2015.5-2016 Chevy GMC 6.6L Duramax LML 4" DPF & CAT Delete Race Pipe

Constructed from high-quality 409 stainless steel for superior thermal resilience and long-lasting durability in demanding environments.

Features a straight-through, 4.0-inch diameter race design—engineered without a muffler to provide maximum exhaust volume and an aggressive, raw diesel sound.

Enables the complete removal of the factory catalytic converter and DPF filter, eliminating restrictive bottlenecks for unrestricted competition flow.

Proactively prevents costly DPF-related failures and expensive engine repairs associated with modern emissions equipment.

Optimizes exhaust gas evacuation, significantly improving combustion efficiency and potentially increasing fuel economy by up to 20% under ideal conditions.

Compatibility Notice: Exclusively fits models equipped with a 3-bolt flange connection. Will NOT work for trucks equipped with a V-band clamp off the turbo direct pipe.

Designed for off-road and competition use only.

Fits: 2015.5-2016 Chevy Silverado / GMC Sierra 2500HD / 3500HD with 6.6L LML Duramax engines (Does NOT fit Cab & Chassis models).
