This package pairs Black Label RTD custom tuning with the core off-road hardware your 2024–2026 Duramax L5P needs to get everything lined up—without buying a full exhaust system.
It’s built around the essential L5P hardware stack: EGR hardware with a 3.5" downpipe, plus the DPF/CAT pipe so your setup matches your tuning cleanly and you’re not piecing parts together after checkout.
