The Ultimate Buying Guide: Your 6.7 Cummins Delete Kit Explained
So, you’re thinking about a 6.7 Cummins delete kit. This guide will help you understand what to look for. We’ll cover the important stuff so you can make a smart choice.
Key Features to Look For
When you shop for a delete kit, keep these things in mind.
- Completeness: Does the kit have everything you need? This means all the pipes, gaskets, and hardware. Some kits might miss small but important parts.
- Fitment: Make sure the kit is made for your specific 6.7 Cummins year and model. A kit that doesn’t fit right causes big problems.
- Ease of Installation: Some kits are easier to put on than others. Look for kits with clear instructions and good design. This saves you time and frustration.
- Material Quality: The parts should be made from strong stuff. We’ll talk more about materials later.
Important Materials
The materials used in a delete kit really matter.
- Stainless Steel: This is a top choice. Stainless steel is strong and resists rust. It lasts a long time.
- Mild Steel: This is okay, but it can rust over time, especially in wet or salty conditions. It’s usually cheaper.
- Aluminum: Some parts might be aluminum. It’s light but can be less strong than steel.
Factors That Improve or Reduce Quality
A few things can make a delete kit better or worse.
- Welding Quality: If parts are welded, check for clean, strong welds. Bad welds can break.
- Gasket Material: Good gaskets stop leaks. Look for durable gasket materials that can handle heat and pressure.
- Design and Engineering: Kits designed by people who know Cummins engines are usually better. They fit well and work as they should.
- Brand Reputation: Some brands are known for making good parts. Doing a little research on the brand helps.
User Experience and Use Cases
People use delete kits for different reasons.
- Performance: Many owners want more power and better fuel economy. Removing emissions equipment can help with this.
- Simplicity: Some people just want to simplify their engine. Fewer parts mean less can go wrong.
- Maintenance: Emissions systems can be tricky and expensive to fix. Deleting them can save money on repairs.
- Off-Road Use: Delete kits are often used on trucks that are only driven off-road. This is because emissions laws apply to street-driven vehicles.
Remember, deleting emissions equipment might not be legal everywhere. Always check your local laws before making changes.
10 Frequently Asked Questions about 6.7 Cummins Delete Kits
Q1: What exactly is a 6.7 Cummins delete kit?
A: A delete kit is a set of parts that replaces the factory emissions control systems on your 6.7 Cummins engine. This usually includes the EGR (Exhaust Gas Recirculation) system and the DPF (Diesel Particulate Filter).
Q2: Why do people install delete kits?
A: People install them to improve engine performance, increase fuel efficiency, and simplify engine maintenance. They can also save money on costly emissions system repairs.
Q3: Are delete kits legal?
A: In many places, it is illegal to remove or tamper with emissions control devices on vehicles driven on public roads. These kits are often intended for off-road use only.
Q4: What are the main parts in a typical delete kit?
A: A typical kit includes a DPF delete pipe, an EGR delete kit (which includes block-off plates and sometimes new coolant lines), and sometimes a muffler delete pipe.
Q5: Will a delete kit affect my truck’s warranty?
A: Yes, installing a delete kit will almost certainly void your truck’s powertrain warranty. Manufacturers can deny warranty claims if they find emissions modifications.
Q6: How difficult is it to install a delete kit?
A: Installation difficulty varies. Some kits are straightforward for someone with basic mechanical skills. Others might require more specialized tools or knowledge.
Q7: Do I need to tune my truck after installing a delete kit?
A: Yes, a custom tune or programmer is usually required. The truck’s computer needs to be told that the emissions equipment is gone, or it can cause check engine lights and performance issues.
Q8: Can a delete kit improve my truck’s fuel economy?
A: Many users report better fuel economy after installing a delete kit. This is because the engine doesn’t have to work as hard to burn off soot from the DPF.
Q9: What happens if I get caught with a delete kit on a street-driven vehicle?
A: You could face fines, have your vehicle impounded, or be required to reinstall the original emissions equipment.
Q10: Where can I find good quality delete kits?
A: Look for kits from reputable aftermarket parts suppliers that specialize in diesel performance. Reading reviews and checking material quality are important steps.
