High-flow 3″ turbo-back exhaust system designed for Toyota Landcruiser 80 Series 4.2 L 1HZ engines with DTS turbo upgrade. Mandrel-bent 409 stainless-steel piping ensures improved flow, boosting performance and exhaust efficiency.
This 3″ Outback Exhaust system has been specifically engineered for the Toyota LandCruiser 80 Series Wagon (1990–1998) running the 4.2L 1HZ engine fitted with a DTS turbo upgrade. Designed as a full turbo-back replacement, it delivers increased exhaust flow, reduced back pressure and improved throttle response. The mandrel-bent 409 stainless steel construction ensures strength and consistency, making the system suitable for touring, towing and heavy off-road use. Thanks to its bolt-on design, it mounts directly to factory hangers, allowing for a straightforward installation without custom fabrication.
Owners seeking improved sound control can select between a resonator/small muffler configuration or a straight-through pipe for a more assertive exhaust note. The system is built in Australia and includes a 5-year warranty on the exhaust components, reinforcing its long-term reliability.
