What Ships from This Category

• Full Delete Kits — Complete DPF, DEF, and EGR removal kits with your choice of Mini Maxx V2, EZ Lynk Auto Agent 3, or EFI Live AutoCal V3 tuner. EZ Lynk and EFI Live kits include a SOTF switch for power level switching. All include an EGR delete kit and a choice of exhaust — DPF delete pipe, 4-inch Downpipe-Back, or 5-inch exhaust system. Optional add-ons on the product page: 2-inch Up-Pipe High Flo, S&B cold air intake, and 3.5-inch downpipe – available with any kit. All kits ship with the 3-bolt flange and fit 2015.5 and 2016 GM diesel pickup trucks only.
• DPF & CAT Delete Pipe — 4-inch T409 stainless steel delete pipe with 3-bolt flange. Replaces the factory diesel particulate filter and catalytic converter section. Mandrel-bent, standalone product. Optional T409 stainless steel muffler available. Won’t fit early 2015 V-band trucks.
• LML EGR Delete Kit — Block-off plates, cooler delete hardware, gaskets, and mounting hardware. Covers 2011–2016 6.6 LML Duramax trucks — works on both V-band and 3-bolt flange vehicles.
• DPF Delete Tuners — Mini Maxx V2 is a Plug & Play tuner with OBD-II connection and power levels at Stock, +50HP, +100HP, and +150HP. EZ Lynk Auto Agent 3 handles ECM calibration through a smartphone app with power levels from 0 to +150HP, ships with a SOTF switch for physical power level switching. EFI Live AutoCal V3 is the third option for custom LML DPF delete tuning, also with a SOTF switch included. All three flash through OBD-II and strip DPF, DEF, and EGR logic for improved horsepower and torque.
• Exhaust Systems — 4-inch and 5-inch T409 stainless steel exhaust systems with 3-bolt flange for 2015.5–2016. Both available as straight race pipe or with muffler and hanger hardware included. The 4-inch is a Downpipe-Back system. Polished stainless steel Black Bandit exhaust tip available separately.
• Performance Accessories — S&B cold air intake for improved airflow and efficiency on the LML 6.6L Duramax engine. Up-Pipe High Flo available for both driver and passenger side. FASS Titanium Signature fuel pump protects the CP4.2 injection system from water contamination — a known engine reliability concern on this platform. Both work as standalone upgrades with or without a full LML delete kit. We recommend having a mechanic remove the factory components if you’re not comfortable with exhaust work.

Key Features and Benefits of the LML Duramax Delete Kit

• No more forced regen cycles or DEF heater failures
• Cleaner intake manifold without EGR soot recirculation
• Lower CP4.2 fuel system risk with FASS fuel pump upgrade
