FITMENT
- 2007.5–2009 6.7L Dodge Ram Cummins 2500 / 3500 Turbo Diesel.
DESCRIPTION
Product Overview
- Restrictive factory emissions hardware creates severe backpressure and continuous intake contamination on 6.7L Cummins trucks. Trapped exhaust heat and frequent regen cycles waste fuel and drive up EGTs under heavy load, while stock EGR hardware continuously feeds dirty soot back into the intake system.
- This complete 6.7L Cummins Performance Package eliminates every primary OEM airflow restriction in a single upgrade. Combining a heavy-duty 4-inch exhaust race pipe with an EGR and throttle valve delete, it stops intake carbon buildup, drops under-hood temperatures, and restores the uninhibited airflow needed to unlock your engine's true torque potential.
Key Features
- Replace the factory DPF and catalytic converter with a 4" straight-through race pipe for maximum exhaust flow and reduced backpressure
- Delete the EGR cooler and valve assembly to stop soot buildup, intake contamination, and common EGR failure points
- Remove the restrictive factory throttle valve with a high-flow delete tube for improved intake airflow and throttle response
- Eliminate DPF regeneration cycles, cutting wasted fuel and reducing unnecessary heat cycling
- T-409 stainless steel and aluminum alloy construction with pressure-tested TIG welds for leak-free durability
FAQ
Q: What performance gains should I expect after installing this 6.7L Cummins kit?
A: You’ll get noticeably faster turbo spool, significantly lower EGTs when towing, complete elimination of fuel-wasting DPF regeneration, and a clean intake tract free of soot contamination. It addresses both intake and exhaust restrictions simultaneously.
Q: Do I need to cut my factory exhaust to install the 4" race pipe?
A: No cutting required. The 4" race pipe is designed to bolt directly in place of the factory DPF and catalytic converter sections, using your truck’s stock mounting points and clamp connections.
Q: Why is the throttle valve delete important for the early 6.7L?
A: The factory throttle valve is a major airflow choke point, designed primarily to force EGR gases into the engine. Swapping it for a straight delete tube removes this bottleneck and maximizes intake CFM for sharper throttle response.
Q: Will the 4" race pipe create excessive cabin drone on the highway?
A: It will increase exhaust volume — that’s part of the point. You’ll get a deep, aggressive diesel tone. Cabin drone is mild with the 4" pipe unless you pair it with a full straight-pipe setup from front to back.
