The 6.7L Cummins is a diesel engine that was first released in 2007. Since then, it has become one of the most popular engines for trucks and SUVs.
While it’s an extremely reliable engine, it can also be expensive to maintain. In addition, the 6.7L Cummins is not emissions-compliant in all states.
As a result, some owners may decide to delete their engines in order to avoid costly repairs or unexpectedly high emissions fees.
However, remember that deleting an engine is a permanent change that cannot be undone, so its essential to weigh the pros and cons carefully before making a decision.

Benefits of 6.7 Cummins DPF Delete
6.7 Cummins DPF delete kits have become quite popular in recent years, particularly among truck owners who do a lot of off-roading.
There are a number of benefits to deleting the DPF, including improved engine performance and fuel economy.
Perhaps the most significant benefit is the reduced maintenance required. The DPF is responsible for filtering out soot and particulates from the exhaust gas, and over time it can become clogged.
This can lead to reduced engine performance and fuel economy. By deleting the DPF, you can avoid this potential problem altogether.
Additionally, many people find that their truck sounds better without the DPF in place.
Drawbacks of 6.7 Cummins DPF Delete
Some truck owners choose to delete their DPF in order to save money on diesel exhaust fluid and filter replacements.
But before you do that, it is important to note that DPF delete kits are illegal in many states. This means if you are caught with a deleted DPF, you could face serious penalties.
In addition, deleting your DPF can void your truck’s warranty, so if something goes wrong down the road, you’re on your own.
And also, without a DPF, your truck will produce more soot and particulate matter, which can lead to engine damage and reduced fuel economy.
