FITMENT
- 2013-2018 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
- This Pipe is designed for standard leaf-spring pickup truck configurations.
- Does NOT fit trucks equipped with the factory-optional Rear Air Suspension or commercial Cab & Chassis (4500/5500) models.
DESCRIPTION
Product Overview
- While the 13–18 6.7L Ram boasts impressive factory power, its emissions system chokes it with failing DEF heaters, faulty quality sensors, and fragile NOx sensors that trigger 5-MPH Limp Modes.
- During use, factory DPF is continuously collecting irreversible ash until it becomes permanently plugged, making this 4" DP-Back pipe a simple bolt-on fix to replace the restrictive filters and rotting muffler in one go.
- Replacing your exhaust train from downpipe to bumper ends fuel-guzzling regeneration cycles, while the integrated high-flow muffler ensures a quiet, drone-free towing experience for a truck with plenty of life left.
Key Features
- Premium T-409 Stainless Steel Built: Heavy-duty T-409 SS to provide superior heat resistance and protect your undercarriage from severe winter road salt and rust pitting.
- High-Flow Muffler Integration: Features a straight-through performance muffler that eliminates restrictive emissions without the obnoxiously loud or raspy note of a full straight pipe.
- Drastic EGT & Backpressure Reduction: Maximizes exhaust gas velocity to significantly lower sustained EGTs, protecting turbo and head gasket under heavy load conditions.
- Bypass Failing DEF Heaters: Allows you to completely shut down the failure-prone SCR system, permanently bypassing the notorious built-in DEF tank heater and its costly repair bills.
FAQ
Q: Why do 13–18 DEF heaters fail so often, and what does it cost to fix?
A: Submerged in corrosive fluid, the heater seals crack from winter freeze-thaw cycles, shorting out the electronics. Because it is integrated, dealerships force a full tank replacement costing $600–$1,200. This pipe deletes the system so it can never fail again.
Q: Will this kit solve my constant NOx sensor failure codes?
A: Yes. The fragile NOx sensors are mounted directly on the factory SCR section. Since this kit replaces that entire section and deactivates the monitoring software, the sensors are removed entirely, saving you $300–$500 in recurring replacement costs.
Q: What is "permanent DPF ash clogging," and how does this pipe prevent it?
A: Regens only burn soot, leaving behind permanent metallic ash. Because high-torque 13–18 Ram engines produce massive power, they plug filters with ash faster than older trucks—forcing a $2k–$k factory replacement. This pipe deletes the filter before it chokes engine.
Q: How much will my Exhaust Gas Temperatures (EGTs) drop after installation?
A: Significantly. The restrictive factory emissions stack acts like a brick wall, trapping extreme backpressure and heat. Swapping it for this high-flow 4" system allows the engine to breathe freely, drastically lowering EGTs—especially when towing heavy loads up steep grades.
