Overview

This 3″ turbo-back exhaust system from Outback Exhausts is engineered for the Toyota LandCruiser 105 Series Wagon (1998–2007) with the 4.2L diesel engines 1HZ, HZJ105 and 1HDF-TV factory turbo. Manufactured from durable mandrel-bent 409 stainless steel, the system replaces the factory exhaust from the turbo outlet to the tail pipe. It delivers improved flow, a deeper exhaust note and long-term durability suited to touring, towing and off-road conditions.
