2-1/4in x .065 Tubing 4 Ft

The 2-1/4in x .065 Tubing 4 Ft from Stainless Works is a premium exhaust and chassis fabrication component engineered for serious automotive builders, welders, and performance mechanics. This 48-inch straight tubing section serves as the foundation for custom exhaust systems, roll cages, frame reinforcements, and mid-pipe assemblies on street rods, race cars, and heavily modified vehicles. Whether you're designing a high-flow exhaust that maximizes scavenging efficiency or constructing structural bracing that increases chassis rigidity, this tubing delivers the dimensional precision and material quality that separates professional builds from amateur projects.

Constructed from high-quality stainless steel, the 2-1/4-inch outer diameter with .065-inch wall thickness balances strength and weight—critical for both structural integrity and performance tuning. The .065 wall provides robust resistance to vibration cracking and thermal cycling while remaining light enough for suspension-sensitive builds. Stainless Works' material specification resists corrosion from exhaust heat and moisture exposure, ensuring longevity in demanding under-hood environments where mild steel would rust through in seasons. The four-foot length allows customization for mid-pipe sections, downpipes, and chassis bracework without excessive welding joints, reducing potential failure points in high-temperature or high-stress applications.

This tubing is ideal for builders fabricating custom exhaust systems, turbo piping, intercooler plumbing, and structural reinforcements on engine-swapped or turbocharged platforms. The 48-inch straight section can be cut, mandrel-bent, or welded to specification without sacrificing structural properties. Installation requires standard TIG or MIG welding equipment and basic metal fabrication skills; stainless material demands proper shielding gas (argon) to prevent oxidation at the weld bead. Mechanics and fabricators working with LS swaps, 5.0 Coyote conversions, and forced-induction builds rely on Stainless Works tubing for repeatability and performance consistency across multiple builds.
