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

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

Engineered with smooth 4-inch mandrel-bent piping featuring the correct factory V-band clamp turbo discharge style (specifically for 2011–2015.5 LML models) to ensure rapid turbo spool-up and optimal exhaust flow.

Completely eliminates restrictive factory DPF and catalytic canisters to stop fuel-draining active regeneration cycles and significantly lower operating exhaust gas temperatures (EGTs).

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

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

Bundles comprehensive exhaust, EGR, and CCV modifications into a single service to eliminate duplicate teardown labor around the tight rear engine compartment.

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