Product Description

The MBRP S6050PLM is a 4in filter-back exhaust system built for the 2011-2015 Chevrolet Silverado and GMC Sierra 2500HD/3500HD with the 6.6L Duramax LML engine. Restrictive factory exhausts on the LML create backpressure that limits turbo efficiency and reduces low-end torque, dulling throttle response - especially noticeable when towing or hauling.

As part of MBRP's PLM Series, this system uses a muffler-delete pipe design in place of the factory muffler, maximizing exhaust flow and sound. It's built from heavy-gauge aluminized steel with fully sealed, mandrel-bent tubing, and includes a CARB-approved downpipe, ensuring consistent airflow and linear power delivery while replacing the restrictive factory system.

Because this is a muffler-delete system, it does not include a muffler - buyers who want one should plan for a separate purchase. Backed by MBRP's 1-year warranty, the S6050PLM is a solid choice for 2011-2015 Duramax LML owners who want stronger torque, quicker turbo spool, and a deeper daily-driver exhaust tone.
