A Tough, No-Nonsense Upgrade for Your Duramax

If you’re looking to wake up the sound and performance of your 2001–2004 GM 2500 or 3500 with the 6.6L Duramax, the MBRP 5-inch Armor Plus Downpipe-Back Exhaust is a rock-solid choice. Built from corrosion-resistant T409 stainless steel, this system is made to handle the elements while delivering noticeable gains in airflow and exhaust tone. The large-diameter tubing helps the turbo breathe easier by reducing backpressure, which can lead to improved throttle response and better efficiency. Whether you’re daily driving, towing heavy loads, or just want a more aggressive tone without going over the top, this system gets the job done with a clean, no-muffler design that exits behind the passenger-side rear tire.

Built to Perform, Built to Last

Everything about this kit is designed with performance and durability in mind. The mandrel-bent tubing ensures smooth, ripple-free bends that maintain consistent diameter throughout the exhaust path. That means less restriction and more flow, especially when your Duramax is under load or working hard on long grades. The system bolts up behind the factory downpipe and includes all the hardware you’ll need, though some cutting of the OEM system may be required depending on your configuration. It’s also worth noting that this exhaust is not intended for California emissions vehicles or trucks equipped with a catalytic converter. With a bold sound, simple styling, and a 5-year warranty to back it, the Armor Plus series offers a reliable, no-compromise exhaust solution that’s ready for work or play.
