Our 3” exhaust system for the Prado replaces the factory exhaust system, right up to the DPF (DPF-back systems), or right up to the turbo (turbo back systems). It gives some good gains, particularly bringing the turbo boost in much earlier, adding responsiveness down low in the rev range. In the interests of keeping in-cab noise as low as possible, we incorporated two straight-through mufflers into the exhaust system.
This keeps the exhaust noise level close to the factory levels, with no annoying drone inside the cab. The mandrel bends and straight through mufflers on our Prado exhaust system, ensure the highest possible flow, and along with that comes maximum performance and fuel economy.
The latest model Prado comes from the factory with a Diesel Particulate Filter. These are an emissions device designed to control the amount of soot emitted from the exhaust system. We have two options in our exhaust range – DPF back (similar to a “cat back” system on a petrol vehicle), or turbo back (replacing the entire factory exhaust system, including the DPF).
The turbo back system does require a recalibration of the vehicle’s Engine Control Unit (ECU) to remove certain functions associated with the DPF system. This is intended for off-road or race use only.
In the future, we plan to introduce a high flow DPF system which will give you the benefits of a performance exhaust system while ensuring compliance with road rules.
