Overview

The Banks Power Monster Exhaust System is a high-performance upgrade designed specifically for the 2018 to 2026 Jeep Wrangler Unlimited JL equipped with the 3.6L engine. This 2.5-inch mandrel-bent stainless steel exhaust system replaces the restrictive factory resonators and OEM muffler to significantly improve exhaust flow and reduce weight.

Construction & Design

Crafted from high-quality stainless steel, the Banks Monster Exhaust System is built to resist corrosion and withstand the rigors of off-road use. The mandrel-bent tubing ensures smooth bends that maintain consistent diameter throughout the system, minimizing turbulence and maximizing exhaust flow. The integrated slash-cut tip is strategically angled downward to protect the exhaust from damage while improving ground clearance, a critical feature for off-road enthusiasts navigating rocky trails and obstacles.

The design eliminates the factory resonators and restrictive muffler, which are known to impede exhaust flow and add unnecessary weight. This streamlined construction not only reduces backpressure but also contributes to the system’s significant weight savings compared to stock.

Performance & Sound

The Monster Exhaust System enhances engine performance by improving exhaust scavenging and reducing backpressure, allowing the 3.6L V6 engine to breathe more freely. This results in a more responsive throttle and improved overall efficiency. The system’s unique muffler design produces a deep, aggressive growl that intensifies under load, delivering an exhilarating driving experience without the intrusive drone that can fatigue drivers during long highway cruises.

Designed as a direct bolt-on replacement for the factory exhaust, the Banks Monster Exhaust System installs easily on the 2018–2026 Jeep Wrangler Unlimited JL 3.6L without the need for cutting or welding. The system is engineered to fit precisely with existing mounting points and hardware, ensuring a straightforward installation process that can typically be completed with basic hand tools. No modifications to the vehicle’s chassis or suspension are required.
