Straight Tubing 1.50in OD x 39.375in Long

The Straight Tubing 1.50in OD x 39.375in Long from Vibrant Performance is a precision-engineered exhaust and intake piping component designed for builders who demand reliability in custom fabrication projects. Whether you're constructing a high-performance exhaust system, intake manifold runner, or intercooler piping network, this straight tubing serves as a foundational building block for serious automotive modifications. Mechanics and enthusiasts rely on this component because it delivers consistent wall thickness and concentricity—critical factors when you're aligning turbo kits, supercharger plumbing, or custom headers where tolerances matter.

Manufactured to OEM standards, this 1.50-inch outer diameter tubing is commonly used in mid-range turbo applications and small-displacement engine builds where space constraints demand compact runner geometry. The 39.375-inch length provides enough material for multi-runner layouts or extended intake charge paths without requiring secondary welded joints in critical flow areas. At just 1.98 pounds, the tubing weight remains minimal—essential when optimizing engine bay packaging and keeping rotating assembly mass low for naturally aspirated and forced-induction platforms alike. The mandrel-bent construction (typical for Vibrant Performance products) ensures consistent inner diameter and eliminates collapse points that restrict airflow or create turbulence.

Builders working on LS engine swaps, four-cylinder turbo projects, and small-block V8 conversions will find this straight tubing indispensable for custom exhaust primaries, cold-side intercooler piping, and intake runner fabrication. It pairs seamlessly with Vibrant Performance's bend kits and flanges, allowing you to prototype complex runner angles before committing to full bends. Installation requires basic TIG welding skills and proper fixture setup—plan for tube notching or stepped transitions if joining to larger diameter piping. This product is ideal for one-off custom builds where production bent tubes don't match your unique runner layout or mounting geometry.
