Exhaust Tubing - 4.000 16 Gauge - 5ft. Long

The Exhaust Tubing - 4.000 16 Gauge - 5ft. Long from PATRIOT EXHAUST is a professional-grade pipe section designed for custom exhaust system fabrication and modification work. Whether you're building a complete cat-back system, extending an existing exhaust line, or designing a performance header, this straight tubing section serves as the foundational building block for serious exhaust work. This product is ideal for mechanics and fabricators who demand precision materials that integrate seamlessly with OEM or aftermarket exhaust components.

Constructed from 16-gauge steel with a 4.000-inch outer diameter, this tubing delivers the structural integrity and thermal resistance required for high-temperature exhaust gas flow. The 16-gauge thickness provides optimal balance between durability and workability—heavy enough to withstand pressure cycles and vibration without excessive weight, yet manageable for cutting, bending, and welding during installation. The 5-foot length provides sufficient material for most single-section modifications, reducing waste and allowing experienced fabricators to achieve precise fitment without multiple splice joints that could compromise system efficiency or longevity.

This tubing works best for enthusiasts upgrading V6 or V8 powered vehicles, truck bed exhaust rerouting, or restoration projects requiring custom pipe fabrication. The 4-inch diameter accommodates moderate to high-flow applications without creating excessive backpressure. Installation requires welding equipment and basic metalworking skills; proper TIG or MIG welding technique ensures leak-free, structurally sound connections. Pair this tubing with PATRIOT EXHAUST flanges, hangers, and mandrel bends to create a complete, performance-oriented exhaust system that improves flow characteristics while maintaining factory-quality appearance.
