2017-2023 6.6L Duramax L5P DPF/CCV/EGR All-in-One Kit

Replaces the restrictive factory pressed downpipe and heavy DPF canister with high-flow exhaust piping to dramatically drop exhaust backpressure and stop fuel-draining active regeneration cycles.

Eliminates the factory EGR cooler to stop hot exhaust soot from recirculating and mixing with intake air, completely removing internal coolant leak risks.

Incorporates a complete CCV reroute system to direct oily crankcase blow-by vapors away from your turbocharger inlet, keeping intercooler piping, boots, and turbo components clean.

Reduces turbine backpressure directly at the turbo housing to enable faster variable-geometry turbo (VGT) spool-up, crisp throttle response, and lower operating exhaust gas temperatures (EGTs).

Bundles comprehensive exhaust, EGR, and CCV modifications into a single all-in-one package to eliminate duplicate teardown labor and unblock both intake and exhaust pathways simultaneously.

Engineered precisely for 2017 through 2023 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L L5P Duramax diesel engine (Excludes commercial Cab & Chassis models).
