Description
Enhance the performance and sound of your 2011+ Chevrolet Silverado and GMC Sierra 2500HD/3500HD equipped with the 6.6L Duramax diesel engine with the MBRP 4-Inch Filter Back Exhaust System. Designed to improve exhaust flow while retaining the factory diesel particulate filter (DPF), this DPF-back exhaust system delivers increased efficiency, a deeper exhaust note, and dependable durability for daily driving, towing, and heavy-duty applications.
The MBRP S6032AL is manufactured from heavy-duty aluminized steel, providing excellent strength and long-lasting performance at an economical price. The corrosion-resistant construction is ideal for trucks operating in mild to moderate climates, offering reliable service without sacrificing performance.
Featuring 4-inch mandrel-bent tubing, this exhaust system minimizes exhaust restriction and maintains consistent airflow throughout the system. The larger diameter tubing helps improve turbocharger efficiency, reduces backpressure, and allows your Duramax engine to breathe more efficiently under load.
The single side exit configuration delivers a clean, factory-style appearance while producing a deeper, more aggressive diesel exhaust tone. Designed as a direct-fit replacement, the system utilizes factory mounting points and includes all necessary clamps and installation hardware for a straightforward installation.
Whether your truck is used for towing, hauling, work, or everyday driving, the MBRP Filter Back Exhaust System provides the durability, performance, and sound expected from one of the industry's leading diesel exhaust manufacturers.
