Construction & Design:
Built from durable 409 stainless steel, the Force II exhaust system is designed to withstand harsh road conditions and resist corrosion over time. The mandrel-bent tubing ensures smooth exhaust flow by maintaining consistent diameter through bends, reducing restrictions and backpressure. The Super 50 Series muffler is engineered to deliver a refined sound profile that enhances the driving experience without overwhelming cabin noise.
The polished 4.00-inch stainless steel tip adds a sleek, aggressive look to the rear of your Jeep, complementing its rugged styling. Every component is precision-crafted to fit perfectly with factory mounting locations, ensuring a seamless integration with your vehicle’s existing exhaust system.
Performance & Sound
The Flowmaster Force II system is tuned to provide measurable performance gains, with dyno-tested improvements of up to 11 horsepower and 15 lb-ft of torque at the rear wheels. This translates to better throttle response and enhanced engine efficiency. The exhaust note is designed to be moderate—offering a sporty growl under acceleration while maintaining a subdued tone during cruising, making it suitable for both spirited driving and everyday use.
Installation & Fitment:
Installation is straightforward and user-friendly, utilizing factory mounting points and including all necessary hardware. No cutting, welding, or additional modifications are required, allowing for a direct bolt-on fit. This system is specifically designed to fit Jeep Grand Cherokee L 2021, Grand Cherokee WK 2022, and Grand Cherokee models from 2011 through 2021 equipped with the 3.6-liter engine.

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!
