Are you looking to give your Duramax a horsepower boost and the sound it should have from the factory? The MBRP Armor Lite Cat-Back Exhaust is built for truck owners who want a noticeable upgrade in both sound and performance. By opening the exhaust flow, this system helps your engine breathe easier, resulting in improved throttle response, lower exhaust temperatures, and a deeper, more aggressive tone. Whether you’re towing, daily driving, or just want your truck to feel more alive, this exhaust delivers a clean, no-nonsense upgrade that hits the sweet spot between performance and value. It’s one of those mods you’ll hear and feel every time you hit the throttle.

It is built from heavy-duty aluminized steel, making it a cost-effective option that still delivers solid durability and long service life. The system features aluminized steel 4-inch tubing, which maintains a consistent diameter throughout the exhaust for maximum flow and efficiency. Designed as part of MBRP’s Armor Lite series, this exhaust is engineered to handle daily use while keeping costs lower than those of stainless options. It includes precision-fit components and a bolt-on design, allowing for a straightforward installation using factory mounting points. The result is a well-built system that balances performance, durability, and affordability, perfect for truck owners who want real gains without overspending.

Nice fabric
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Taupe
These are well made. The fabric is perfect! Not thin. I was disappointed that I ordered a size that was too large. I had to return. I need to get updated body measurements before reordering.

Cute but run big
Special Size: 7" Inseam with Pockets, Size: X-Large, Color: Flamingo Pink
Color is fantastic. Very naked feeling. Runs big. I’m a size 12/14 and usually wear XL with them sometimes feeling tight. I am pear shaped - 35” waist, 47” hip and these fit but were quite loose in the waist. I might consider sizing down if I wanted to tighter. They would be very a bump-friendly non-maternity option
