Description
Product Overview
Replace the restrictive factory Diesel Particulate Filter on your 2007.5-2012 Dodge Ram 2500/3500 6.7L Cummins with the iFJF 4-Inch Stainless Steel DPF Race Pipe. Precision mandrel-bent from premium T304 stainless steel, this race pipe eliminates exhaust backpressure caused by the DPF substrate, unlocking noticeable horsepower gains, lower EGTs, and improved fuel economy. Designed as a direct bolt-in replacement using factory mounting points — no cutting, welding, or fabrication needed.
⚠️ OFF-ROAD / COMPETITION USE ONLY: This product is intended exclusively for off-road, racing, and competition use. Removing a DPF from an on-highway vehicle violates the Clean Air Act. Not for street use.
Key Features
-
Mandrel-Bent T304 Stainless: Full-diameter bends maintain consistent 4-inch internal flow path — no crush bends or flow restrictions.
-
Direct Bolt-On Design: Uses factory flanges and exhaust hangers for a hassle-free installation with basic hand tools — typically 1-2 hours install time.
-
Reduced Backpressure: Eliminates the 3-5 psi of exhaust restriction caused by the DPF, allowing the turbo to spool faster and the engine to breathe freely.
-
Temperature Reduction: EGTs drop 150-300°F at highway speeds and under load, reducing thermal stress on the turbocharger and exhaust valves.
-
Corrosion Resistant: T304 stainless steel construction resists rusting, pitting, and corrosion in all climates — including road salt environments.
-
Precision Flanges: CNC laser-cut flanges with proper alignment ensure leak-free connections to the factory downpipe and exhaust system.

Why Choose iFJF
iFJF Direct manufactures diesel performance components to demanding standards. Our 4-inch DPF race pipes for the 6.7L Cummins platform are built using the same mandrel-bending process used in professional racing fabrication shops. Every flange is laser-cut and jig-verified for proper alignment before welding. We don't cut corners on materials or craftsmanship — because we know you don't cut corners on your truck.
Frequently Asked Questions
Q: Will this fit my 2010 Ram 3500 dually?
A: Yes, this DPF race pipe fits all 2007.5-2012 Ram 2500 and 3500 models (including dual rear wheel configurations) with the 6.7L Cummins engine. Cab configuration (Regular, Mega, Crew) does not affect fitment.
Q: Is tuning required after installation?
A: Yes. Operating the vehicle without a DPF requires ECM tuning to prevent diagnostic trouble codes and limp mode. A DPF-compatible tuner or custom tune from a reputable tuner is mandatory.
Q: What's the difference between this and product #2?
A: Both pipes serve the same function with equivalent quality. Slight differences may exist in flange design or included hardware. Both are direct bolt-on replacements for your 6.7L Cummins.
Q: Will my truck pass emissions testing?
A: No. This product is for OFF-ROAD USE ONLY. Vehicles equipped with a DPF delete will not pass any state emissions inspection or OBD-II plug-in test.
Q: Can I install this without a lift?
A: Yes, the 4-inch DPF race pipe can typically be installed on the ground with jack stands. The DPF is located mid-chassis and is accessible with basic hand tools.
