2015.5-2016 6.6L Duramax LML 4" DP-Back DPF delete Pipe & EGR/CCV Delete Kit

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

Features a smooth 4-inch downpipe-back exhaust system engineered with the correct 3-bolt turbo flange connection (specifically for late 2015.5–2016 LML models) to optimize exhaust flow and power output.

Utilizes an efficient venturi-style design that eliminates restrictive internal baffles to ensure an unobstructed, high-velocity exhaust path.

Significantly lowers operating exhaust gas temperatures (EGTs) and reduces backpressure to promote a healthier, more efficient engine under heavy loads.

Completely removes restrictive factory EGR and crankcase ventilation components to stop abrasive soot buildup, reduce oil deposits, and eliminate internal coolant leak risks.

Engineered precisely for 2015.5 through 2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD pickup trucks equipped with the 6.6L LML Duramax diesel engine (Requires 3-bolt flange; does not fit 2011–2015.5 V-band clamp or Cab & Chassis models).
