All-In-One DPF/DEF/EGR/CCV Delete Kit | 2017-2024 GM 6.6L Duramax L5P

Unleash the ultimate potential and long-term reliability of your 2017–2023 GM 6.6L Duramax L5P with the SPELAB All-In-One Complete Emissions Delete Suite. This comprehensive bundle eliminates all restrictive factory emissions equipment—including the DPF, DEF, EGR system, and CCV (Crankcase Ventilation) filter. By bypassing clogged particulate traps, fluid injection failures, and oil-soot intake buildup, this system dramatically reduces exhaust backpressure, lowers EGTs, prevents oil-fouled intercoolers, and maximizes overall engine efficiency for severe off-road and race applications.

Key Features

• Total Emissions Elimination: Combines DPF, DEF, EGR, and CCV deletes into a single all-in-one package to completely eradicate factory choking points.
• CCV System Bypass: Reroutes crankcase blow-by vapors to prevent oily sludge and carbon buildup from coating your turbocharger and intake manifold.
• Maximum Exhaust Flow: Replaces restrictive aftertreatment components with high-flow mandrel-bent piping to optimize exhaust scavenging and turbo spool-up.
• Total EGR & DEF Removal: Stops failure-prone exhaust gas recirculation and eliminates fluid-dependent regeneration cycles, ending endless dashboard warnings.
• Enhanced Thermal Performance: Significantly lowers Exhaust Gas Temperatures (EGTs) under heavy towing and high-load driving conditions.
