The DPF (diesel particulate filter), CAT (catalytic converter), and EGR (exhaust gas recirculation) system eat into power, throttle response, and fuel economy. The parts in this collection let you reclaim what should've been yours from day one. What's the L5P Platform? The 2017-2023 Duramax L5P is GM's latest and most capable diesel engine. It's stronger, more efficient, and more tunable than the LML it replaced. That said, factory emissions equipment still chokes performance. Our delete kits and performance components are engineered specifically for the L5P's architecture—no compromises. Full Delete vs. Piece-by-Piece Upgrades If you want maximum gains, grab the GM/Chevy Duramax 6.6 L5P Full Delete Bundle . This kit removes the DPF and CAT, installs a downpipe-back exhaust, includes a CAN BUS plug kit to disable error codes, and pairs with delete software for a complete tune. Go big or don't bother. Building incrementally? Start with a downpipe. The 5" Down Pipe-Back Full Exhaust Delete drops backpressure immediately. Pair it with the S&B Cold Air Intake for breathing room at the front, then add delete software to unlock it all. Stack your mods in whatever order fits your budget.
