2017-2019 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.

Features 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 plugs and looped wires designed to strict factory standards to provide closed signals back to the ECM for seamless long-term operation.

Completely eliminates restrictive factory emissions equipment to stop fuel-draining active DPF regenerations and drop operating exhaust gas temperatures (EGTs).

Bypasses failure-prone factory EGR components to prevent harmful exhaust soot from choking your intake manifold and eliminate internal coolant leak risks.

Engineered precisely for 2017 through 2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD pickup trucks equipped with the 6.6L L5P Duramax diesel engine (Excludes commercial Cab & Chassis models).
