Construction & Design

The Rebel Series Exhaust System is crafted from premium 409 stainless steel tubing, known for its excellent corrosion resistance and durability under high-heat conditions. Mandrel bending ensures smooth, unrestricted exhaust flow through every curve, maximizing performance gains. Precision MIG welding guarantees strong, leak-free joints that withstand the rigors of daily driving and off-road use.

The system’s muffler is engineered to balance sound quality and performance, absorbing unwanted high-frequency tones while releasing a deep, throaty exhaust note. The dual 4" stainless steel tips are available in polished or black finishes, each featuring laser-etched aFe logos for a refined, high-quality appearance that complements the aggressive styling of your Ram.

Installation & Fitment

Installation is straightforward and designed to be a direct bolt-on upgrade using factory mounting points. The system includes OE-style bayonet hangers and heavy-duty band clamps to ensure a secure fit that resists shifting under heat and vibration. No cutting, welding, or modifications are necessary, making it an ideal upgrade for enthusiasts who want a hassle-free installation.
