FITMENT

  • 2007.5-2012 6.7L Dodge Ram 2500 / 3500.

  • Short wheelbase models (Regular Cab / Short Bed) require minor pipe trim during install.

DESCRIPTION

Product Overview

  • The early 6.7L Cummins engines suffer from heavy factory emissions restrictions. The stock DPF and catalytic converter trap intense heat, trigger frequent fuel-wasting regen cycles, and cause severe backpressure that robs your inline-6 diesel of true performance.
  • The 4" DPF Delete Race Pipe is the ultimate performance upgrade for your 6.7L Cummins. Constructed from smooth, mandrel-bent 4" T409 stainless steel, this race pipe completely eliminates the factory emissions bottlenecks. By freeing up exhaust flow, it sharply drops EGTs, restores crisp throttle response, and unlocks that deep, iconic Cummins turbo whistle and exhaust rumble.
Key Features
  • Premium T409 Stainless Steel: Mandrel-bent 4-inch T409 stainless steel tubing built to resist severe thermal stress, road salt, and long-term corrosion.
  • Eliminate Factory DPF & CAT Restrictions: Replaces the heavy, restrictive factory DPF and catalytic converter with a smooth 4-inch high-flow straight pipe.
  • Sharply Drop Towing EGTs: Accelerates exhaust gas evacuation right after the downpipe, drastically lowering Exhaust Gas Temperatures under heavy loads.
  • Kill Fuel-Wasting Regens: Permanently eliminates active regeneration cycles to improve fuel economy, restore engine efficiency, and extend oil life.
  • Direct Bolt-On Fitment: Engineered as a direct-fit mid-section replacement that mounts to stock hanger locations using heavy-duty hardware—no welding required.

FAQ

Q: Do I need a delete tuner to run this 4" DPF race pipe on my 6.7L Cummins?

A: Yes. Because removing the factory DPF deletes downstream emissions sensors, a compatible delete tuner (such as an H&S, EFI Live, or Smarty tuner) is required to clear fault codes and prevent Limp Mode.

Q: Do I need to reinstall the factory exhaust sensors into this pipe?

A: No. This is a smooth straight pipe design without sensor bungs. Once your ECU is properly tuned for a delete, you can simply unplug the factory sensor harness, zip-tie it safely out of the way, and cap or harness plug any exposed electrical connectors to keep out dirt and moisture.

Q: Will this pipe connect directly to my factory downpipe and tailpipe?

A: Yes. It is designed as a direct mid-section replacement that bolts straight to your stock turbo downpipe outlet and connects seamlessly to your OEM rear exhaust section.

Q: How much will my fuel mileage (MPG) improve after installing this pipe?

A: By eliminating power-robbing regeneration cycles that inject raw fuel into the exhaust, most 6.7L Cummins owners see an immediate improvement of 2 to 3 MPG, along with noticeably smoother throttle response.
