FITMENT
- 2013–2019 6.7L Ram 3500 / 4500 / 5500 Cab & Chassis Cummins Turbo Diesel.
- NOTE: ONLY for commercial Cab & Chassis models with straight frame rails.
- NOT fit standard Pickup trucks (with standard factory cargo beds) or trucks with factory rear air suspension.
DESCRIPTION
Product Overview
-
For 13–19 Ram Cab & Chassis workhorses, the factory DPF/SCR stack is a major liability. It is plagued by frequent P20EE codes, endless regens, and severe "derate" events that freeze truck on the job site.
- Regens only burn soot, leaving permanent metallic ash. Because commercial trucks idle heavily and pull extreme loads, filters plug much faster—forcing an out-of-pocket factory DPF replacement bill up to $4k+.
- This direct bolt-on race pipe replaces the restrictive factory DPF and CAT, engineered strictly with the unique clearance profiles required for straight-rail Cab & Chassis frames.
Key Features
- Mandrel-Bent T-409 Stainless Steel: Crafted from heavy-duty 409 SS with mandrel-bent curves to guarantee the 4" inner diameter never shrinks, maximizes flow, and resists harsh winter road salts.
-
True Cab & Chassis Fit: Custom-engineered exclusively for commercial straight-frame rails. It navigates perfectly around mid-ship fuel tanks and specialized auxiliary wiring harnesses where standard pickup pipes fail to clear.
-
EGT & Backpressure Relief: Deleting dense emissions filters drops backpressure to near-zero. Hot exhaust gases escape instantly, drastically reducing EGTs to safeguard turbocharger and head gasket under maximum GVWR towing.
- Optimized Workhorse Tone: Delivers a deep, pronounced inline-six Cummins growl and quickened turbo spool-up without creating deafening cabin noise during long-haul commercial drives.
FAQ
Q: What factory exhaust components does this Cab & Chassis delete pipe replace?
A: This is a mid-section replacement. It bolts to the rear flange of factory downpipe (under the cab) and extends to the factory tailpipe inlet over the rear axle, replacing only the restrictive DPF and CAT/SCR canisters while keeping stock downpipe and tailpipe intact.
Q: Can I install a standard Ram 2500/3500 pickup delete pipe on my Cab & Chassis truck?
A: No. Commercial Cab & Chassis trucks use a narrower, straight frame rail with entirely different fuel/DEF tank positions and hanger layouts. This kit is custom-molded strictly to clear those commercial components where pickup kits fail.
Q: Why is it highly recommended to pair this with an EGR delete kit for commercial trucks?
A: Because commercial trucks idle heavily. Intense idling forces sticky, abrasive carbon soot through the EGR valve into intake, chewing up valves and plugging the grid heater. Pairing this pipe with 14-23 C&C EGR Delete stops soot fouling and saves thousands in engine teardowns.
Q: Does this Cab & Chassis pipe delete the SCR and eliminate the need for DEF？
A: It physically replaces both the DPF and SCR canisters. Once paired with a delete tune, DEF injection system is completely deactivated, meaning no more buying fluid or dealing with urea-related fault codes and limp modes.
