6.6L GM Duramax LMM (2007.5-2010)

Optimize your 2007.5-2010 Duramax LMM with performance upgrades designed for the 6.6L engine. DPFdelete provides the definitive solution with advanced DPF, DEF, and EGR delete kits, high-output race tuners, and complete exhaust systems.

Our LMM-specific components, including downpipe-back exhaust systems and precision EGR delete kits, directly address common restrictions. They are engineered to improve exhaust flow, significantly reduce carbon and soot buildup, and lower exhaust gas temperatures (EGTs). The results are measurable: increased horsepower, enhanced throttle response, greater towing capability, and extended engine life.

Built for a clear installation path, these upgrades provide a reliable power transformation for daily driving or demanding work. Ensure compliance with all local regulations. Whether you install yourself or use a professional, achieve the peace of mind that comes with a stronger, cooler-running Duramax LMM.
