4.5in OD T6061 Aluminum Straight Tube - 18in lon

The 4.5in OD T6061 Aluminum Straight Tube – 18in long from Vibrant Performance is a precision-engineered component designed for builders and fabricators working on custom exhaust systems, intercooler piping, intake manifolds, and other high-temperature applications. Whether you're constructing a turbo setup, designing a custom cooling circuit, or assembling modular exhaust tubing, this aluminum tube provides a reliable foundation that meets professional-grade standards. Built to spec for automotive professionals who demand accuracy and repeatability in their modifications.

Manufactured from T6061 aluminum alloy, this straight tube delivers a balance of strength, machinability, and thermal performance essential for engine bay work. The 4.5-inch outer diameter (OD) provides a large-diameter flow path ideal for boosted applications and intercooler core piping where restriction minimizes turbo lag and heat soak. At 18 inches in length, the tube offers sufficient material for cutting, welding, and forming without excessive waste, while the light 2.76 lb weight keeps overall system mass down—critical for performance-oriented builds. T6061's excellent weldability and corrosion resistance make it suitable for both pressurized cooling circuits and exhaust routing where temperatures remain moderate.

This tube is ideal for turbo and supercharger installers, custom fabricators, and DIY enthusiasts building one-off intake or cooling systems on domestic and import platforms. The straight profile allows for clean bends and joints using standard tube benders and welding techniques, making it compatible with both TIG and MIG welding processes. Vibrant Performance's precision manufacturing ensures consistent wall thickness and dimensional accuracy, reducing fitment issues during assembly. Use in conjunction with appropriate aluminum fittings, adapters, and flanges to create leak-free, OEM-quality results in your custom plumbing or exhaust design.
