Construction & Design

The aFe Rebel Series Cat-Back Exhaust is constructed from premium 304 stainless steel tubing, known for its excellent corrosion resistance and strength. The 2-1/2" mandrel bent tubing ensures smooth exhaust flow by minimizing restrictions and turbulence, which helps optimize engine performance. The muffler is crafted from stainless steel and finished with a high-temperature metallic black powder coating to withstand harsh environments and resist rust.

The quad exhaust tips are made from black stainless steel with precision angle cuts and rolled edges, providing a refined yet aggressive look. The custom aFe logo tip brace not only adds a unique visual element but also reinforces the tips for enhanced durability. Every weld is hand MIG-welded to ensure structural integrity and a high-quality finish.

Performance & Sound

This cat-back exhaust system is designed to improve exhaust flow, resulting in increased torque and horsepower as well as enhanced throttle response. The high-flow muffler balances exhaust pulses and reduces high-pitched tones, delivering a deep, powerful exhaust note that enhances the driving experience without being overly loud or droning. The quad rear-exit design further accentuates the aggressive sound profile, making your Jeep stand out on and off the road.

Installation & Fitment

The aFe Rebel Series Cat-Back Exhaust installs using factory-style bayonet hangers, which secure the system firmly in place and maintain proper alignment under all driving conditions. Installation is straightforward and designed to be a direct bolt-on replacement for the factory exhaust on 4-door Jeep Wrangler JL models with the 3.6L V6 engine. No modifications are required; however, this system is not compatible with the factory receiver hitch (tow hitch), so removal or alternative hitch solutions may be necessary.
