The Redback Extreme Duty Exhaust for 76‑Series Wagon (2007–2016) with Auxiliary Fuel Tank is a rugged 3″ turbo‑back exhaust system designed specifically to accommodate additional/auxiliary fuel tanks mounted ahead of the rear differential. Built from durable 409 stainless steel tubing and made in Australia, this exhaust features 4‑bolt, 10 mm thick flange plates, heavy‑duty hanger brackets, pressed fire‑ring gaskets, and a removable ¼″ NPT plug boss for optional EGT sensor installation. It offers flexibility with either a 5″ round straight‑through resonator for a balanced sound or a muffler‑delete (pipe‑only) configuration for maximum exhaust flow and aggressive tone. The system is coated with premium heat‑proof paint to resist corrosion, heat, and rough off‑road conditions. It’s engineered for vehicles without DPF but fitted with an auxiliary / long‑range fuel tank, and is backed by a 10‑year manufacturer warranty. Typical installation time is around 2–2.5 hours.
