6.7L Cummins 5" Turbo-Back DPF Delete Pipe with Muffler for 2016 Ram 2500

6.7L Cummins 5 Inch Turbo-Back DPF Delete Pipe with Muffler (2013-2018)

This 6.7L Cummins 5" turbo-back exhaust DPF delete pipe with muffler is designed for 2013-2018 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. This system replaced the entire factory exhaust system from the turbocharger outlet to the tailpipe, removing the diesel particulate filter (DPF) and diesel oxidation catalyst (DOC), thus eliminating significant exhaust back pressure.

The unique feature of this system is its built-in muffler, which, while retaining the performance gains from removing the DPF, provides a more balanced exhaust note suitable for everyday driving.

What You Can Get from This 5" Turbo-Back DPF Delete Pipe with Muffler Upgrade

1. T-409 Stainless Steel – High Temperature Resistance, Corrosion Resistance

This product uses T-409 stainless steel, making it more suitable for diesel exhaust environments compared to common OEM-style aluminized exhausts.

Its main advantages are:

• Higher temperature resistance
• More corrosion resistance
• More suitable for long-term use and complex road conditions
• More suitable for modification and long-term service than ordinary original equipment materials

This is "not a one-time modification, but a long-term upgrade."

2. Significantly Reduced Back Pressure – Faster Turbo Response

Original DPF and DOC are the biggest "bottlenecks" in the exhaust system, causing high back pressure, making the turbo sluggish and the throttle dull. This system uses a 5-inch large-diameter + DPF removal + turbo backpressure design to completely clear the exhaust passage. You will find that after installation, your truck's turbocharger builds up pressure faster, and the low-end torque response is more direct.

3. Complete Elimination of Regeneration Cycle – Fuel Savings, Reduced Maintenance

DPF regeneration is one of the most troublesome issues with original equipment systems. Frequent active regeneration not only wastes fuel (each regeneration consumes approximately 0.5-1 gallon of diesel), but also leads to oil dilution, increased engine wear, and the DPF itself is an expensive wear part (replacement costs can reach $2,000-$4,000). This system directly removes the DPF, eliminating the burden of long-term maintenance.

4. Balanced Exhaust Sound with Muffler

Most DPF delete pipes use a competition pipe design without a muffler, resulting in an overly direct sound that can easily produce an annoying drone during high-speed cruising. This product incorporates a muffler while retaining performance advantages, providing a deep, robust, and present exhaust sound that is not overly noisy.

5. Reduced Exhaust Temperature (EGT) – Improved Reliability

The back pressure created by the factory DPF significantly increases EGT. Under high load conditions, excessively high exhaust temperatures are one of the main causes of shortened turbocharger and engine life in diesel engines. This 5-inch large-diameter, straight-through design allows exhaust gases to escape quickly, effectively reducing exhaust temperature by 100-200°F. This translates to a safer engine operating environment and reduces potential risks such as turbo seal failure caused by high temperatures.

Performance Comparison: 5" Turbo-Back DPF Delete Pipe vs Stock

Expected performance improvements: better exhaust flow, lower drag, better throttle response, enhanced high-load driving performance, and a more practical performance foundation for future upgrades.

Note: Actual performance improvements depend on tuning, auxiliary modifications, and the overall condition of the vehicle.

How to Choose Between Turbo-Back Exhaust with & without Muffer

If you're torn between a 5-inch turbo-back DPF-removal exhaust with or without a muffler, the main differences lie in sound control and performance characteristics.

• Buyers seeking the ultimate sound and a more uncompromising tuning style are advised to choose the version without a muffler.
• For buyers who want high-performance exhaust flow but don't want the massive sound of a straight-through exhaust, the version with a muffler is a better choice.

Who Is This Muffled DPF Delete Pipe Best For?

This exhaust system is designed for diesel vehicle owners who want the performance and reliability improvements of DPF removal but are concerned about excessive noise. If you meet the following criteria, this exhaust system is ideal for you:

• You frequently tow your vehicle and want to reduce exhaust gas temperature (EGT) and achieve more responsive throttle, but don't want an overly harsh exhaust sound.
• You live or drive in an area where excessive exhaust noise can be a nuisance.
• You prefer a deep, powerful exhaust note that is attention-grabbing without being overly noisy.
