Banks Power Monster Exhaust System

2018–2026 Jeep Wrangler Unlimited JL 2.0L

Part #: 51365

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 2.0L engine. This exhaust system replaces the restrictive factory components with a free-flowing 3-inch mandrel-bent stainless steel design, significantly improving exhaust flow and reducing backpressure. Ideal for Jeep enthusiasts seeking enhanced performance, improved ground clearance, and a more aggressive exhaust note, the Monster Exhaust delivers a strong, authoritative growl without the annoyance of highway drone.

By removing the factory 2.25-inch piping, resonators, and OEM muffler, this system not only boosts exhaust efficiency but also reduces weight and increases rear-end ground clearance. This makes it a perfect choice for off-road adventurers who demand both performance and durability from their exhaust system.

Key Features

The Banks Power Monster Exhaust System combines advanced engineering with rugged construction to deliver superior performance and sound. Key features include:

• 78% greater flow area compared to the stock exhaust system for improved exhaust gas evacuation
• Full 3.0-inch constant-diameter mandrel-bent tubing replacing factory 2.25-inch piping
• Slash-cut high tuck tip designed to enhance departure angle and protect the exhaust on rough terrain
• Free-flowing Monster-Muffler mid-mounted muffler section that reduces backpressure without sacrificing sound quality
• Strong, authoritative growl under load with minimal highway drone for comfortable cruising
• Improved rear-end ground clearance to aid in off-road maneuverability and rock crawling
• Durable 409 stainless steel construction for long-lasting corrosion resistance
• 1-year limited warranty for peace of mind

Construction & Design

Crafted from premium 409 stainless steel, the Banks Monster Exhaust System is built to withstand the rigors of off-road use and harsh environments. The mandrel-bent tubing ensures smooth, unrestricted exhaust flow by maintaining a consistent diameter throughout bends, which helps preserve exhaust gas velocity and reduces turbulence. The system’s design eliminates restrictive resonators and the factory muffler, replacing them with the high-flow Monster-Muffler that balances performance gains with a refined exhaust tone.

The slash-cut high tuck tip is engineered to improve the Jeep’s departure angle, minimizing the risk of damage during off-road excursions. This thoughtful design detail enhances both functionality and aesthetics, giving the Wrangler a more aggressive stance while protecting vital components.

Performance & Sound

The Monster Exhaust System is engineered to deliver a noticeable performance improvement by reducing backpressure and increasing exhaust flow by 78% over stock. This enhanced flow helps the engine breathe more efficiently, potentially improving throttle response and overall driving dynamics. The exhaust note is deep and aggressive under acceleration, providing an exhilarating driving experience without the intrusive drone commonly associated with aftermarket systems during highway cruising.

No cutting or welding is required, making installation straightforward for experienced DIYers or professional shops.
