4‘’ Downpipe-Back DPF Delete Kit for 2015.5-2016 Chevy GMC LML 6.6 Duramax

4‘’ Downpipe-Back DPF Delete Kit for 2015.5-2016 Chevy GMC LML 6.6 Duramax

---tab Description---

Enhance your 2015.5–2016 Duramax 6.6L performance with this off-road/racing-only DPF-delete straight exhaust system. Designed for maximum flow and minimal backpressure, it boosts horsepower, torque, and exhaust gas temperature (ECT) reduction—ideal for towing, racing, and heavy-duty off-road use. Made from durable T409 stainless steel, it’s a must-have for serious performance builds.

Key Features

  • Full Straight-Pipe Design: Improves exhaust flow, reduces backpressure, and significantly lowers ECTs for increased engine power and efficiency.
  • Off-Road/Racing Use Only: Removes DPF and catalytic converters—not compliant with EPA/CARB emissions standards.
  • T409 Stainless Steel Construction: Offers high heat and corrosion resistance with a balance of durability and cost-effectiveness.
  • Easy Bolt-On Installation: Uses factory-style hanger locations for a secure fit without chassis modifications.
  • Performance-Optimized: Best paired with ECU tuning, larger turbos, and upgraded injectors—supports 500+ HP Duramax builds.
  • Reduced Maintenance: Eliminates DPF-related servicing and prevents clogging or failure issues.
  • Lightweight & Open Flow: No muffler or resonator for maximum sound and minimal restriction—perfect for race and off-road environments.

  • Tuner Required for Installation: Installing a LML 6.6 Duramax delete pipe requires more than just swapping out hardware. When removing of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting.

⚠ Note: For off-road/competition use only. Not compatible with emissions sensors or Cab & Chassis models. Does not include a tip. Tuning required for optimal performance.
