FITMENT
- 2013–2019 6.7L RAM Cummins 3500 Cab & Chassis.
- 2013–2019 6.7L RAM Cummins 4500 Cab & Chassis.
- 2013–2019 6.7L RAM Cummins 5500 Cab & Chassis .
- Does NOT fit regular Pickup Bed RAM 2500/3500 models due to completely different frame rail geometry, crossmembers, and pipe routing.
DESCRIPTION
Product Overview
-
Commercial 6.7L Ram Cab & Chassis trucks are built for heavy-duty use but can experience exhaust restriction, EGR contamination, and increased thermal stress from the factory emissions system. The OEM DPF/SCR assembly restricts exhaust flow and requires regeneration cycles, while the EGR system introduces soot into the intake and adds stress to factory cooling components.
- The Cummins Cab & Chassis DPF & EGR Delete Package is designed specifically for commercial chassis trucks. Featuring a 4" race pipe with Cab & Chassis-specific fitment and a heavy-duty EGR delete assembly, this kit helps improve exhaust flow, reduce intake contamination, and support more reliable heavy-duty operation.
Key Features
-
Built for Heavy Duty: Constructed with corrosion-resistant 409 SS and thick mounting flanges to withstand commercial towing and extreme work environments.
- Heavy-Duty Solid Block-Off Plates: Premium CNC-machined billet aluminum and steel plates deliver a clean, leak-free seal against factory manifold pressure.
- 4" Free-Flow DPF Delete Race Pipe: Eliminates the restrictive factory DPF/SCR canisters to drastically cut exhaust backpressure, lower EGTs, and eliminate active regeneration fuel waste.
- Commercial-Grade EGR Delete: Removes the fragile OEM EGR valve and cooler, preventing intake soot buildup and eliminating risk of internal cooler leaks.
- Cab & Chassis Specific Fitment: Precision mandrel-bent to clear commercial frame crossmembers, fuel tanks, and rear axle assemblies on 3500/4500/5500 chassis.
FAQ
Q: Why does a Cab & Chassis truck require a different kit than a standard Ram Pickup?
A: Cab & Chassis models use a different frame layout, fuel tank placement, and exhaust routing compared with standard pickup trucks. This kit is specifically designed for Cab & Chassis fitment, while pickup exhaust systems may not align correctly.
Q: Where exactly do the EGR block-off plates install on my Cummins engine?
A: They mount in two locations once the EGR cooler is removed: the exhaust block-off plate bolts directly to the rear exhaust manifold on the passenger side, while the intake block-off plate seals the intake manifold port on the driver side.
Q: Where does this delete pipe install on my exhaust system?
A: It replaces the factory DPF/SCR assembly underneath the truck, connecting directly between the stock downpipe (or front pipe) and the rear exhaust tailpipe section using the factory rubber hanger locations.
Q: Is custom ECM delete tuning required when installing this kit on a Cab & Chassis model?
A: Yes. Custom ECM tuning is required after removing factory emissions components on 6.7L Cummins Cab & Chassis trucks. Proper tuning is needed to manage engine operation and prevent diagnostic trouble codes or reduced-power modes.
