Compatibility: 2010-2012 Dodge Ram Cummins 6.7L (2500/3500)

Product: 4" Turbo-Back DPF Delete Pipe

LEGAL DISCLAIMER & COMPLIANCE

OFF-ROAD USE ONLY: This high-performance component is engineered exclusively for competition, racing, or sanctioned off-road use. It does not comply with federal or local laws for highway operation. Installation on any vehicle registered for public roads is strictly prohibited. The end-user assumes all legal liability and risk associated with the installation and use of this product.

PHASE 1: DISASSEMBLY & REMOVAL

Step 1: Sensor & Injector Disconnection Carefully disconnect all EGT sensors, pressure sensors, and DEF (Diesel Exhaust Fluid) injector harnesses from the downpipe, SCR, and DPF units.

Step 2: Exhaust System Extraction

  • Unscrew the two primary flange connections and loosen the clamp at the rear exhaust tailpipe section.

  • Remove the SCR and DPF units from the chassis, then proceed to remove the factory exhaust tailpipe.

  • At the turbocharger, loosen the V-band clamp bolt and remove the clamp securing the factory downpipe.

Step 3: Hardware Retrieval Using a flat-head screwdriver, pry the clips from the three flange positions. Disconnect the lines and retain the factory clips, as they will be required for the reinstallation process.

PHASE 2: INSTALLATION & INTEGRATION

Step 4: Turbo Pipe Mounting Before fitting the pipes and mufflers, ensure that all pipe clamps are pre-positioned on the connection joints.

  • Install Pipe #1 (Turbo Pipe) using the stock turbo V-band clamp.

  • Tech Note: Snug the clamp down sufficiently to support the pipe’s weight, but leave it loose enough to allow for final alignment adjustments.

Step 5: Mid-Pipe Configuration Install the DPF replacement pipe (#3).

  • Note: For extended wheelbase models, the #2 extension pipe is required.

  • In this racing configuration, factory sensors and auxiliary lines do not need to be re-inserted into the exhaust stream. Ensure all unused harnesses are secured away from heat sources.

Step 6: Muffler Delete & Hanger Securement Install the muffler replacement pipe. Insert the exhaust hangers into the OEM rubber isolators to ensure the system is properly suspended and vibration-damped.

PHASE 3: FINAL ALIGNMENT & TORQUE

Step 7: System Validation & Securing Begin the tightening process starting from the front (turbo pipe) and working toward the rear. Align the piping with the block connections before performing the final torque.

  • Pro-Tip: For maximum structural integrity under high-vibration racing conditions, MIG welding should be applied to the slip-joint connections.

  • Warning: Do NOT weld the pipe clamps directly to the exhaust tubing.

POST-INSTALLATION ADVISORY

This hardware modification requires a compatible ECM Calibration (Tune) to disable the factory after-treatment logic. Failure to flash the appropriate software will result in the vehicle entering "Limp Mode" and triggering Diagnostic Trouble Codes (DTCs).
