Pre-September 2016 V8 (no DPF): wider range of legal options including straight-through 3-inch systems, $1,500 to $2,800 fitted.

Shop 79 Series Exhausts

1. Pre-September 2016 V8 (No DPF)

Pre-DPF V8s have the widest range of legal exhaust options including straight-through 3-inch systems with no DPF restriction. $1,500-$2,800 fitted. Gains 8-18 kW alone, 25-45 kW with quality tune. Manta, Redback, GSL, Outback, Hulk all offer compatible systems.

2. Post-September 2016 DPF V8 (to Late 2024)

DPF must be retained for road legality. DPF-compatible 3-inch systems from Manta Pro, Redback DPF-Spec, GSL Fab, Outback Hi-Flow. $1,600-$3,500 fitted depending on supplier. Gains 5-15 kW alone, 25-40 kW with quality tune. DPF delete kits exist but are illegal for road use.

3. New 2.8L 1GD-FTV (Late 2024 Onward)

Smaller exhaust market currently. Manta and Redback offer 79 Series 2.8L systems at $1,400-$2,500 fitted. Gains more modest than the V8 (3-10 kW alone, 10-25 kW with tune) due to the narrower torque band.

4. Common Configurations

Turbo-back 3-inch stainless is the standard touring/working spec. Cat-back systems (replacing only the section after the catalytic converter) are simpler installations and 30-40% cheaper but deliver smaller gains. Headers/manifolds are rare on the 79 Series - the cost-benefit is poor without an engine rebuild.

5. Sound Profile

V8 era exhausts deliver a distinctive deep diesel V8 note - particularly noticeable on the Manta Pro and GSL Fab. 2.8L four-cylinder exhausts are quieter and less characterful. Buyers who specifically want the V8 sound usually upgrade to a more open system; 2.8L buyers usually upgrade for performance rather than sound.
