FITMENT
- 2007–2009 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- Factory 2007–2009 6.7L Cummins engines can suffer from exhaust restriction and intake contamination caused by the factory emissions system. The stock DPF and catalytic converter increase exhaust backpressure, while the EGR system and throttle valve introduce soot and restrict airflow into the intake.
- The Cummins Package addresses these factory restrictions with a 4" DPF/CAT delete race pipe and complete EGR valve & cooler delete. This upgrade improves exhaust and intake airflow, reduces soot buildup, and helps your operate more efficiently.
Key Features
- EGR Cooler Delete: Removes the factory EGR valve and cooler assembly to help reduce soot buildup, intake contamination, and common EGR-related issues.
- Throttle Valve Delete Tube: 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.
- Improved Turbo Response & Exhaust Sound: Reduced exhaust restriction helps improve turbo response while delivering a deeper, more aggressive diesel exhaust tone.
FAQ
Q: What should I do with the stock oxygen, pressure, and EGT sensors on the factory DPF?
A: Once custom ECM delete tuning is flashed and the 4" race pipe is installed, these sensors are no longer used by the engine. Unplug them from the factory wiring harness and tie the connectors up securely away from hot moving parts.
Q: Can I install this 4" race pipe without deleting the EGR cooler?
A: Yes, the race pipe can be installed separately, but pairing it with an EGR delete provides a more balanced airflow setup and helps ensure proper tuning compatibility.
Q: What is the main purpose of deleting the EGR system on a diesel engine?
A: EGR delete removes exhaust soot recirculation into the intake system, helping reduce carbon buildup and maintain cleaner airflow. It also eliminates common EGR-related issues such as cooler failures and coolant leaks.
Q: Can a leaking factory EGR cooler damage my diesel engine?
A: Yes. A cracked EGR cooler can allow coolant into the exhaust or intake system, causing coolant loss, white smoke, overheating, and potential engine damage.
