Overview

This Australian-made 2.5″ Outback Exhaust System suits the Toyota Landcruiser 105 Series HZJ105 with the 4.2L 1HZ diesel (1998–2007). It replaces the entire factory system from the extractors to the tail pipe, improving exhaust flow, throttle response and durability for touring, towing and off-road use.
