2011-2015.5 6.6L Duramax LML 4" DPF & CAT/CCV/EGR Delete Kit

Constructed from heavy-duty T-409 stainless steel to provide exceptional heat resistance, structural durability, and long-term protection against harsh elements.

Features a high-flow 4-inch exhaust system engineered specifically with a V-band clamp connection to allow the complete removal of both the restrictive factory catalytic converter and DPF filter.

Completely eliminates failure-prone factory EGR components to stop abrasive soot buildup, prevent clogged EGR valves, and remove internal coolant leak risks.

Incorporates a crankcase ventilation (CCV) system to vent blow-by gases, decrease oil deposits in the engine, and prevent intake gumming.

Equipped with precision O-ringed fittings where applicable, with each piece individually leak-tested to ensure a secure, reliable, and leak-free installation.

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