So you’ve decided to delete your 6.7 Cummins diesel truck. Deleting your diesel means removing the exhaust gas recirculation or EGR system along with the diesel particulate filter or DPF. This opens up the exhaust, increases power, and improves fuel economy. But how much does a 6.7 Cummins delete kit cost and is it worth the investment?
Deleting your 6.7L Cummins is not cheap, but for many truck owners, the benefits outweigh the costs. Delete kits typically range from $500 up to $2,500 or more depending on the components included. The good news is, with the right kit and tuner, you can gain over 100 horsepower and 200-300 pound-feet of torque. You’ll also notice an improvement of 2-4 miles per gallon. If performance and fuel economy matter to you, a 6.7 Cummins delete kit may be worth serious consideration. Here’s what you need to know to get started.
What Is a 6.7 Cummins Delete Kit?
A 6.7 Cummins delete kit removes components from your truck’s exhaust system to improve performance. By deleting the exhaust gas recirculation (EGR) valve and diesel particulate filter (DPF), your Cummins engine can breathe easier and make more power.
- The EGR valve recycles exhaust gasses back into the engine to reduce emissions. Deleting it prevents exhaust gasses from re-entering the cylinders, allowing for a cleaner burn and more oxygen. This can boost your horsepower and torque.
- The DPF is a filter that captures soot and particulates from the exhaust. Removing it eliminates the blockage and backpressure, reducing strain on your engine. Expect gains of 30-50 horsepower or more after a DPF delete.
Of course, deleting emissions components means your truck will no longer meet EPA regulations and can’t be used on public roads. But for off-road use or racing, a 6.7 Cummins delete kit is a popular upgrade. Many kits are available from aftermarket brands that include high-flow exhaust manifolds, pipes, and mufflers to replace the stock components.
Performance gains, rumbling exhaust notes, and the joy of customizing your truck are all reasons people choose to delete their 6.7 Cummins. If you’re looking for more power and an aggressive sound, deleting the emissions on your diesel pickup may be worth considering!
Top EGR Delete Kits for the 6.7 Cummins
If you’ve got a 6.7L Cummins diesel and want to unleash its full potential, deleting the exhaust gas recirculation (EGR) system is one of the best mods you can do. EGR systems reduce emissions but choke your engine and reduce power. Deleting it will boost performance and fuel economy.
Two of the top EGR delete kits for the 6.7L Cummins are:
- Flo Pro’s 4″ EGR Delete Kit: This full kit includes a block off plate to seal the EGR passage, EGR valve delete pipe, and a new intake manifold pipe. It’s a straightforward install and nets gains of 50-100 horsepower.
- MMP’s EGR Delete Kit: Another popular, full delete kit using high quality components. It includes billet aluminum EGR block off plates, intake tubes, and all necessary hoses and clamps. Can provide 60-120 extra horsepower.
Deleting your EGR isn’t too complicated for a mechanically inclined do-it-yourselfer. You’ll remove components like the EGR valve, tubes, and cooler, then install the block off plates and new intake tubes in their place. Some tuning to disable the EGR codes and adjust fueling may be required.
If you want the EGR gone for good from your Cummins, an EGR delete kit is the way to go. You’ll open up your engine to gulp in more air, gain power and mpg, reduce soot buildup, and get rid of that pesky check engine light for good. An EGR delete is one of the best bang-for-your-buck mods for performance and engine longevity.
How Much Does It Cost to Delete a 6.7 Cummins?
Deleting your 6.7L Cummins diesel engine can unlock more power and improve performance, but at a cost. The total cost will depend on the specific components you choose to include in your delete kit.
Basic Delete Kit ($500-$1000)
A basic kit will remove the diesel particulate filter (DPF), diesel oxidation catalyst (DOC) and selective catalytic reduction (SCR) components. Deleting these reduces exhaust backpressure and can increase power by 10-15 horsepower. It includes replacement pipes to connect the engine to your existing exhaust. This is a good, budget-friendly option if you primarily want reduced regeneration cycles and a little more power.
Full Hot Rod Kit
For maximum power gains of 25 horsepower or more, a full “hot rod” kit is your best bet. In addition to removing the DPF, DOC and SCR, it will replace your stock exhaust manifold, turbocharger and downpipe with free-flowing performance parts. High-flow air intakes are also typically included. These kits require custom tuning to optimize the changes. They produce an aggressive exhaust note and may not be street legal in some areas due to emissions regulations.
Installing a delete kit yourself in your garage is definitely doable to save money, but for the best results it’s best left to a reputable diesel performance shop. Between parts and professional installation, you can expect to pay $3,000-$6,000 or more for a high-quality 6.7L Cummins delete kit, depending on how extensive of a kit you choose. While not cheap, deleting your Cummins can significantly enhance your driving experience through more power, less regeneration, and an unrestricted exhaust sound. For many diesel enthusiasts, the improved performance and soundtrack are well worth the investment.

Conclusion
So there you have it. Deleting a 6.7 Cummins isn’t cheap, but for many diesel enthusiasts, the performance gains and throaty growl of an open exhaust make the investment worthwhile. At the end of the day though, you have to weigh the pros and cons for your own needs and budget. If you’re looking for major horsepower and the roar of a big rig, the full delete kit might call your name. If you just want a little extra rumble without breaking the bank, a DPF back exhaust could do the trick. Whatever you decide, make sure to check your local regulations to ensure you stay within legal limits. The choice is yours – now get out there and unleash that diesel!
