FITMENT
- 2013–2018 6.7L Dodge Ram Cummins 2500 & 3500 Pickup Turbo Diesel.
- This kit is designed for standard leaf-spring pickup truck configurations.
- Does NOT fit trucks equipped with the factory-optional Rear Air Suspension or commercial Cab & Chassis (4500/5500) models.
DESCRIPTION
Product Overview
- Stock 6.7L Cummins engines face heavy breathing restrictions caused by factory emissions plumbing and choked exhaust pathways. The restrictive OEM downpipe, catalytic converter, and DPF assembly generate high backpressure that traps exhaust heat, while the stock EGR loop continuously dumps carbon soot into the intake and the throttle valve creates severe air turbulence before the manifold.
- Engineered as a total airflow overhaul, this Cummins Performance Package pairs a massive 5" turbo-back exhaust with a complete EGR and throttle valve delete assembly. By replacing restrictive factory bottlenecks with a large-bore exhaust path and uninhibited intake flow, it dramatically reduces thermal stress, optimizes turbo spoolup, and unleashes a deep, aggressive diesel exhaust tone.
Key Features
- Open maximum exhaust flow from the turbocharger directly to the tailpipe with a complete 5" turbo-back system replacing the stock downpipe, catalytic converter, and DPF
- Eliminate EGR cooler failure risk and intake soot contamination with block-off plates, coolant bypass hardware, and billet standpipe adapter
- Drop towing EGTs and accelerate turbo spool by evacuating hot exhaust gases through a full-diameter unrestricted exhaust path
- Remove the need for regular DPF cleaning, replacement, and active regeneration fuel consumption — permanently
FAQ
Q: What’s the difference between a 4" DPF-back race pipe and this 5" turbo-back system?
A: A race pipe only replaces the factory DPF section while retaining the restrictive stock downpipe. The 5" turbo-back system replaces the entire exhaust path from the turbocharger housing to the tailpipe — including the downpipe — for substantially higher airflow capacity and a much deeper exhaust tone.
Q: Will the 5" downpipe clear my transmission crossmember and frame without interference?
A: Yes. This system uses precision mandrel bends engineered specifically for 2013-2018 Ram pickup chassis layout. When properly aligned during installation, the piping clears the transmission crossmember and frame rails without contact.
Q: Is installing the turbo downpipe harder than a standard DPF race pipe install?
A: Yes, it is slightly more involved. A race pipe only replaces the mid-section under the truck, whereas installing the turbo-back downpipe requires accessing and removing the factory downpipe directly from the turbocharger exhaust housing in the confined engine bay. It’s doable with basic hand tools and patience.
Q:
Can I use an off-the-shelf tuner, or do I need custom delete tuning?
A: This kit requires custom ECM delete tuning to properly manage the engine after removal of emissions components, prevent diagnostic trouble codes, and avoid limp mode. (such as EZ LYNK or Minimaxx tuner flashed with delete-capable software).
