Banks Power Monster Exhaust System

2013–2018 RAM 2500/3500 6.7L Cummins Mega Cab

Part #: 49778-B

Overview

The Banks Power Monster Exhaust System is engineered specifically for the 2013 to 2018 RAM 2500 and 3500 trucks equipped with the 6.7L Cummins engine and Mega Cab configuration. This 5-inch DPF-back exhaust system dramatically improves exhaust flow by reducing backpressure beyond the Diesel Particulate Filter (DPF), allowing your engine to breathe more freely and produce increased horsepower and torque. Designed for diesel enthusiasts seeking enhanced performance without sacrificing reliability, this exhaust system delivers a noticeable improvement in power and fuel efficiency while maintaining a refined appearance.

With its constant-diameter 5-inch mandrel-bent 409 stainless steel tubing and a choice of two distinctive large exhaust tips, the Monster Exhaust System combines aggressive styling with functional engineering. Whether you prefer the polished chrome or the matte black Cerakote SideKick tip, Banks Power ensures durability and a clean finish that resists heat discoloration.

Key Features

This Monster Exhaust System offers a range of advanced features designed to optimize your RAM 2500/3500’s performance and aesthetics:

• Constant-diameter 5" mandrel-bent 409 stainless steel tubing for maximum flow and durability
• DPF-back design that virtually eliminates backpressure after the Diesel Particulate Filter
• 60% greater flow area compared to the stock 4" exhaust outlet
• Choice of two massive 6.5" x 7.5" ob-round slash-cut exhaust tips: polished chrome or Cerakote black
• Chrome-plated stainless steel tip engineered to resist heat-induced browning
• Negative backpressure SideKick tip design to further enhance exhaust flow
• Improved horsepower and fuel economy through reduced exhaust restriction
• 1-year limited warranty from Banks Power for peace of mind

Construction & Design

The Monster Exhaust System is constructed from premium 409 stainless steel, known for its excellent corrosion resistance and strength under high temperatures. The tubing is mandrel-bent to maintain a consistent 5-inch diameter throughout the system, ensuring smooth exhaust gas flow without restrictions or turbulence. This precision engineering reduces backpressure significantly compared to the factory exhaust, which uses a smaller 4-inch outlet.

The exhaust tips are designed not only for performance but also for style and longevity. The polished chrome tip features a heat-resistant plating that prevents the common browning effect seen on lesser-quality tips, while the Cerakote black option offers a sleek, matte finish with a rolled edge for a rugged appearance. Both tip options measure a substantial 6.5" x 7.5" ob-round shape, providing a bold visual upgrade to your RAM’s rear end.

Performance & Sound

By reducing backpressure after the DPF, the Banks Monster Exhaust System allows your 6.7L Cummins engine to operate more efficiently, resulting in increased horsepower and torque output. The larger 5-inch diameter tubing and negative backpressure tip design improve exhaust scavenging, which can also contribute to better fuel economy under certain driving conditions. The system produces a deeper, more aggressive exhaust note that enhances the driving experience without being overly loud or intrusive.

Installation & Fitment

This exhaust system is designed as a direct-fit DPF-back replacement for 2013–2018 RAM 2500 and 3500 trucks with the 6.7L Cummins engine and Mega Cab configuration. Installation requires no cutting or welding, utilizing factory mounting points and hardware for a straightforward bolt-on process. Professional installation is recommended to ensure proper fitment and optimal performance, but experienced enthusiasts with basic tools can complete the upgrade in a reasonable timeframe.

What's Included
