging and intake charge delivery. This Vibrant Performance bend is manufactured to OEM quality standards, making it ideal for bolt-on modifications or complete custom fabrication where durability and performance are non-negotiable.

Fabricators, tuners, and weekend warriors building everything from street machines to track-focused builds rely on mandrel bends to maximize horsepower gains and thermal efficiency. This 127mm component integrates seamlessly into modular exhaust systems, intercooler piping, and intake manifold work where sharp 90-degree directional changes are required. Installation typically involves MIG or TIG welding into your custom assembly, and the smooth inner surface eliminates the need for post-bend deburring or flow simulation. Weighing 9.83 lbs and measuring 14 x 5 x 26 inches, it's substantial enough for serious applications yet maneuverable enough for precise fitment in compact engine bays.
