Diesel pickups got their first emissions systems in the mid-2000s. Firstly the catalytic converters came into existence and then right after it, Exhaust Gas Recirculation (EGR) was introduced. In 2007, the laws made it mandatory to have Diesel Particulate Filter (DPF) installed in every vehicle. At last, in 2011, Selective Catalytic Reduction (SCR) also got itself introduced.

Why should anyone delete 6.7L Cummins? In the earlier days, EGR systems were decreasing the combustion efficiency of an engine. As emissions systems were relatively new for diesel trucks, the systems reduced the overall speed of the trucks. That’s where the same thought of the 1970s of removing your car’s emissions system came into existence.

6.7 Cummins Problems

Is anything perfect in this world? Have you ever asked yourself this question? You probably did. The answer is no. Nothing is perfect in this world. Although Cummins 6.7 is the best out there when power and torque (up to 1000+ lb-ft) is your concern, it isn’t totally problem-free. We’re going to state the problems here that you are probably going to face so that you are conscious about your vehicle’s near future.

Clogged Turbocharger

You have to compromise your truck’s performance if you have a faulty turbocharger or turbo actuator. People generally blame the emission control devices, especially the EGR for their turbocharger failure. Because the air that goes from the emission system into the turbocharger becomes dirty and emerges clog issues.

You should replace your faulty turbocharger as soon as you notice it. Because the newer ones are updated, and therefore you are not going to face any further issues. If you don’t replace the faulty turbocharger, you have to sacrifice strongness and longevity of your vehicle.

Exhaust Troubles

RAM trucks combined with Cummins 6.7 are absolute giants. You can either use it for daily use or for towing heavy loads on a regular basis, it won’t disappoint you in any case. But it has a common problem that owners and enthusiasts are pretty much aware of.

After taking a lot of driving, certain parts of the truck take a lot of loads and pressure. And thus its exhaust manifold loses its shape slowly and steadily. Well, don’t worry. There’s a simple solution to this problem. You can just replace the existing exhaust manifold with an aftermarket manifold. Some of them even last longer than the stock one!

EGR and DPF Issues

In 2007, 6.7 Cummins came into the existence by replacing 5.9 Cummins. 5.9 Cummins was very famous for its load-taking capability. 6.7 Cummins was introduced to tackle the emission laws. But countering both aspects, keeping the reputation of 5.9 Cummins, and managing emission laws at the same time was a bit hard task for 6.7 Cummins.

That’s when things started to fall apart. 6.7 Cummins started getting a bad reputation for its EGR and DPF problems here and there. People had to spend more bucks to keep their trucks on the road. Addressing this problem, experts came out with the solution of deleting the emission system. By deleting the emission system, you would the engine to run smoothly without facing any further problems.

Usual Check-Engine Light

Another common issue with the 6.7 Cummins is that even if you do have a completely okay vehicle, sometimes the dashboard will show an error code. Well, it is not because of some failures, but because your onboard computer failed to register the existence of a new part.

To get rid of this issue, experts recommend using a tuner. There are various tuners for different reasons. You can always get one in the aftermarket according to your need. A tuner will not only give you the update about what’s wrong with the truck but also will check and clear error codes.

Head Gasket Failures

Your engine’s head gasket can fail too due to over workload. Due to the failure, your engine’s completion can be downed. To survive this situation you may buy aftermarket parts. After solving this problem, the engine’s completion will be increased and it will be able to take more workload.

Injectors Going Bad

The 6.7 Cummins has got a high-pressure common-rail system. What does it do? It sends fuel to the engine. As the 6.7 Cummins has a better system, it works faster than any other previous system. But the injectors are not that much updated. They are pretty much the same as other diesel engines. That’s why they tend to wear out very often. You can replace the injectors to fix the problem.

6.7 Cummins EGR Delete

EGR is an important part of the engine’s emission system. EGR stands for Exhaust Gas Recirculation. What does EGR do? EGR redirects the exhaust gasses back to your engine. Though it complies with the emission laws by doing so, it significantly harms your vehicle’s engine by reducing performance. That’s why you should consider deleting the EGR.

We can present the mighty 5.9 Cummins as an example of what Cummins can do without the emission system. Actually, the 5.9 Cummins had emission systems too, in the form of a Catalytic converter, but they were not much effective. 6.7 Cummins has the updated emission systems like DPF, EGR, and SCR. And that’s where all the problem starts to emerge.

You can delete the EGR of your 6.7 Cummins with the available EGR delete kit compatible with your 6.7 Cummins version. The delete kits are available in any aftermarket. So you will not face many hassles finding them.

Cummins 6.7 Delete

What does the term ‘Cummins 6.7 Delete’ mean? It means to remove the emission system wholly or partly. We are going to describe the removal process of the emission systems very briefly.

The easiest of them is to remove the catalytic converters. You have to simply install a straight pipe in place of the converter. And you are done! Deleting an EGR system is a bit more complicated. You have to block the plates on the easiest side and put new exhaust up-pipes on the more difficult side.

The DPF and SCR (Selective Catalytic Reduction) deletion is also fairly easy. You have to just replace the exhaust system. However, all the EGR, DPF, and SCR deletion requires retuning of the engine computer.

You should always consider the state laws as they do not permit the removal of your emission systems. You can only use your deleted truck for off-road purposes.

6.7 Cummins EGR Delete Benefits

Are you in hesitation about deleting your 6.7 Cummins EGR? Take a break, and start reading from now on. We are going to state the benefits of removing your vehicle’s EGR valve. If you know the benefits, you may get a clearer picture of your decision.

Improved Engine Performance

Do you know how EGR works? It simply redirects the exhaust gasses back to the engine. Those dirty gasses can harm your vehicle’s engine pretty easily and lower the efficiency of the engine. Removing the EGR from the vehicle will sort the problem out.

Improved Fuel Economy

Mixing the engine with dirty gasses means lowering its efficiency. It will face more pressure while performing its actions. Thus it will eat more fuel than before. It is a simple equation, isn’t it? You can get rid of this problem by simply deleting your EGR valve with an EGR delete kit.

Do not need to worry about Emergency maintenance

Compromising your vehicle’s engine for a better emission output is never a good idea. It will cause not only problems for the engine but also create problems that emerge because of the dysfunction of the engine. Thus, you may have to stop from journeys quite often for emergency maintenance.

As long as you are nearby a repair shop or if you have the tuning kits, you are safe. But if you are not, you are in a world of problems. There’s always a chance that you will end up wasting a day or two. So, why take the risk when you can simply eliminate the problem by removing the EGR?

Voids warranty coverage

No dealer would want to fix a vehicle that has been run into problems while deleting the emission system. That would put an extra workload on them. Who wants that?

Limits use to off-road
