Made for off-road 2017-2025 L5P Duramax owners, this 4/5-inch DPF delete race pipe reduces exhaust restriction and supports tuned builds needing stronger flow and serviceability.
Note: Spelab 6.6L Duramax L5P DP-Back must be used together with our downpipe. The factory downpipe has an integrated SCR assembly and cannot connect directly. Ours must be installed first to allow proper attachment of the subsequent exhaust section.
Unlock your 2017-2024 L5P 6.6L Duramax's true potential with this high-performance DPF delete pipe. Our precision-engineered solution eliminates restrictive factory filters, dramatically reducing exhaust gas temperatures (EGTs) while improving turbo spool-up and throttle response. The mandrel-bent construction ensures maximum flow efficiency, helping your diesel breathe easier. Perfect for off-road enthusiasts seeking better power delivery and reduced maintenance hassles.
