FITMENT
- 2007–2009 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- 2007–2009 6.7L Cummins engines face heavy breathing restrictions from OEM emissions hardware. The stock DPF and catalytic converter create severe exhaust backpressure, while the EGR system and throttle valve choke the intake with dirty soot and turbulent airflow.
- This Cummins Upgrade Package pairs a high-flow 4" DPF/CAT delete race pipe with a full EGR valve and cooler delete kit. By removing primary exhaust bottlenecks and isolating soot from the air charge, it restores uninhibited airflow, eliminates intake carbon sludge, and optimizes engine efficiency under load.
Key Features
- Eliminate exhaust backpressure with a smooth 4-inch race pipe that replaces the restrictive factory DPF and catalytic converter for full, unrestricted flow.
- Stop abrasive exhaust soot from entering the intake by removing the EGR cooler and valve with precision block-off plates and a coolant bypass hose.
- Hear and feel the difference with sharper turbo response and a deeper, more aggressive diesel exhaust tone once the factory silencers are out of the way.
- Trust rugged T-409 stainless steel construction that survives years of diesel exhaust heat without rotting, cracking, or warping like cheaper alternatives.
FAQ
Q: What should I do with the stock oxygen, pressure, and EGT sensors on the factory DPF once it’s removed?
A: After custom ECM tuning is flashed, these sensors are no longer active. Unplug them from the factory wiring harness and secure the connectors up and away from hot or moving components.
Q: Can I install the 4″ race pipe without deleting the EGR cooler?
A: Yes, the race pipe can be installed independently, but pairing it with the EGR delete provides a fully balanced airflow setup and ensures proper tuning compatibility across the board.
Q: What is the main reason to delete the EGR system on a diesel?
A: Deleting the EGR stops exhaust soot from being recirculated into the intake system, which reduces carbon buildup in the manifold and intake tract. It also eliminates common EGR failure risks like cracked coolers, internal coolant leaks, and sticking EGR valves.
Q: Can a leaking factory EGR cooler actually damage my engine?
A: Yes. A cracked EGR cooler allows pressurized coolant to seep into the exhaust or intake system. The symptoms — coolant loss, white exhaust smoke, overheating — can escalate into hydro-lock or warped cylinder heads if not addressed immediately.
