The Ultimate Guide To Deleting The Dpf On Your 6 7 Cummins

---

What’s the Deal with the Diesel Particulate Filter (DPF)?
Your Cummins’ DPF is basically there to play environmental superhero, capturing soot and other particles that diesel engines love to produce. But when that filter starts clogging up, you’re looking at potential performance issues—lower horsepower, higher fuel consumption, and eventually a whole lot of frustration. The good news? A DPF delete can clear up those problems and give your truck some serious breathing room.

Why Go for a DPF Delete on Your 6.7 Cummins? Deleting the DPF isn’t just about skipping a few annoying maintenance tasks—it can actually unlock several key perks for your truck:
Better Fuel Economy: Ditch the DPF and you’ll notice fewer fuel stops. Your engine’s going to work a lot more efficiently, which translates into fuel savings. Boosted Power: A free-flowing exhaust means your Cummins gets to stretch its legs, giving you that extra horsepower, torque, and throttle response you’ve been craving. Reduced Maintenance Costs: No more cleaning or replacing that pesky filter, saving you some cash in the long run. Longer Engine Life: Less backpressure equals less heat buildup, and that’s a win for your engine’s health over time. Jump over to our 6.7 Cummins DPF Delete Kit Collection.
The Legal Side of Things Before you dive into your DPF delete, it’s important to keep in mind that this mod can run into some serious legal roadblocks depending on where you’re located. Many places have strict regulations about tampering with emissions systems. So, make sure you’re up to speed on all your local laws before proceeding. Dynovox always recommends staying on the right side of the law.
What You’ll Need for the Job A successful DPF delete requires a couple of key components:
DPF Delete Kit: This includes everything you need—exhaust pipes, clamps, and any other hardware to replace the DPF. DPF Delete Tuner: Reprogramming your truck’s computer is crucial. Without it, your Cummins won’t run right after the DPF is removed. Step-by-Step: How to Perform a 6.7 Cummins DPF Delete Here’s a quick run-through of how to get that DPF off your rig:
Unplug the Battery: Always a good first step—disconnect the negative cable to avoid any unwanted sparks. Remove the DPF: Locate the filter in your exhaust system and carefully take it out. Remember to disconnect any sensors and wiring. Install Your DPF Delete Kit: Follow the instructions to bolt in your new kit, ensuring everything’s snug and secure. Reprogram the ECM: Use the DPF delete tuner to adjust your engine’s control module. This step ensures your truck runs smoothly post-delete. Reconnect and Fire It Up: Once everything’s in place, reconnect the battery and start the engine. Listen for any unusual sounds and make sure no warning lights pop up. Check for Leaks and Test Drive: With the engine running, inspect the exhaust for leaks. After that, take your truck for a spin to make sure everything’s performing as expected. Keeping Your Cummins in Top Shape After the Delete Now that your DPF is a thing of the past, here’s what you need to do to keep your 6.7 Cummins humming:
Stick to Oil Change Intervals: Your engine will stay cleaner and happier if you stay on top of regular oil changes. Watch Exhaust Temps: Keep an eye on your exhaust gas temperature (EGT) to prevent your engine from overheating. Routine Inspections: Give your exhaust system and engine a once-over every now and then to catch any wear or leaks early. Use Quality Diesel Fuel: Treat your Cummins to the best diesel you can find—it’ll run better and last longer. Ready to Take the Plunge? Jump over to our 6.7 Cummins DPF Delete Kit Collection.
