Construction & Design

The aFe exhaust system is crafted from 409 stainless steel, known for its excellent resistance to rust and corrosion, ensuring durability under harsh road conditions. The 3-inch mandrel-bent tubing maintains consistent diameter throughout bends, preventing flow restrictions and preserving exhaust velocity. The straight-through muffler design minimizes exhaust turbulence, allowing gases to exit freely while producing a deep, aggressive tone.

The system’s polished 4.5-inch slash-cut tip not only enhances the visual appeal but also resists discoloration and wear. Every component is engineered for a precise fit, using factory-style hangers and clamps to simplify installation and maintain a clean undercarriage look.

Performance & Sound

On the dyno, this aFe cat-back exhaust system delivers a measurable increase of +15 horsepower and +19 lb-ft of torque compared to the stock exhaust. These gains translate into improved acceleration, better towing capability, and enhanced throttle response. The straight-through muffler produces a deep, muscular exhaust note that is aggressive without being overly loud or droning, perfectly matching the Ram 1500’s powerful 5.7L Hemi engine.

Installation & Fitment

Installation is straightforward and requires no cutting or welding. The system uses factory-style bayonet hangers and band clamps, ensuring a secure, leak-free fit that aligns perfectly with the vehicle’s existing mounting points. This design allows for a hassle-free upgrade that can typically be completed with basic hand tools.
