Description
Give your 2011-2015 Chevrolet Silverado or GMC Sierra 2500HD/3500HD equipped with the 6.6L Duramax LML diesel engine a bold new look and enhanced exhaust performance with the MBRP 4-Inch Filter Back Dual Outlet Single Side Exhaust System. Designed to replace the factory exhaust components behind the diesel particulate filter (DPF), this high-flow DPF-back system improves exhaust efficiency while maintaining compatibility with the factory emissions system.
The MBRP S6032409AL is manufactured from heavy-duty aluminized steel, providing an excellent balance of durability, corrosion resistance, and value. Ideal for daily drivers, tow rigs, and work trucks, the aluminized steel construction is built to withstand demanding conditions while delivering reliable long-term performance.
Engineered with 4-inch mandrel-bent tubing, this exhaust system reduces exhaust restriction and promotes smoother exhaust flow, helping improve turbocharger efficiency, reduce backpressure, and enhance overall engine performance. The dual outlet single side configuration adds an aggressive, custom appearance while producing a deeper, more refined diesel exhaust note.
Designed for a precise direct-fit installation, the system utilizes factory mounting locations and includes all required clamps and hardware, making installation straightforward without the need for major modifications.
Whether you're towing heavy loads, commuting, or upgrading your truck's appearance and sound, the MBRP Dual Outlet Filter Back Exhaust System delivers premium quality, improved performance, and an eye-catching dual-exit design.
