Exhaust Tubing - 1.500 18 Gauge - 5ft. Long

The Patriot Exhaust Tubing - 1.500 18 Gauge - 5ft. Long (H7748) is a straight exhaust pipe section designed for custom exhaust system fabrication and restoration work. This 60-inch section provides the core component needed to build, repair, or modify exhaust systems on street rods, race cars, trucks, and classic vehicles where precise diameter and wall thickness are critical to flow characteristics and durability.

The 1.5-inch diameter tubing delivers optimal scavenging and exhaust velocity for small-block engines and mid-range applications, while the 18-gauge steel construction provides sufficient wall strength to handle thermal cycling and internal pressure without excessive weight. The natural (unpainted) steel finish allows for welding and custom finishing to match your specific system requirements. At 3.75 pounds, this 5-foot length is manageable for one-person handling during fabrication and installation, yet substantial enough to form a core section of a complete exhaust run from manifold to rear axle or muffler inlet.

This tubing is ideal for builders, fabricators, and enthusiasts who need control over exhaust system geometry and construction. Whether constructing a tight-radius turn-down, splitter configuration, or axle-back system, the straight profile serves as the foundation for welding bends, couplers, and components into a custom layout. Patriot Exhaust tubing is widely stocked by shops that prioritize dimensional accuracy and consistency in exhaust work.

Steel exhaust tubing requires proper welding preparation and post-weld finishing to prevent corrosion. The natural mill scale finish will oxidize rapidly in service; most fabricators apply ceramic coating, stainless finish, or protective paint to extend system life and maintain appearance. This tubing is compatible with standard automotive welding equipment and standard pipe couplers, bends, and flanges in the 1.5-inch size class.
