Afterburner Thrust Tubes - 3in x 12in (pair)

The Afterburner Thrust Tubes - 3in x 12in (pair) by FLOWTECH are essential exhaust extensions designed for custom automotive builds where aggressive styling meets functional exhaust flow management. These dual tubes are engineered for enthusiasts and mechanics who demand both aesthetic impact and performance-oriented exhaust routing. Whether you're building a custom hot rod, street machine, or performance project vehicle, Afterburner Thrust Tubes deliver the classic look of side-exit or rear-exit exhaust extensions while maintaining proper scavenging characteristics and heat dissipation away from critical underbody components.

Manufactured by FLOWTECH, a trusted name in performance exhaust systems, these 3-inch diameter thrust tubes feature 12-inch length for maximum visual presence and tailored exhaust exit positioning. The pair weighs 5.45 lbs combined, indicating robust wall construction designed to withstand sustained high-temperature cycles and vibration without degradation. The tubes are optimized for seamless integration with existing exhaust manifold or collector outlets, allowing builders to create custom exit configurations that enhance underbody visibility while optimizing exhaust gas velocity and preventing turbulent backpressure accumulation in the primary piping.

Ideal for street rod fabrication, restomod projects, and custom performance applications, the Afterburner Thrust Tubes work best in systems where dual-exit design and centerline exhaust exit are priorities. Installation requires welding or slip-fit coupling to your existing exhaust system, making them compatible with a wide range of engine platforms and configurations. Professional installation is recommended to ensure proper alignment, secure attachment, and thermally-safe routing away from fuel lines, wiring, and suspension components. These tubes are particularly popular in traditional hot rod builds, custom muscle car restorations, and street performance vehicles where authentic exhaust aesthetics are non-negotiable.
