180 Degree Aluminum Bend 3.5in O.D. Polished

The 180 Degree Aluminum Bend 3.5in O.D. Polished by VIBRANT PERFORMANCE is a precision mandrel-bent exhaust pipe component engineered for custom intake, exhaust, and intercooler piping systems. This tight 180-degree U-bend is essential for builders and fabricators who demand smooth airflow paths without kinks, turbulence, or restrictive angles. Whether you're designing a high-performance turbo setup, upgrading intercooler plumbing, or routing custom exhaust tubing on a street or track build, this aluminum bend eliminates the need for welding multiple 45-degree or 90-degree segments while maintaining structural integrity and aerodynamic efficiency.

Constructed from premium aluminum alloy, this component features a polished finish that resists oxidation and provides a professional appearance in engine bays exposed to heat and moisture. The 3.5-inch outside diameter accommodates larger-volume airflow applications common in forced-induction and high-displacement engine builds. VIBRANT PERFORMANCE's mandrel-bend process ensures the interior radius maintains consistent wall thickness throughout the bend, preventing collapse under boost pressure and reducing turbulent flow characteristics that diminish volumetric efficiency. The polished surface finish not only looks refined but also simplifies cleaning and inspection during maintenance while the lightweight aluminum construction helps minimize overall system weight compared to steel alternatives.

This 180-degree bend suits builders working on turbo intercooler pipes, custom intake manifold runners, or exhaust header fabrication where smooth transitions and tight packaging are critical. The 3.5-inch diameter works well with moderate-to-high-flow applications, making it ideal for LS swaps, small-block modifications, and late-model performance platforms. Installation requires TIG welding or the use of mandrel bend adapters and couplings compatible with 3.5-inch tubing. Verify your piping wall thickness and material compatibility before ordering, as this bend pairs best with 0.049-inch to 0.065-inch wall aluminum or steel tubing in matching 3.5-inch O.D. dimensions.
