FITMENT
- 2013–2018 6.7L Ram Cummins 3500 Cab & Chassis trucks diesel engine.
DESCRIPTION
Product Overview
-
Extreme exhaust restriction and carbon soot contamination compromise the efficiency and durability of 2013–2018 Ram 3500 Cab & Chassis 6.7L Cummins work trucks. Heavy stock DPF/CAT filters trap heat and exhaust gases under the truck, while factory EGR hardware continuously feeds dirty soot back into the engine's fresh air supply.
- This complete Cab & Chassis Performance Package replaces restrictive OEM emissions components with a free-flowing 4-inch exhaust pipe and precision EGR removal plates. Designed specifically for commercial chassis layouts, it opens up exhaust flow, prevents power-robbing intake sludge, and supports a cleaner, far more reliable setup for heavy-duty commercial use.
Key Features
-
Stainless steel, aluminum alloy, and high-temperature silicone construction — pressure-tested TIG welds guaranteed leak-free for commercial-duty service life.
- 4" DPF/CAT race pipe eliminates the restrictive factory DPF and catalytic converter to dramatically lower exhaust backpressure, accelerate turbo spool, and reduce towing EGTs.
- Cab & Chassis exclusive fitment — pipe routing and bracket placement specifically designed around commercial frame rails, DEF tank positioning, and rear axle configurations.
- Stops fuel-wasting active regeneration cycles during extended idle and heavy commercial operation, cutting unnecessary fuel consumption.
FAQ
Q: What do the included metal brackets and long studs do?
A: When the bulky factory EGR cooler assembly is removed, the engine wire harness and transmission dipstick tube lose their original mounting points. The provided bracket and studs re-anchor both components in their correct positions, preventing vibration damage, rattling, and wire harness chafing against hot engine surfaces.
Q: Why can’t I use a standard Ram pickup DPF delete kit on my Cab & Chassis?
A: Commercial 3500/4500/5500 Cab & Chassis trucks have flatter frame rails, different crossmember spacing, and larger EGR manifold ports compared to pickup bed models. A standard pickup delete pipe won’t clear the frame and crossmembers, and pickup-sized EGR block-off plates won’t seal the larger Cab & Chassis exhaust manifold ports — you’ll get severe exhaust leaks.
Q: Do I need to completely remove the factory EGR cooler when installing this kit?
A: Yes. This is a complete EGR cooler delete package, not a bypass or block-off-only solution. The OEM EGR cooler assembly must be fully removed before installing the provided block-off plates, coolant re-route hose, and mounting brackets for correct fitment and sealing.
Q: Is custom ECM delete tuning required after installing this 4" delete kit?
A: Yes. Removing the DPF and EGR hardware will immediately trigger check engine lights and force the truck into reduced-power limp mode unless custom ECM delete software has been flashed before starting the engine. Professional tuning is mandatory for safe operation.
