FITMENT
- 2013–2018 6.7L Dodge Ram Cummins 2500 & 3500 Pickup Turbo Diesel.
- Note: Does NOT fit Cab & Chassis (3500 / 4500 / 5500 C&C) models.
DESCRIPTION
Product Overview
- Stock emissions hardware on 6.7L Cummins diesels creates severe fluid-dynamic bottlenecks and ongoing internal contamination. The factory DPF and catalytic converter choke off exhaust gas velocity while forcing high-heat regeneration cycles, while the EGR and throttle valve assembly continuously pumps abrasive carbon soot back into the air charge—creating heavy intake sludge and thermal stress.
- Purpose-built to uncork your engine's breathing paths, this Cummins Performance Upgrade Package combines a high-velocity 4" DPF/CAT race pipe, a full EGR cooler elimination, and a smooth-bore throttle valve delete tube. By removing high-pressure exhaust restrictions and eliminating intake contamination at the source, it restores maximum air density, lowers operating temperatures, and optimizes overall engine efficiency.
Key Features
- Replaces the restrictive factory DPF and catalytic converter with a 4" mandrel-bent 409 stainless steel pipe for unrestricted exhaust flow
- Eliminates the EGR cooler, crossover tube, and actuator assembly to stop soot recirculation and coolant leak risks
- Swaps the OEM throttle valve with a smooth, straight-through delete tube for unobstructed intake airflow
- Terminates active DPF regeneration cycles, stopping the fuel-wasting regen process entirely
- Bolts directly to the factory rear tailpipe section using OEM rubber hanger locations — no fabrication needed
FAQ
Q: Why does mandrel bending matter for a diesel exhaust pipe?
A: Mandrel bending keeps the pipe’s internal diameter perfectly consistent through bends, with no wrinkles or narrowing. That means exhaust gas velocity stays high, turbo spools faster, and towing EGTs run lower. Crush-bent pipes choke down at every curve and kill flow.
Q: Can I still add a CCV reroute kit later?
A: Yes. This kit works independently of crankcase ventilation mods. You can install a standalone CCV reroute or oil catch can at any time to keep oil mist off your turbo compressor and intercooler boots.
Q: Does the 4" race pipe bolt up to the stock tailpipe?
A: Yes. It’s engineered to replace the factory DPF/catalyst canister and connect directly to your existing rear tailpipe section, using the original rubber hanger mounts for a straightforward install.
Q: What’s the advantage of 409 stainless over aluminized steel?
A: 409 SS delivers the ideal combination of heat tolerance, rust resistance, and durability at a great price point. It significantly outperforms aluminized steel in longevity and is the same material grade used by major OEM manufacturers for factory diesel exhaust systems.
Q: What Seguler product adds a coolant bypass barb to this delete setup?
A: For the complete package including a billet coolant barb adapter, check out the Bypass Hose Barb & EGR Delete Kit, which bundles the EGR delete with a heavy-duty aluminum coolant fitting upgrade.
