Check if this fits your vehicle
Tired of the restrictions and trouble caused by the factory DPF? Want more power but are worried that the noise and drone of a straight-pipe system will affect daily driving? This 5-inch DPF delete pipe with a high-performance muffler is the ultimate solution designed for you.
“Performance beast, yet still a gentleman—unleash the power without the noise.”
A 5-inch pipe is very large. Without a muffler, there can be a loud “humming” sound inside the cabin during highway driving, and prolonged exposure may cause dizziness. The muffler effectively filters out this low-frequency noise, making long-distance driving more comfortable. Compared with a straight-pipe system, the volume can be reduced by 30–40%.
It retains the authentic, deep rumble of a diesel engine while reducing harsh, sharp exhaust notes and excessive noise.
When entering or leaving a neighborhood, cold starting, or using the truck for daily transportation, it will not disturb neighbors because of excessive noise, and it is also less likely to attract attention from pedestrians or the police.
Simply put, the version with a muffler retains an enjoyable exhaust tone while also providing long-distance comfort and everyday practicality.
The greatest pain point for diesel truck owners is the high maintenance cost caused by the DPF and DEF systems. Owners of 2013–2018 Ram 2500/3500 trucks with the 6.7L Cummins share several common problems: frequent DPF regeneration wastes fuel, DEF crystallization causes blockages, and EGR carbon buildup reduces power. This 5-inch turbo-back DPF delete pipe with muffler can help address these problems at once.
This 5-inch exhaust pipe for 6.7 Cummins directly replaces the highly restrictive factory DPF, allowing the engine to "breathe" more freely.
When combined with ECU tuning, horsepower and torque can increase by 15–20%, and gains of 50–150+ horsepower are common.
Turbo lag is noticeably reduced, the throttle responds more directly, and acceleration and overtaking feel more confident.
During heavy loads or towing, it can effectively reduce the operating temperature of the engine and turbocharger, helping protect the engine.
It completely prevents the vehicle from entering power-limiting “Limp Mode” due to DPF clogging.
After removing the factory DPF, exhaust back pressure is greatly reduced and turbo response becomes faster. When combined with ECU tuning, horsepower can increase by 80–150 hp. Whether climbing hills, overtaking, or towing heavy loads, power is available whenever needed.
It eliminates the extra fuel wasted during DPF regeneration while improving engine efficiency. You will no longer need to buy DEF fluid at $2–$3 per gallon, and you will not need to worry about expensive repair costs caused by DPF clogging.
Many truck owners worry that removing the DPF will make the exhaust too loud or create uncomfortable highway drone. This version with a muffler sounds deeper than the factory system but is much more moderate than a straight-pipe setup—it sounds powerful without disturbing others, and long-distance driving will not be affected by low-frequency drone.
It is made from T409 stainless steel with a thickness of 2 mm, offering better high-temperature resistance and corrosion resistance than the factory aluminized pipe. Even after years of exposure to road conditions, it is not likely to rust, allowing one system to last for the long term.
The complete piping system installs in the factory mounting locations with bolts and includes all clamps and hangers. No cutting or welding is required. Owners with strong hands-on ability can install it themselves, with installation completed within 2 hours.
