The Hidden Gems in a 6.7 Cummins DPF Delete Kit
A well-crafted DPF delete kit is more than just pipes and clamps—it’s the key to unlocking the engine’s raw potential. In your kit, you’ll find:
· Downpipe: The bridge between the turbo and the rest of your exhaust system.
· Extension pipes: Essential for adapting the system to your truck’s unique body style, whether it’s a MegaCab or CrewCab.
· Tailpipe: The final piece, channeling exhaust gases with newfound efficiency.
Each component is designed to seamlessly replace your restrictive OEM parts. And yes, you’ll need a truck tuner, not just to keep that pesky check-engine light at bay but to tune the ECU into harmony with your upgraded exhaust.
Preparing to Embrace Change
Before you begin, take a moment to connect with your machine. Let the engine cool. Roll out your tools. Feel the anticipation of transformation. A safe, stable work environment is key—jack stands are your best friends here. The next steps will demand patience and precision, but the rewards will echo in every rev of the engine.
Step-by-Step: How to Install a DPF Delete on a 2013-2018 6.7 Cummins
Transforming your 6.7 Cummins with a DPF delete is a journey that takes patience, precision, and the right tools. Below, you’ll find a step-by-step guide, optimized from the original instructions, to help you bring your truck’s performance to life.
Step 1: Preparation—Setting the Stage for Greatness
Before diving in, ensure your workspace and tools are ready.
· Let the truck cool down completely to avoid burns.
· Safely lift and secure the truck using a jack and jack stands. Stability is key to your safety.
· Gather your tools: ratchets, torque wrench, WD-40, gloves, safety goggles, and, of course, your DPF delete kit.
Take a moment to inspect the kit components and confirm compatibility with your 2013-2018 Dodge RAM 6.7 Cummins. This includes checking the downpipe, extension pipes, and clamps.
Step 2: Removing the Stock DPF System—Breaking the Chains
Disconnect Sensors and DEF Injector:
Carefully unplug all sensors, including the DEF injector, SCR system, and diesel particulate filter (DPF). Ensure all wiring is safely tucked away to avoid damage.
Loosen Clamps and Flanges:
Start at the tailpipe. Loosen the clamp holding the exhaust system to the truck. Then unbolt the flanges connecting the DPF and SCR to the exhaust.
Remove the DPF and SCR:
Gently lower the DPF and SCR system from the truck. These components can be heavy, so proceed with caution.
Remove the Downpipe:
At the turbo, locate the band clamp securing the downpipe. Loosen the bolt enough to release the clamp. Use a flathead screwdriver to pry the clamp loose at three points. Save the band clamp, as it will be reused in the new installation.
Step 3: Installing the DPF Delete Kit—Crafting a New Path
Prepare for Installation:
Place all necessary clamps on the pipes before connecting them. This will save you time and frustration during assembly.
Install the Downpipe:
Secure the new downpipe to the turbo using the stock band clamp. Tighten it enough to hold the pipe in place, but keep it loose enough to allow for alignment adjustments later.
Install the Main Pipe:
Attach the primary pipe to the downpipe. Insert the metal hangers into the factory rubber insulators for stability.
Add Extension Pipes:
For MegaCab/SB models, attach pipe 50012; for CrewCab/LB models, use pipe 50022. Ensure these pipes align correctly and are securely attached.
Install Muffler and Tailpipe:
Attach the 6196 muffler, followed by the 21756 over-axle pipe and 21757 tailpipe. Secure all hangers into OEM rubber isolators.
Adjust Factory Isolators:
On some models, you may need to relocate the factory rubber isolators to metal hangers near the rear axle for proper fitment.
Step 4: Fine-Tuning—Bringing It All Together
Align the Exhaust System:
Adjust the positioning of the pipes for proper clearance and aesthetic alignment. Make sure there is enough space between the pipes and surrounding components to prevent heat damage.
Tighten All Connections:
Starting at the turbo, work your way back, evenly tightening all clamps and connections. This ensures a secure and leak-free system.
Calibrate with a Tuner:
Use your truck tuner to update the ECU. Disable any DPF-related sensors, clear fault codes, and optimize engine settings for the new system.
Step 5: Final Check—Testing Your Work
· Start the Engine: Listen carefully for any unusual sounds, such as exhaust leaks or vibrations.
· Inspect for Leaks: Check all connections to ensure they are tight and leak-free.
· Take a Test Drive: Monitor the truck’s performance and enjoy the improved response and power.
By following these steps, you’ll unlock the true potential of your 6.7 Cummins. Take your time, enjoy the process, and remember: the road ahead just got a lot more exciting.
