Description
Upgrade your 2009 Dodge Ram 1500 5.7L HEMI with the MBRP Armor Plus Cat-Back Dual Split Rear Exhaust System, engineered to deliver improved horsepower, torque, throttle response, and the unmistakable deep rumble of the legendary HEMI V8. Designed for drivers seeking long-lasting durability and aggressive styling, this premium cat-back exhaust offers exceptional performance while maintaining excellent everyday drivability. It features durable T409 stainless steel construction, 2.5-inch mandrel-bent tubing, and a dual split rear exit configuration for maximum exhaust flow and a refined, aggressive sound.
The MBRP S5146409 is part of the Armor Plus Series, manufactured from corrosion-resistant T409 stainless steel. This material offers excellent resistance to penetrating rust and is ideal for year-round driving, making it an outstanding value for truck owners who demand durability without the premium cost of T304 stainless steel. Backed by MBRP's Lifetime Warranty, the Armor Plus Series is built to withstand harsh road conditions while maintaining dependable performance.
Engineered with 2.5-inch mandrel-bent tubing, the system maintains a consistent internal diameter throughout every bend to reduce backpressure and maximize exhaust flow. The straight-through muffler design improves engine breathing, helping the 5.7L HEMI produce better throttle response while delivering MBRP's signature Street Profile exhaust tone—deep and powerful without excessive cabin drone.
The dual split rear exit is finished with dual polished 4-inch T304 stainless steel exhaust tips, giving your Ram a bold factory-style appearance while complementing the truck's aggressive styling. Designed as a direct bolt-on system, it utilizes factory mounting points and includes all required clamps and hardware for a straightforward installation without welding or major modifications.
Whether you're towing, daily driving, or simply looking for a more aggressive exhaust note, the MBRP Armor Plus Cat-Back Exhaust System delivers proven performance, premium craftsmanship, and long-term reliability.
