2020-2023 6.6L Duramax L5P 4" DPF Delete pipe & 3.5" Downpipe w/EGR Delete kit

Constructed from heavy-duty T-409 stainless steel to provide exceptional heat resistance, structural durability, and reliable protection against rust and corrosion.

Includes a high-flow 3.5-inch turbo downpipe and a 4-inch DPF delete exhaust system engineered to significantly reduce backpressure and enhance overall engine performance.

Incorporates specialized looped wires and sensor management provisions to provide closed signals back to the ECM and maintain normal ECU operation for fuel tank and lift pump data.

Allows factory electronic modules to remain plugged into the wiring harness and securely zip-tied up to keep the CAN-BUS network fully active.

Completely removes the failure-prone factory EGR cooler and restrictive emissions equipment to stop active DPF regenerations and drop exhaust gas temperatures (EGTs).

Engineered precisely for 2020 through 2023 Chevrolet Silverado and GMC Sierra 2500HD/3500HD pickup trucks equipped with the 6.6L L5P Duramax diesel engine (Excludes commercial Cab & Chassis models).
