Description
Product Overview
Unlock the true potential of your 2007.5-2012 Dodge Ram 2500 or 3500 with the iFJF 4-inch DPF Delete Race Pipe. This direct-fit replacement eliminates the restrictive Diesel Particulate Filter (DPF) from your 6.7L Cummins turbo diesel exhaust system, dramatically reducing backpressure, lowering exhaust gas temperatures, and improving both horsepower and fuel economy. Constructed from mandrel-bent T304 stainless steel, this race pipe is built to withstand extreme exhaust temperatures and corrosive conditions for years of reliable performance.
⚠️ OFF-ROAD / COMPETITION USE ONLY: This product is intended for off-road, racing, and competition vehicles only. Not for use on public roads or highways. Removing emissions equipment may violate federal, state, and local laws. Check regulations before installation.
Key Features
-
4-Inch Mandrel-Bent Tubing: Full 4.0-inch diameter T304 stainless steel throughout — no crush bends or diameter reductions that restrict flow.
-
Direct DPF Replacement: Bolts directly in place of the factory DPF using existing exhaust hangers and flanges — no cutting or welding required.
-
Significant Power Gains: Eliminates 3-5 psi of exhaust backpressure, unlocking 15-30+ RWHP when paired with appropriate tuning.
-
Lower EGTs: With the DPF restriction removed, exhaust gas temperatures drop 150-300°F under heavy load, protecting your turbo and engine.
-
Improved Fuel Economy: Reduced backpressure allows the engine to breathe more efficiently, typically resulting in 1-3 MPG improvement.
-
T304 Stainless Steel: Premium-grade stainless resists corrosion, rust, and thermal fatigue far better than aluminized steel alternatives.

Why Choose iFJF
iFJF Direct delivers premium diesel performance components backed by rigorous engineering standards.

Every unit undergoes QC dimensional inspection before shipping to ensure precise OEM flange alignment.
Frequently Asked Questions
Q: Will this fit my 2007.5 Ram 2500 with the 6.7L Cummins?
A: Yes, this 4-inch DPF delete race pipe is a direct bolt-on replacement for 2007.5-2012 Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins turbo diesel engine.
Q: Do I need a tuner with this DPF delete pipe?
A: Yes. Removing the DPF will trigger DPF-related diagnostic trouble codes and potentially put the truck into limp mode without proper ECM tuning. A compatible tuner or custom tune with DPF delete capability is required.
Q: Will this improve my fuel economy?
A: Most customers report 1-3 MPG improvement after DPF removal, as the engine no longer wastes fuel on active regeneration cycles and exhaust backpressure is significantly reduced.
Q: Is this a complete exhaust system?
A: This is a DPF delete race pipe only — it replaces the factory DPF section. It connects to the factory downpipe on one end and your existing exhaust system (or aftermarket exhaust) on the other.
Q: Do I need to weld anything?
A: No welding required. This pipe utilizes factory-style flanged connections and exhaust hangers for a true bolt-on installation.
Q: Is this legal for highway use?
A: No. This product is for OFF-ROAD / COMPETITION USE ONLY. Tampering with emissions control systems is prohibited by the Clean Air Act. Not legal for street use in any state.
