Straight Tubing 1.75in OD x 39.375in Long

The Straight Tubing 1.75in OD x 39.375in Long from Vibrant Performance is a precision-engineered exhaust and intake manifold component designed for custom fabrication and system modifications. This straight section serves as a foundational building block for builders constructing custom headers, intake runners, or air-to-air intercooler piping on performance vehicles. Whether you're designing a show car exhaust system, turbocharging a non-turbocharged platform, or routing charge-air cooling lines, this tubing provides the structural integrity and dimensional consistency required for professional-grade fabrication.

Constructed from mandrel-bent or seamless tubing stock, the 1.75-inch outer diameter balances flow capacity with compact packaging—ideal for mid-range engine displacement and moderate boost applications. The 39.375-inch length provides ample material for cutting and welding custom runners without excessive waste, while the tight dimensional tolerance ensures precise fitment when combined with bends, elbows, and flanges from Vibrant's modular tubing system. At just 2.35 pounds, this lightweight section minimizes unsprung mass while maintaining the wall thickness necessary for pressure containment and vibration resistance in high-temperature exhaust environments or pressurized intake circuits.

Experienced fabricators, turbo kit manufacturers, and serious engine builders rely on Vibrant Performance straight tubing for one-off custom work and small-batch production runs. This component pairs seamlessly with Vibrant's flanges, bends, couplers, and clamps to create complete exhaust and charge-air systems tailored to any engine bay layout. Installation requires basic welding and grinding skills; use proper jigs and thermal protection during cutting and joining. Suitable for naturally aspirated, supercharged, and turbocharged applications across small-block and mid-size engines.
