2007-2010 GM / Chevy Duramax LMM 6.6L Parts

What We Stock for This Platform

• Full Delete Kit — Complete DPF and EGR removal kit with EFI Live AutoCal V3 tuner, 4-inch or 5-inch T409 stainless steel exhaust (~2mm wall), and EGR valve and cooler delete kit. Power levels: Stock, Eco/Tow (+65HP), Street (+100HP), Max Power (+130HP). This LMM delete kit is pickup fitment only — won’t fit Cab & Chassis.
• LMM EGR Delete Kit — EGR delete plates, cooler delete hardware, gaskets, seals, clamps, and 8mm mounting hardware. Removes the factory EGR system and stops soot recirculation through the intake. Fits Silverado/Sierra 2500HD and 3500HD — this is where the LMM EGR delete kit components belong.
• DPF Delete Tuners — Mini Maxx V2 is a Plug & Play tuner with SOTF capability through OBD-II. EFI Live AutoCal V3 offers custom ECM calibration with SOTF for pickups at Stock, +65HP, +100HP, and +130HP. For Cab & Chassis with dual fuel tanks, EFI Live supports a single tune at +60HP only — single-tank C&C isn’t supported. Both handle LMM DPF delete tuning and strip DPF and EGR logic for improved horsepower and torque.
• Exhaust Systems — 4-inch and 5-inch Downpipe-Back DPF Delete exhaust systems in T409 stainless steel. The 4-inch has selectable options for with or without muffler and with or without up-pipe — a useful modification for truck owners who want a durable full-length exhaust replacement. No standalone delete pipe exists for this platform — the exhaust systems handle the DPF removal as part of the full downpipe-back run.
• Performance Accessories — S&B cold air intake for better airflow and fuel efficiency. Up-Pipe High Flo available for both driver and passenger side. FASS Titanium Signature fuel system(pump) for proper maintenance of the injection system — contaminated fuel is a known reliability concern that damages engine components on the LMM. Standalone 4-inch and 5-inch universal diesel mufflers for sound control on straight pipe setups.
