The Essential Buying Guide for Your 2012 6.7L Cummins Delete Kit
Thinking about deleting the emissions equipment on your 2012 6.7L Cummins? You are not alone. Many truck owners choose this path to improve performance, reliability, and save on maintenance costs. However, buying the right delete kit is crucial. This guide helps you pick the best one for your truck.
Key Features to Look For
A good delete kit does more than just remove parts. It replaces them with strong, reliable components. Look closely at what each kit offers.
1. Complete Component Coverage
- EGR (Exhaust Gas Recirculation) Replacement: The kit must include a solid, well-made block-off plate or tube to seal the EGR cooler port. This is very important.
- DPF (Diesel Particulate Filter) Replacement Pipe: You need a high-flow exhaust pipe to replace the bulky DPF unit. Check that it matches your existing exhaust system size (usually 4-inch).
- DOC (Diesel Oxidation Catalyst) Delete: Some kits include a pipe to remove the DOC as well. This simplifies the exhaust path even further.
2. Necessary Tuning Support
Removing emissions equipment requires reprogramming the truck’s computer (ECM). Make sure the kit clearly states it is compatible with the necessary tuning devices or custom tunes. A kit without proper tuning support will cause your truck to run poorly or not at all.
3. Hardware Quality
The kit should come with all the necessary gaskets, bolts, and clamps. High-quality stainless steel hardware lasts much longer against rust and heat.
Important Materials Used in Delete Kits
The materials used directly affect how long your delete kit lasts and how well it performs.
Exhaust Components (DPF/DOC Pipes)
- 304 Stainless Steel: This is the best material. It resists rust and corrosion very well, even in harsh winter road salt conditions. It costs more but is worth the investment for longevity.
- Mild or Aluminized Steel: This is cheaper. It works fine initially, but it rusts much faster than stainless steel, especially if moisture gets trapped inside.
Block-Off Plates and Fittings
Look for thick, precision-cut metal for EGR block-offs. Cheap, thin metal warps easily under high engine temperatures. Billet aluminum or thick stainless steel offers the best seal.
Factors That Improve or Reduce Quality
Not all kits are made equal. Pay attention to these details to ensure you get a quality product.
Quality Boosters:
- Precision Fitment: Kits designed specifically for the 2012 6.7L Cummins fit perfectly. Poorly made parts require forcing or modification, which causes leaks.
- Smooth Welds: Good welds mean the pipe is strong and exhaust flows smoothly.
Quality Reducers (Watch Outs):
- Missing Gaskets: If the kit requires you to reuse old, worn-out gaskets, expect leaks soon after installation.
- Vague Instructions: Clear, step-by-step instructions save hours of frustration during installation.
User Experience and Use Cases
Why do people install these kits? The results often influence which kit they choose.
Performance and Towing
For those who tow heavy loads or race, a quality delete kit improves exhaust flow. This lets the turbo spool faster and keeps Exhaust Gas Temperatures (EGTs) lower. Users report noticeable power gains after proper tuning.
Reliability and Maintenance
The factory emissions systems are complex and prone to failure. Deleting these parts removes common failure points, saving you thousands in potential repair costs down the road. This makes the truck more reliable for daily driving or long hauls.
10 Frequently Asked Questions (FAQ) About 2012 6.7L Cummins Delete Kits
Q: Is deleting the emissions equipment legal?
A: In most states, deleting emissions equipment makes the truck illegal for on-road use. Check your local and state laws before purchasing and installing, as fines can be high.
Q: Does a delete kit affect my warranty?
A: Yes. Removing factory emissions equipment instantly voids any remaining powertrain warranty related to the engine or drivetrain components.
Q: What kind of tuning do I need?
A: You must have custom tuning loaded onto your ECM. Stock software will not work with the deleted components, and your truck will likely go into “limp mode.”
Q: How much louder will my truck be after installing the DPF delete pipe?
A: The truck will be noticeably louder than stock, especially under acceleration. It sounds much more like a traditional diesel engine. Muffler options are sometimes available if you want less noise.
Q: Can I still pass an emissions test with a delete kit installed?
A: No. Once the DPF and EGR are removed, the truck will fail any required visual or sniffer emissions inspection.
Q: What is the easiest material to install?
A: Stainless steel parts usually fit well because they are manufactured precisely. The difficulty comes from removing the old, rusted factory components.
Q: Will deleting hurt my fuel economy?
A: Many users report a slight improvement in fuel economy because the engine does not have to fight backpressure from the DPF.
Q: Are there any sensors I need to trick or delete?
A: Yes. The tune handles most sensor issues, but some kits provide dummy sensors or plugs to fool the ECM into thinking the DPF and other components are still attached.
Q: How long does the installation usually take?
A: For an experienced mechanic, the physical installation might take 3 to 5 hours. If you are doing it yourself, plan for a full weekend, as removing rusted bolts is tough.
Q: Should I delete the DOC along with the DPF?
A: Most people delete both for the best flow and simplicity. The DOC removal pipe is usually included in full delete kits.
