Pipemaster 1-3/4in OD Tube

The Pipemaster 1-3/4in OD Tube is an essential component for custom exhaust systems, intake manifold fabrication, and header construction in automotive performance builds. Whether you're designing a turbo intake manifold, custom exhaust routing, or structural tubing work, this precisely dimensioned tube provides the foundation for quality metalwork. Mechanics and fabricators rely on standardized OD tubing like this to ensure consistent fit, weld quality, and long-term durability in high-temperature and high-vibration environments.

The 1-3/4 inch outer diameter specification makes this tube ideal for mid-range applications where flow characteristics and wall thickness balance durability with weight savings. This size is commonly selected for V6 and small-displacement V8 exhaust manifolds, as well as intake plenum fabrication where internal runner diameter and external clearance must be carefully managed. The tube's geometry—with its 10.45-inch length and compact 5-inch width profile—allows for efficient bending, notching, and welding without excessive material waste, making it a cost-effective choice for both one-off custom builds and production fabrication shops.

Fabricators working on LS-engine swaps, 4-cylinder turbo projects, and classic car restorations will find this tubing size fits seamlessly into manifold design calculations and header flanging workflows. Its lightweight construction at 0.83 lbs per piece minimizes unsprung mass while maintaining the structural integrity needed for engine bay temperatures and vibration loads. Installation requires standard metal fabrication equipment—a quality tube notcher, TIG or MIG welder, and proper jigs for alignment—and pairs well with mandrel bending for smooth flow paths without turbulence-inducing kinks.
