5" DPF Delete Exhaust System for 2013-2018 Ram 6.7L Cummins Turbo Diesel
Unlock the full potential of your 2013-2018 Ram 2500 or 3500 with the 6.7L Cummins Turbo Diesel using this mandrel-bent DPF (Diesel Particulate Filter) delete exhaust system. The factory DPF is one of the most restrictive components in the OEM exhaust system, creating significant backpressure that robs horsepower, torque, and fuel economy. Our DPF delete pipe replaces the restrictive factory filter with a free-flowing 5" mandrel-bent exhaust for maximum performance.
Why Delete Your 6.7L Cummins DPF?
The Diesel Particulate Filter on the 6.7L Cummins captures soot particles and periodically burns them off through a regeneration (regen) cycle. While designed to reduce particulate emissions, the DPF system creates several well-documented problems:
-
Excessive Backpressure: The DPF creates significant exhaust restriction, reducing turbo efficiency, increasing EGTs (Exhaust Gas Temperatures), and limiting horsepower potential.
-
Fuel Dilution: During active regeneration, raw diesel fuel is injected into the cylinders during the exhaust stroke, washing down cylinder walls and contaminating engine oil.
-
Reduced Fuel Economy: Regeneration cycles consume extra fuel, and DPF backpressure reduces combustion efficiency. Owners commonly report 2-4 MPG improvement after DPF delete.
-
Regen Hassles: Short trips, idle time, and cold weather can prevent complete regeneration, leading to "Drive to Clean" messages, limp mode, and eventual DPF clogging requiring $2,000+ replacement.
-
Turbo Lag: Reduced exhaust flow through the DPF increases turbo lag and throttles throttle response – especially noticeable when towing heavy loads.

Premium Build Quality
-
T409 Stainless Steel Construction: Mandrel-bent T409 stainless steel maintains consistent 5" internal diameter throughout – no crush bends that restrict flow. Superior corrosion resistance compared to aluminized steel alternatives.
-
Mandrel Bending Technology: Unlike crush-bent exhaust systems that reduce internal diameter at every bend, our mandrel-bent pipes maintain full 5" diameter for maximum exhaust flow and minimum backpressure.
-
OEM Hanger Points: Pre-welded hanger brackets match factory exhaust hanger locations for a true bolt-on installation with zero fabrication.
-
Factory-Fit Flanges: CNC laser-cut flanges ensure a perfect seal at all connection points. No exhaust leaks, no gasket issues.
Performance Benefits
-
+15-25 HP / +30-50 lb-ft Torque: Eliminating DPF backpressure allows the turbo to spool faster and the engine to breathe freely.
-
2-4 MPG Fuel Economy Improvement: No more regeneration fuel consumption. Cleaner, more efficient combustion without DPF restriction.
-
Lower EGTs: Free-flowing exhaust reduces exhaust gas temperatures by 100-200°F under load – critical for towing safety and turbo longevity.
-
Improved Turbo Response: Reduced backpressure means faster turbo spool and sharper throttle response.
-
Better Exhaust Note: Straight-pipe sound with a deep, aggressive diesel tone.
Installation Overview
This DPF delete exhaust system is engineered for straightforward bolt-on installation. All factory hanger points are pre-welded, and the kit includes all necessary clamps and hardware. Estimated installation time: 2-4 hours with basic hand tools, a saw or exhaust cutter (for removing the factory DPF), and a floor jack or lift. No welding required.
Frequently Asked Questions
Q: Will this fit my 2016 Ram 3500 Crew Cab Long Bed?
A: Yes. This kit is designed to fit all 2013-2018 Ram 2500 and 3500 models with the 6.7L Cummins. It fits all cab configurations including Regular Cab, Crew Cab, and Mega Cab with both short and long bed options.
Q: Do I need a tuner after DPF delete?
A: Yes. The factory ECM will detect DPF removal and may trigger warning lights or limp mode. A compatible tuner is required to disable DPF-related functions and optimize the engine calibration for the new exhaust configuration.
Q: Is this a complete bolt-on kit?
A: Yes. The kit includes all pipes, flanges, clamps, hangers, and hardware needed for installation. No additional parts or fabrication required.
Q: What's the difference between T409 and T304 stainless steel?
A: T409 stainless offers excellent corrosion resistance at a better value point. For the majority of climates and applications, T409 provides decades of reliable service. T304 (used in marine environments) costs 50-70% more with minimal additional benefit for most truck owners.
Q: How does DPF delete affect towing performance?
A: Towing performance improves significantly. Lower EGTs mean safer heavy-load operation, and reduced backpressure allows the engine to maintain power more efficiently on long grades. Many owners report 100-200°F EGT reduction when towing after DPF delete.
Q: Will this exhaust pass emissions testing?
A: This product is designed for off-road and competition use only. It is not intended for use on vehicles subject to emissions regulations. Please check your local and state laws before purchase.
Q: What tools do I need for installation?
A: Basic hand tools (sockets, wrenches), a floor jack or lift, an exhaust cutter or reciprocating saw, and penetrating oil for factory bolts. Installation time is approximately 2-4 hours.
