A turbo-back exhaust system replaces the entire exhaust from the turbocharger outlet all the way to the tailpipe – the most complete exhaust upgrade available, and the one most 4WD and diesel ute owners mean when they talk about a "full exhaust". Because it's the biggest single change you can make to a diesel exhaust, a turbo-back system typically delivers the largest gains in flow, turbo spool and towing response of any exhaust upgrade, particularly on popular tourers like the LandCruiser, Patrol and D-Max. Emissions equipment such as the catalytic converter and DPF are included in the system design, so compliance depends on the specific kit – our DPF-back range is the street-legal alternative if you want to retain your factory DPF.

What's included in a turbo-back exhaust system?

A turbo-back system covers the entire exhaust from the turbocharger outlet through to the tailpipe – the front pipe, catalytic converter or DPF housing (as specified in the kit), mid-pipe, muffler and tailpipe.

Is a turbo-back exhaust legal in Australia?

Legality depends on whether the specific kit retains the required emissions equipment for your vehicle and state. A turbo-back system that removes the catalytic converter or DPF entirely is generally for off-road use only – our DPF-back range is the road-legal option that keeps factory emissions gear in place.

What's the benefit of a turbo-back exhaust for towing?

Reduced backpressure across the whole system can lower exhaust gas temperatures and improve turbo response under sustained load, which is particularly useful when towing a heavy trailer or caravan over long distances.

How does turbo-back differ from DPF-back?

A turbo-back system starts right at the turbo outlet, ahead of the catalytic converter and DPF, while a DPF-back system starts after the factory DPF and retains it. DPF-back is the more common street-legal choice for modern diesel utes.
