Upgrade your late-model LML Duramax with this 4" DPF & CAT Delete Race Pipe, engineered for 2015.5-2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD equipped with the 6.6L LML Duramax diesel engine. Built from durable 409 stainless steel, this direct-fit race pipe improves exhaust flow while providing a precise fit for trucks equipped with the 3-bolt flange connection found on late-2015 and 2016 models.
