Best Exhaust for 79 Series LandCruiser with DPF: The 2025 Buyer's Guide
The DPF-equipped 79 Series V8 has restricted factory exhaust flow that limits throttle response and exhaust gas temperature management. A quality aftermarket exhaust improves both while keeping the vehicle road legal. This guide covers the main suppliers.
1. Manta Pro
3-inch stainless steel turbo-back system retaining the factory DPF. Quality fabrication, proven Australian-made reputation. $1,800-$2,800 fitted. The popular choice for owners who want road-legal performance without tuning complexity.
2. Redback
Budget-friendly 3-inch system. $1,500-$2,400 fitted. Adequate quality for moderate use, less premium fabrication than Manta or GSL but functionally similar performance gains.
3. GSL Fab
Custom-fabricated 3-inch or 4-inch system for specific build requirements. $2,200-$3,500 fitted. Best for owners who want a tailored solution and are willing to pay for custom fabrication.
4. Outback Hi-Flow
Mid-range option with hi-flow catalytic converter and DPF retained. $1,600-$2,500 fitted. Quality competitive with Redback at similar price.
5. DPF Compatibility
All quality aftermarket exhausts for the post-2016 DPF V8 retain the factory DPF and remain road-legal. Improved flow assists DPF regen by reaching the higher exhaust temperatures needed for soot incineration. DPF delete kits exist but are illegal for road use in Australia.
6. Tuning to Realise Gains
An exhaust upgrade alone typically delivers 5-15 kW. Pairing with a quality ECU tune unlocks the full potential - typically 175-195 kW at the engine. Tune costs $800-$1,800 from reputable shops with dyno verification.
