3” OUTBACK EXHAUST SYSTEM to suit TOYOTA Landcruiser – 79 SERIES UTE SINGLE CAB 4.2L 1HZ DTS Turbo Upgrade 1999 ON (TURBO BACK)

Description

Overview

This 3″ Outback Exhaust turbo-back system suits the Toyota LandCruiser 79 Series single cab running the 4.2 L 1HZ diesel engine with a DTS turbo upgrade (1999–2007). Outback Exhausts builds the system in Australia using mandrel-bent 409 stainless steel, which increases exhaust flow and sharpens throttle response. It handles towing, touring and off-road use with confidence. Because the system replaces the factory exhaust from the turbo back, it provides smoother flow and stronger response across the rev range. The direct-fit design aligns with the factory mounting points, so installation remains straightforward and accurate.

The pipe-only configuration gives drivers the freedom to choose their preferred sound level or add a muffler to meet compliance needs. Its robust 409 stainless steel construction resists corrosion and heat, while the mandrel-bent design maintains consistent pipe diameter for reliable performance improvements. Outback Exhausts engineers and manufactures the system locally, delivering proven quality for Australian 4×4 conditions.
