A premium 409-stainless 2.5″ bolt-on exhaust system for 79 Series Toyota LandCruiser UTE (4.2 L 1HZ, 1999–2007), delivering better flow, stronger performance and rugged durability for touring and off-road use.
This 2.5″ Outback Exhausts engine pipe-back system is engineered for the Toyota LandCruiser 79 Series single cab running the 4.2L 1HZ naturally aspirated diesel engine (1999–2007). Built in Australia from durable 409 stainless steel, it offers improved exhaust flow, stronger sound and long-term reliability for touring, towing and off-road work. The mandrel-bent design reduces restriction compared to the factory system and delivers smoother performance without excessive cabin drone.
Designed as a direct bolt-on upgrade, the system reuses the factory mounting points and typically requires no welding, making it suitable for DIY installation or professional fitment. Sunshine Coast Diesel Tuning can supply and install this system as part of a performance upgrade package.
