The Banks Power 20-21 Chevy/GMC 2500/3500 6.6L Monster Sport Exhaust System is a high-performance exhaust upgrade designed specifically for the 2020-2021 GM Duramax L5P 6.6L diesel trucks. Constructed with mandrel-bent 5-inch aluminized steel tubing, this system maximizes exhaust flow and reduces backpressure, resulting in improved engine efficiency and power output. Its massive patented tip not only enhances the truck’s aggressive appearance but also virtually eliminates backpressure after the diesel particulate filter (DPF), helping to prevent trailer meltdown and maintain optimal exhaust flow. The system's design ensures increased airflow—up to 192 percent greater than stock—delivering enhanced performance, sound, and durability for demanding applications.
This exhaust system is a direct bolt-on upgrade for 2020-2021 GM 2500 and 3500 HD trucks equipped with the Duramax L5P engine. It is suitable for use on street and off-road vehicles, providing a significant performance boost while maintaining compatibility with existing emissions systems. Installation involves replacing the factory DPF-back section with the Banks Monster Exhaust, offering a straightforward upgrade process. The kit includes all necessary components for a complete installation, making it ideal for owners seeking increased horsepower, torque, and a more aggressive exhaust note for daily driving or towing applications.
