This generation sits at the intersection of older bulletproof engineering and newer emission tech—which means you've got real options to reclaim power and reliability. ### Why LMM Delete Kits Matter The LMM introduced DPF systems that clog, regen cycles that steal fuel economy, and EGR coolers known for failure. A DPF delete removes the filter entirely and requires a tuner (like the H&S Performance Mini Maxx or EFI Live Autocal V3) to disable the warning lights and recalibrate your fuel maps. An EGR delete eliminates the recirculation system and its problem-prone cooler. Many guys do both. ### What's in Stock for Your LMM We carry complete exhaust delete kits—4" downpipe-back systems that flow like they should—plus standalone up-pipes, gasket sets, and tuning platforms. The H&S Mini Maxx and EFI Live Autocal V3 are the go-to tuners for LMM trucks, offering DPF and DSP5 delete profiles. If you're building a full delete package, grab an EGR delete kit with up-pipe and intake tube to handle both emissions systems at once. ### How to Choose Your Setup **Budget route:** Start with a DPF delete tune (Mini Maxx or EFI Live). You'll see fuel economy gains and eliminate regens. **Complete solution:** Pair a full exhaust delete with DPF tuning and an EGR delete. This addresses every factory restriction. **Turbo and intake upgrades:** Stack your delete with parts from our intake and turbo
