Construction & Design
The Scorpion Cat-Back Exhaust System is crafted from high-quality aluminized steel tubing, which offers excellent resistance to rust and corrosion while maintaining strength and durability. The 2-1/2" mandrel bends ensure consistent diameter throughout the system, minimizing turbulence and maximizing exhaust gas velocity. This design promotes efficient scavenging and helps your engine breathe better under load.
The chambered muffler is strategically sized at 18 inches to provide a deep, aggressive tone without excessive drone, making it suitable for both spirited driving and everyday use. The polished tip adds a refined finishing touch that complements the rugged styling of the Jeep Wrangler Unlimited JK.
Performance & Sound
By reducing exhaust backpressure and improving flow dynamics, the aFe Scorpion Cat-Back Exhaust System enhances engine efficiency, resulting in improved horsepower and torque output. Drivers will notice sharper throttle response and a more robust exhaust note that emphasizes the Wrangler’s naturally aspirated V6 engines. The chambered muffler design delivers a balanced sound profile—loud enough to be engaging but controlled enough to avoid fatigue during long drives.

It utilizes OE-style bayonet hangers and includes all necessary hardware, such as band clamps, to ensure a secure fit without the need for cutting or welding. Installation can typically be completed with basic hand tools and does not require modifications to the vehicle’s factory catalytic converters or emissions components.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
