FITMENT
- 2007.5–2009 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- Factory 6.7L Cummins engines suffer from extreme backpressure and intake carbon contamination. The stock catalytic converter and DPF restrict exhaust flow, forcing frequent high-heat regen cycles that waste fuel and spike EGTs. Simultaneously, the factory EGR and throttle valve force soot-laden exhaust into the intake, clogging runners and choking airflow.
- The 6.7L Cummins Delete Package eliminates all primary bottlenecks at once. Combining a 4" DPF/CAT race pipe, EGR & throttle cooler valve delete, this system maximizes drive pressure, drastically lowers EGTs, stops carbon sludge, and unlocks your engine's true torque potential.
Key Features
- EGR Cooler Delete: Removes the factory EGR and cooler assembly to help reduce soot buildup, intake contamination, and common EGR-related issues.
- Throttle Delete: Replaces the restrictive factory intake throttle valve assembly with a smoother airflow path, improving intake flow efficiency to the engine.
- Eliminates DPF Regeneration Cycles: Removes the need for active DPF regeneration, helping reduce unnecessary fuel consumption and improving overall operating efficiency.
- High-Flow DPF/CAT Delete Race Pipe: Replaces restrictive factory DPF and catalytic converter components with a smooth 4" pipe, reducing exhaust restriction and improving exhaust flow under load.
FAQ
Q: What is the main performance benefit of installing this complete 6.7L Cummins kit?
A: This package addresses both intake and exhaust restrictions at once. You get dramatically faster turbo spooling, significantly lower EGTs during towing, complete elimination of DPF regeneration fuel loss, and clean air going into your intake manifold.
Q: Does installing the 4" DPF race pipe require cutting my factory exhaust?
A: No. This 4" race pipe is engineered to bolt directly in place of the factory DPF and catalytic converter sections using stock mounting points and clamp connections.
Q: Why is the Throttle Valve Delete included in this 6.7L Cummins kit?
A: The stock throttle valve is a major airflow bottleneck designed mainly to force EGR gas into the engine. Replacing it with a straight delete tube eliminates this restriction and maximizes intake CFM for better throttle response.
Q: Will this 4" straight race pipe create annoying interior cab drone?
A: Because it eliminates the restrictive DPF and muffler components, it will increase exhaust volume noticeably. While it creates a deep diesel tone, cabin drone is mild unless paired with a full 5" straight-pipe system.
