Description
Enhance the performance, sound, and appearance of your 2020+ Chevrolet Silverado or GMC Sierra 2500HD/3500HD equipped with the 6.6L Duramax L5P diesel engine with the MBRP Pro Series 4-Inch Cat-Back Exhaust System. Designed for maximum durability and performance, this premium cat-back exhaust system improves exhaust flow, reduces backpressure, and delivers a deep, aggressive diesel exhaust note while maintaining a clean, factory-style fit.
The MBRP S6043BLK features 4-inch mandrel-bent tubing that maintains a consistent diameter throughout the exhaust system, allowing exhaust gases to flow more efficiently. Improved exhaust flow helps enhance turbocharger response, optimize engine performance, and reduce exhaust gas temperatures (EGTs), making it an ideal upgrade for towing, hauling, and everyday driving.
Built as part of the MBRP Armor BLK Series, this exhaust system is constructed from T409 stainless steel and finished with a durable high-temperature black coating for superior corrosion resistance and a stealth-inspired appearance. The black-coated finish offers excellent protection against road debris, moisture, and harsh weather while complementing modern truck styling.
The single side exit configuration is paired with a premium black-coated exhaust tip, giving your truck an aggressive factory-plus appearance. Designed as a direct bolt-on system, it installs using factory mounting locations and includes all required clamps and hardware for a quick, hassle-free installation with no welding required.
Whether your truck is used for work, towing, off-road adventures, or daily driving, the MBRP Pro Series Cat-Back Exhaust System delivers outstanding performance, premium durability, and a bold exhaust tone built to last.
