Key Features:
This Flowmaster cat-back exhaust system incorporates advanced design elements to optimize performance and sound quality. Key features include:
Construction & Design:
The Force II system is crafted from premium 304 stainless steel, known for its corrosion resistance and long-lasting performance in harsh environments. The 2.50-inch mandrel-bent tubing maintains consistent diameter through bends, reducing flow restrictions and enhancing exhaust scavenging. The Super 50 Series muffler features an internal resonance chamber that effectively reduces unwanted cabin drone while delivering a deep, mild exhaust tone that complements the Jeep’s rugged character.
The exhaust tip is finished with a brushed stainless steel look that resists discoloration and adds a subtle yet refined touch to the rear bumper area. Every component is engineered for durability and designed to withstand the rigors of off-road and daily driving conditions.
Performance & Sound
This cat-back exhaust system improves exhaust flow, which can contribute to a more responsive throttle feel and a slight increase in engine efficiency. The sound profile is intentionally mild yet aggressive, providing a deep, throaty exhaust note without excessive volume or harshness. The internal resonance chamber within the muffler minimizes interior drone, ensuring a comfortable driving experience even on extended trips.

This ensures a secure fit without the need for cutting, welding, or additional modifications.

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.
