Exhaust Tubing - 2.250 18 Gauge - 5ft. Long

The Exhaust Tubing - 2.250 18 Gauge - 5ft. Long from Patriot Exhaust is a straight steel exhaust pipe engineered for custom exhaust system fabrication and modification work. This 60-inch section serves as a foundational component for builders constructing custom exhaust systems, replacing damaged piping, or extending existing runs on vehicles ranging from street machines to performance builds. Whether you're routing exhaust through a tighter engine bay, creating dual exhaust splits, or fabricating a complete custom exhaust assembly, this tubing provides the core material needed to achieve proper flow and fit.

Constructed from steel in a natural finish, this exhaust tubing features a 2.25-inch outer diameter and 18-gauge wall thickness that balances structural integrity with workability for welding and bending. The 18-gauge specification provides adequate durability for street and mild performance applications while remaining thin enough for precision shaping without specialized equipment. At 5 pounds, the tubing is substantial enough to handle thermal cycling and exhaust gas velocity without flex, yet light enough for convenient handling during installation. The straight, 60-inch length offers maximum flexibility—sections can be cut to precise measurements, welded into custom configurations, or combined with mandrel bends and elbows to create optimized exhaust paths that maintain scavenging efficiency.

This tubing is ideal for mechanics, fabricators, and enthusiasts tackling custom exhaust projects where off-the-shelf systems don't fit the application or desired routing. It works across carbureted classics, LS-swapped vehicles, engine transplants, and modified engines requiring clearance-critical exhaust layouts. Compatibility spans virtually any engine platform when paired with appropriate collectors, reducers, and flanging work. Installation requires welding equipment and basic metalworking skills; ensure proper joint preparation and heat management to maintain the integrity of your exhaust system. For complete systems, combine with mandrel bends, mufflers, and resonators to achieve both performance and sound characteristics matched to your build goals.
