There’s no denying the advantages of the Duramax L5P, GM’s latest diesel engine. This engine can reduce cathode, reduce emissions, and oxidize diesel.
However, L5P also has many disadvantages. Some of them can be expensive replacements, limited performance, or easy to clog.
To end the above problem, you can use the Duramax L5P delete kit. To learn about the pros and cons, you can refer to the post below.
What Is The Duramax L5P DPF System?
Duramax L5P DPF System
DPF stands for diesel engine particulate filter, a system that allows a vehicle to improve its environmental impact each time it operates. When burning fuel, some internal combustion engines, like diesel engines, will create by-products.
We will encounter a mixture of exhaust gasses such as CO and CO2 next to a series of dust and diesel particles, coal dust.
The DPF can capture wastes in physical form and burn them all instead of releasing them straight into the environment.
In modern vehicles, the environmental protection filter system has not only the Diesel particulate filter but also several other components. With L5P, the system will have more DOC, DEF, SCR, and EGR.
Among the above parts, the DOC will be the first place exposed to the exhaust gas with the task of catalyzing diesel oxidation.
The gas mixture will then pass through the SCR and DEF to minimize residual gas. The final product will pass through the DPF, and physical residues will stay in this filter while gasses continue to escape.
Particularly with Duramax L5P, SCR and Diesel particulate filter appear together in the same pipe in this exhaust pipe.
With this feature, the correct cycle on this engine model will be in order from the exhaust to DOC, then SCR and DPF, and finally silencer. Compared to all other mechanisms, the EGR system is entirely separate from the exhaust pipe.
The mechanism of EGR operation requires this part to be located near the exhaust gas source to collect these agents first. The airflow will then begin to separate and return to the combustion chamber for reuse.
What Does The L5P DPF Delete Remove?
L5P Delete remove
As for the Duramax L5P engine system, using the delete kit to manipulate the Diesel particulate filter will also affect the remaining mechanisms.
While the rest of the systems separate the diesel particulate filter, the L5P connects them all. So, when you delete DPF, DOC, SCR, and DEF will disappear.
The disappearance of one of these four elements will directly disable the operation of all three remaining elements.
Only EGR is not affected by the deletion process. The position of the exhaust gas recirculation system is quite far from the exhaust pipe, so you will not find any relationship between these two assemblies.
This difference also prevents us from using delete kits for EGR and vice versa. All your manipulation efforts will be in vain if you choose the wrong tool to work.
To clearly explain the connection between DOC, SCR, DEF, and DPF, you need to know that the essence of the delete kit is a replacement set of metal tubes.
Removing the Diesel particulate filter also means removing a piece of exhaust pipe that integrates all four mechanisms.
After manipulation, you insert the pipe of the L5P delete kit at the vacant position to form a closed path like the original. The difference is that the new duct will be empty inside instead of integrating exhaust and dirt filters.
What Is The Use Of the L5P Duramax Delete Kit?
The Use Of the L5P Duramax Delete Kit
The L5P is removing the exhaust system. When it was first released, many users commented that removing L5P was impossible because the manufacturer has made many changes to ensure that users cannot affect the control system.
However, quite a few public manufacturing companies provided modular access methods to remove L5P throttling after a while. Until now, finding products that allow erasing and adjusting the emission system is no longer too difficult.
An L5P erasure kit will focus on removing DPF. Deleting it will also make the remaining systems unable to function as before. Therefore, deleting the DPF means you have deleted the SCR, DPF, and DOC system.
The removal cannot affect the EGR exhaust system because this system is not under the influence of the removal kit.
How To Delete Duramax L5P DPF System?
Before you operate, you must prepare for problems that may arise when you interfere deeply with the system via the filter.
Deviations, loss of warranty, and legal factors are issues you must take care of. Any careless action can have severe consequences for the vehicle.
To work with the Duramax L5P system, you will need two tools: the L5P delete kit and the detector with the ability to delete the filter.
The connections between the Diesel particulate filter and the vehicle are not only in the physical aspect but also in the electronic communication aspect. Therefore, the process will not be complete if we only manipulate simple mechanical parts.
L5P Delete Kit
A basic L5P delete kit will have a replacement exhaust with a feather cover, so we can only fix the pipe to the car’s body. Some products have a fixed pin that you can operate without fixing screws.
In addition, you also have another option of specialized replacement products for a single part. It will be the most straightforward option if you want to keep details other than DPF.
These essential products are usually iron or cast iron with average machining quality and few accessories. To own this type of L5P delete kit, you only need to spend about $ 300 to $ 400. The difference will depend on the device’s length, size, and build quality.
Besides the regular erasers, we can choose the erasers that come with the reverse exhaust. Instead of conventional cast iron or iron pipes, this delete kit will provide you with aluminum or stainless steel pipes.
The properties of these materials are durable and flexible, so you can rest assured of using them for a long time.
You also get reverse exhaust pipes and a set of tones to go with it in one package. With all of the above factors, an L5P delete kit of this type can cost anywhere from $500 to over $1,000
DPF removal detector
You have two options for performing the DPF removal detector.
First, try custom tuning. Every exhaust system has sensors. Your task is to adjust these sensors. In case of difficulty, you can try changing the regenerative cycles.
Second, you can look to the H&S detector. This impressive removal kit has been discontinued. Therefore, you can currently only find a used detector.
You can also find several devices available on the Internet. However, it is pretty challenging to be sure about the power supply as well as the actual efficiency of the device.
L5P EGR Delete Kit Overview
L5P EGR Delete Kit
The EGR system comes with an exhaust cooler. This addition prevents the system from negatively affecting engine performance.
However, this is not to say that the system is not without its drawbacks. EGR will deposit harmful soot particles into the engine. Besides, the system’s cooler is also quite fragile.
By removing the EGR system, you will prevent soot accumulation. At this time, a large amount of clean air will circulate. The greater the flow, the faster the turbocharger accelerates, and the stronger the throttle response.
The removal will ensure faster and more efficient engine coolant circulation compared to using the EGR system.
Unlike DPF, you won’t get rid of EGR quickly. To remove the DPF, you only need to remove the direct bolted exhaust section. With the EGR, you have to do more work. Specifically, you will have to lock the EGR valve and plug in the hose.
L5P Delete Cost
To perform steps to remove the filter on the L5P, you will need at least $1000 to $2000, depending on the accessories we use.
The cost for the device will range from $200 to $1000, while other necessary accessories will be the remaining amount.
If you need professional workers’ help, the fee will be higher because you need to pay additional labor costs. Compared to repairing the DPF, the replacement costs much less.
You can cut costs even further if you buy more for a group of people. The retail policy of many manufacturers mostly favors bulk purchases with good discounts.
Duramax L5P DPF Delete Pros
Reliability
Too many exhaust systems will bring you a lot of trouble because each method has its problems. For example, SCR is error-prone, DEF requires too much fluid, and DPF is prone to clogging.
Obstruction will cause the engine to frequently malfunction and operate worse.
You will have to spend a lot of money to solve the above problems. Besides, too many filters will also waste your diesel fuel.
Another issue related to oil is cleanliness. Soot deposited behind the filter will stick to the engine, damaging the oil.
Oil mixed with waste will negatively affect the engine performance.
Efficiency
A series of these filters all create back pressure in the exhaust system. This operation negatively affects the overall performance of the turbo.
The power can exceed 100 WHP when spinning if the upper filter is removable. If you want to upgrade your turbo, removing L5P Duramax is a wise choice.
If you don’t really master the relevant skills, you can ask for help from an expert. Using a removal kit without knowledge can cost you more money than you think.
Duramax L5P Delete Cons
Besides the advantages, manipulating Diesel particulate filters on L5P also has some issues you must pay attention to before using it.
Impact on the environment
DPF and related systems help clean exhaust gasses when returned to the outside environment. Removing all of these components will also remove all mechanisms blocking air pollutants. Exhaust gas full of toxins will spray straight out and harm yourself and many people around.
Lost warranty
Brands will never accept a modified and tampered device under warranty.
Because they cannot know what you have manipulated and how those actions will affect the car, if we, unfortunately, encounter damage, we will have to ask for workers from outside facilities.
Legal issue
Some areas will not allow vehicles with Diesel particulate filters removed to operate on the road. If you continue to use it, the risk of you getting into legal trouble is exceptionally high.
FAQs.
Should You Wipe Your L5P DPF System?
To answer the above question, you must consider the advantages and disadvantages of eliminating the system.
Performance and reliability are the reasons you should remove the filter. Meanwhile, legal issues and environmental impacts are obstacles you must consider before performing this operation.
You should only discard the filter when the SCR and DOC are inefficient. Alternatively, if you use source code, you can also try removing the DPF.
If maintaining the above emissions system causes your financial problems, you should choose to implement DPF removal.
If your exhaust system is still functioning correctly, you should not proceed with the removal. Maintaining a DPF system will ensure your vehicle can pass emissions tests and operate legally.
L5P Duramax Kit Cons?
Eliminating the emissions system offers several great benefits. However, before deciding to remove it, you need to consider a series of important issues such as:
- Reduced resale value: when the emission system is clear, the vehicle’s warranty is forfeited. And most dealers won’t repurchase your car because of technical legality concerns.
The same problem occurs when you want to sell your car directly through an intermediary. Today, car buyers are hesitant to use a model with no emissions system because they can face fines at any time.
- The installation must be done yourself: for legal reasons, dealers or vehicle repair centers will not reinstall the emissions system.
- Environmental problem: Removing the DPF system will cause the engine to emit more emissions into the environment.
- Legal issue: your car doesn’t pass the emissions tests. Some localities can prosecute you by law if the emissions from x exceed the permissible threshold.
- Difficulty finding a tuner that can clear the DPF: Large companies providing equipment for this activity have had to pay any fines. And in the following time, all devices for DPF erasure will be discontinued.
- Price: Not everyone can afford hundreds of dollars for a rarely used kit. Many often go to the repair shop with a cost of only a few dozen dollars.
