The Redback Extreme Duty Exhaust for 78‑Series Troop Carrier (2007–2016) is a 3″ turbo‑back system engineered for high flow performance and durability in heavy‑use and off‑road applications. Built from 409 stainless steel tubing and Australian‑designed, it features 4‑bolt 10 mm flanges, extreme‑duty hanger brackets, pressed fire‑ring gaskets, and a removable 1/4″ NPT EGT sensor boss for monitoring. The exhaust can be ordered with or without a high‑flow diesel catalytic converter, and offers sound options: large straight‑through muffler, resonator, or muffler‑delete (pipe-only). Its heat‑proof coating ensures long‑term resistance to heat and corrosion under tough conditions. Installation typically takes ~2–2.5 hours, and the system is backed by a 10‑year manufacturer warranty.
