Australian-made 3″ turbo-back Outback Exhaust system for Toyota LandCruiser 80 Series 4.2L 1HDT wagon (1990–1998). 409 stainless, mandrel-bent, bolt-on fit with muffler options.
This Australian-made 3″ turbo-back exhaust system from Outback Exhausts is designed for the Toyota LandCruiser 80 Series HDJ80 with the 4.2L 1HDT turbo diesel engine (1990–1998). Built from durable 409 stainless steel, it replaces the full factory system from the turbo outlet to the tail pipe, improving flow, sound and overall performance. The mandrel-bent design maintains consistent internal diameter, helping turbo efficiency and exhaust evacuation under load.
The system runs outside the chassis and mounts directly to OEM locations for a clean, bolt-on installation with no welding required. Outback Exhausts supplies fasteners and gaskets (turbo gasket reused), ensuring correct fitment. Customers can select a resonator/small muffler for a quieter note or choose the pipe-only option for a stronger exhaust sound.Â
