Problems with the Amarok Diesel Particulate Filter are well documented. The Amarok runs an active DPF system that traps harmful diesel particulates in a honey comb structure, and then burns them off as the DPF flow is reduced. In the Amarok, often the soot left behind after the burn cycle can build up and cause a permanent blockage and expensive failure
Signs your DPF is failing include reduced engine performance, higher fuel consumption along with more frequent burn cycles.
Remove your DPF, and upgrade the performance of your Amarok today with a full stainless steel PPD Performance system
Specifically designed and engineered for the VW Amarok 2L Twin turbo TDI400 & TDI420 (2012+), this 3" DPF Delete stainless system unleashes the performance and sound that they should have had from the factory!
Similar systems sell for three times the price!

Note: An ECU map is recommended when deleting your DPF.
Most post-2007 diesel vehicles are fitted with a Diesel Particulate Filter (DPF) for emissions reasons, however there are a few disadvantages to this device; including constant maintenance and repairs. When your car is used only for off-road use, there are a number of benefits to removing your DPF.
So what is this DPF?
Due to the combustion process of diesel motors, and the different quality of diesel fuels available, the engines produce left over diesel particles which are then released into the atmosphere via the exhaust. Emissions standards have become stricter over the years, therefore the diesel particulate filter was born. It is a device fitted in the exhaust that is designed to remove ash or soot from the exhaust gases of a diesel motor, by forcing the gases through a porous channel wall consisting of thousands of channels to collect the diesel soot.
Some of these filters are single-use and must be replaced once they are full of soot, whereas others can be actively burnt off via the engine control unit (ECU) by increasing the temperature, or by injecting raw fuel in to burn it off - known as filter regeneration. However eventually all filters efficiency decrease over time until they are non-serviceable and must be replaced.
There are number of different filter technologies such as wall flow filters, ceramic fiber filters, metal flow through filters, and even paper filters, all with the intention of fine filtration of diesel particles.
So how does this affect you and your vehicle?
Disadvantages of the DPF system
Unfortunately for most emissions related devices, they can be party poopers especially for performance enthusiasts.
As the DPF is an added restriction in the exhaust (think catalytic converters) it automatically causes extra backpressure in the exhaust, resulting in slightly reduced performance (sluggish feel).
The other problem with DPF fitted vehicles are the constant maintenance and servicing required by the owner such as replacing the DPF when it is 'full', a cleaning cycle of every 12 months, 1000 hours, or 60-100,000km's depending on the manufacturer recommendations.
Regardless of the frequency of the vehicles DPF regeneration to 'burn off', they do eventually become fouled to the point of being unserviceable and requiring full replacement.
Failure to continue this upkeep results in reduced exhaust flow which leads to reduced power output, reduced fuel efficiency, and faulty or cracked DPF's causing full replacement.
Wouldn't it be nice to have one less thing to worry about?
The DPF Delete and the Benefits
Firstly, we must advise that DPF's are an emissions device and therefore we can only recommend a DPF delete kit be fitted for off-road vehicles. With that out of the way there are number of seriously worthwhile benefits to having the DPF removed from the exhaust system.
1. It removes the need to service the DPF at regular intervals (cleaning, replacement)
2. A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs
3. Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
4. Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles
To realise the true benefits of having the DPF removed, a PPD Performance ECU remap is highly recommend to maximise the fuel mapping and remove any DPF error codes that may arise from the DPF delete.
If you are in the market for a diesel 4x4, don't let a vehicle fitted with a DPF deter you from ownership! You can avoid problematic DPF issues with a PPD Performance DPF delete or full turbo back exhaust system and ECU remapping to suit your vehicle. Not only does this result in a more reliable, maintenance free experience during your ownership, but you will also have the added benefits of more power and a more efficient motor.
PPD Performance have engineered a number of turbo back exhaust systems (including DPF delete) for most popular 4x4's. Check for your vehicle here today!
Note: DPF removal components are designed for off-road use only. Please consider this before purchasing and installing
At PPD Performance, all of our exhausts proudly feature:
Mandrel Bent Piping
PPD Performance exhausts comprise of mandrel bent, stainless pipe work, delivering uncompromising flow, performance, and sound. Mandrel bending involves placing a mandrel inside the piping, before it is bent to shape. In comparison; cheaper press bending from other manufacturers squashes the tube as it is bent, reducing flow.
304 Grade Stainless Steel
Tired of your mild steel exhaust systems rusting out after a year or less? Time to shop for a stainless steel system? There’s still some things you need to be aware of. Our competitors typically advertise their exhaust products as stainless steel. Most don't stipulate the differences between ferretic 409 grade stainless steel and austenitic 304 stainless steel.
Significant differences exist between the metals that make one better for performance exhaust applications than the other. Let us explain
The corrosion resistance of your 4x4 exhaust depends on the content of chromium and nickel found in the alloy. 409 grade stainless steel is used by many manufactures due to its medium strength, formability and very low cost. Typically, 409 grade stainless steel has a chromium content of between 10.50% - 11.75% and a nickel content of less 0.50%.
Why do we use 304 grade stainless steel piping for 4x4 performance exhausts? Because it is more resistant to rusting than ferretic based stainless steels such as 409. However, because of its low ferrous content, 304 can develop a golden colour when exposed to high heat over time. In fact, the ferrous metal content is so low that magnets won’t stick to it, making the identification of 409 and 304 grade stainless steel very easy.
Put simply, 304 grade stainless is the best value material used in the 4x4 exhaust game when strength, corrosion resistance and performance are at the top of your list of priorities.
Type 304 steel is engineered with chromium and nickel content and proves to be resistant to oxidation, corrosion, and durability.
Together with a polished finish - it is a great choice for your 4x4 offering excellent corrosion resistance from exhaust emissions, moisture and beach exposure.
Bolt on Installation
All PPD Performance exhausts are designed to follow the same orientation and layout as the factory exhaust, making for easy bolt on installations. Our systems utilise the standard hanger locations, which means you don't have to use anything other than the factory rubbers.
All PPD Performance exhaust systems include a fitting kit comprising of all required bolts, gaskets and clamps.
At PPD Performance, we understand you need peace of mind. All PPD Performance exhaust systems are covered by a confidence inspiring 2 year warranty.
