2004-2005 6.6L Duramax LLY 5" DP-Back DPF Race Pipe & EGR Cooler Delete Kit

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

Features a high-flow 5-inch downpipe-back race exhaust system starting right at the downpipe to allow complete removal of the restrictive factory catalytic converter and emissions components.

Designed with a clean, bung-free pipe layout to ensure a completely unobstructed exhaust flow path and maximum exhaust velocity.

Completely eliminates the factory EGR cooler to stop abrasive soot buildup, prevent clogged EGR valves, and remove internal coolant leak risks.

Equipped with pressure-tested TIG welds guaranteed not to leak under extreme thermal cycles and high-load conditions.

Engineered precisely for 2004 through 2005 Chevrolet Silverado and GMC Sierra 2500HD/3500HD pickup trucks equipped with the 6.6L LLY Duramax diesel engine (Excludes Cab & Chassis models).
