FITMENT
- 2013–2018 6.7L Dodge Ram Cummins 2500 & 3500 Pickup Turbo Diesel.
- Note: Does NOT fit Cab & Chassis (3500 / 4500 / 5500 C&C) models.
DESCRIPTION
Product Overview
- Factory 6.7L Cummins engines can suffer from exhaust restriction, intake contamination, and increased thermal stress caused by the factory emissions system. The OEM DPF and catalytic converter increase exhaust backpressure and trigger regeneration cycles, while the EGR system recirculates soot into the intake, contributing to carbon buildup and reduced airflow.
- The Cummins Package addresses these restrictions with a 4" DPF/CAT race pipe, EGR cooler delete, and high-flow throttle valve delete tube. This complete airflow upgrade helps reduce exhaust restriction, improve intake flow, and support cleaner, more efficient 6.7L Cummins performance.
Key Features
- High-Flow DPF/CAT Race Pipe: Replaces the restrictive factory DPF and catalytic converter with a 4" pipe to improve exhaust flow and reduce restriction.
- EGR Cooler & Valve Delete: Removes the factory EGR cooler and valve assembly to help reduce soot buildup and eliminate common EGR-related failure points.
- High-Flow Throttle Valve Delete: Replaces the restrictive OEM throttle valve with a smooth airflow path to improve intake efficiency and throttle response.
- Reduced DPF Regeneration Cycles: Eliminates the need for active DPF regeneration, helping reduce unnecessary fuel consumption and improve overall efficiency.
FAQ
Q: Does removing the factory throttle valve cause any change when turning off the engine?
A: Slightly. The factory throttle valve helps smooth engine shutdown by restricting airflow when the key is turned off. Without it, the engine shuts down normally by cutting fuel, which may result in a slightly more noticeable diesel shutdown sound.
Q: What should I do with the stock EGT and O2 sensors removed from the factory DPF pipe?
A: Once custom delete tuning is flashed, these sensors are inactive. Unplug them, but don't leave the factory harness plugs exposed to dirt and moisture. We recommend using Harness Plugs to snap over your OEM connectors and prevent pin corrosion.
Q: What other upgrades work well with this kit?
A: For the best overall airflow upgrade, we recommend pairing this kit with a CCV Reroute Kit or a 5" DPF Delete Exhaust System to further reduce intake contamination and improve exhaust flow.
Q: Do I need to cut or modify my factory exhaust rubber hangers to install the 4" race pipe?
A: No. The 4" race pipe features pre-welded, factory-style mounting hangers that slide directly into your OEM rubber isolators for a hassle-free, bolt-on fitment.
