Product details

Product Overview

  • This 5" DPF Delete Pipe replaces the restrictive factory DPF exhaust section on L5P 6.6L Duramax diesel trucks.
  • It removes exhaust backpressure that limits airflow and power output on tuned off-road Duramax builds.
  • Mandrel-bent 409 stainless steel tubing maintains a full 5-inch diameter through every bend.
  • CNC machined flanges and MIG welds create tight, leak-free exhaust joints for reliable off-road operation.
  • This complete pipe kit includes all pipes, clamps and mounting hardware for a bolt-on style install.

Ideal For

  • Towing and Hauling: Lower exhaust backpressure helps reduce exhaust heat during heavy off-road hauling and pulling loads.
  • Daily Driving (Off-Road Only): Improves exhaust evacuation for a smoother running tuned Duramax engine off public roads.
  • Off-Road Use: Built for trail, race and closed-course diesel truck builds where full exhaust flow is critical.
  • Commercial Vehicles: Designed for off-road work trucks used on private property and closed job sites only.
  • Engine Performance Upgrades: Pairs perfectly with off-road tuners to unlock the full power potential of your L5P Duramax.
  • Long-Term Vehicle Ownership: Reduces heat buildup linked to factory DPF clogging and related service headaches for off-road rigs.

Core Advantages

  • Increased Horsepower and Torque: Reduced exhaust backpressure lets your tuned L5P Duramax make more usable power and torque across the RPM range.
  • Improved Fuel Efficiency: Better exhaust flow helps the engine breathe easier, supporting better fuel economy under off-road load conditions.
  • Reduced Engine Temperature: Faster exhaust gas evacuation lowers EGT, a key benefit during heavy pulling and sustained throttle use.
  • Extended Engine Life: Lower heat and less backpressure reduce stress on turbo, valves and cylinder components for your off-road build.
  • Direct Bolt-On Installation: Matches factory hanger points; most trucks install without cutting or welding, long bed units may need minor modification.
  • All-In-One Kit: Comes with all required pipes, clamps and mounting hardware so you do not need to source extra exhaust parts separately.

Troubleshooting and Problem Solving

Common Issues After Installation

  • Check Engine Light
  • Rough Idle
  • Reduced Power
  • Exhaust Leaks at Flanges or Clamps
  • High Exhaust Gas Temperature

Error Code Solutions

  • P2463: DPF soot accumulation - Requires off-road tuner to disable DPF monitoring
  • P2002: DPF efficiency below threshold - Requires compatible tune to turn off DPF logic
  • P242F: DPF ash restriction - Normal for delete setups, tuner required to clear code

How to Reset Check Engine Light After Installation

  1. Install a valid off-road tune for your L5P Duramax before clearing codes.
  2. Use an OBD2 scan tool to access the diagnostic trouble code menu.
  3. Select clear DTCs and confirm reset.
  4. Restart the truck and test drive to verify the light stays off.

What to Do If Your Vehicle Loses Power After Installation

  • Confirm you have loaded a correct L5P off-road tune designed for DPF delete.
  • Inspect every exhaust joint for leaks and retorque loose clamps or flanges.
  • Verify all sensors are properly reconnected and not damaged during install.
  • Check for pinched exhaust tubing that restricts flow.
  • Contact our support team if issues persist after these checks.

Long-Term Maintenance Tips

  • Regular Inspection: Every 5,000–10,000 miles, check all exhaust joints for leaks and corrosion.
  • Routine Maintenance: Wipe down stainless steel surfaces to remove road salt after winter driving.
  • Wear Parts Replacement: Replace exhaust clamps and gaskets at 30,000–40,000 miles if leaks develop.
  • Hardware Check: Every oil change, inspect and retorque flange bolts and mounting hardware.
  • Storage Tips: Clean and dry the pipe thoroughly before long-term off-season storage to prevent surface rust.
  • Warranty Reminder: "Following these maintenance guidelines will keep your 1 Year Limited Warranty valid"
