3” OUTBACK EXHAUST SYSTEM to suit TOYOTA Landcruiser – 105 SERIES WAGON DIESEL 4.2L HZJ105 1HZ DTS TURBO UPGRADE 1998 – 2007 (TURBO BACK)

Description

Overview

The 3″ Turbo Back Exhaust System from Outback Exhausts delivers a robust, high-flow solution for the 1998–2007 Toyota LandCruiser 105 Series (4.2 L HZJ105 / 1HZ DTS-turbo). Designed to work with factory-turbo or DTS turbo upgrades, this system replaces the stock exhaust with a true 3″ mandrel-bent mandrel tubing layout for maximum flow. It enhances exhaust flow, supports increased turbo output, reduces exhaust restriction and suits tough outback touring, towing and heavy-duty work environments.

Key Features

• Turbo-back layout — from turbo manifold back to rear exit (factory turbo or DTS upgrade compatible).
• Australian-made quality by Outback Exhausts ensuring durability for harsh conditions (touring, towing, off-road).
• Precision fitment for 105 Series Wagon Diesel 4.2 L HZJ105 / 1HZ DTS-turbo (1998–2007).
• Improved exhaust flow to complement turbo upgrades — helps realise gains from DTS turbo conversions.
• Worldwide shipping available from manufacturer.
