Understanding Delete Kits for 6.7 Cummins Engines
Before diving into the specifics of the best delete kits available, it is essential to understand what a delete kit is and its implications for your 6.7 Cummins engine. Delete kits are aftermarket modifications designed to remove or bypass factory-installed emissions components like the DPF and EGR systems. The purpose of these kits is to optimize engine performance by reducing back pressure, increasing airflow, and allowing for a more aggressive tuning profile.

- Attribute: Aftermarket Modification
- Value: Removed Emissions Components
Types of Delete Kits Available
There are various types of delete kits on the market, and understanding these can help you make an informed decision:
1. Complete Delete Kits
These kits provide everything necessary to completely remove the DPF and EGR systems. They often include pipes, programming tools, and all necessary hardware for installation.
2. EGR Delete Kits
