Banks Power 20-21 Chevy/GMC 2500/3500 6.6L Monster Sport Exhaust System

Banks Power introduces the new 5- in. Monster Exhaust designed specifically for the 2020-2021 GM 6.6L Duramax L5P 2500/3500 HD pickup trucks. The DPF-back exhaust system features constant-diameter 5- in. mandrel-bent Aluminized Steel tubing and a massive patented tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown. With the stock exhaust nozzle measuring compared to the Monster Exhausts massive outlet, the Banks system offers a 192 percent greater flow area than stock. The Monster Exhaust boasts 85 percent less backpressure than stock, leading to more power and increased fuel economy. Duramax owners can choose from two huge patented 6.5 x 7.5- in. ob-round slash-cut exhaust tips: chrome-plated polished stainless steel or high-temp matte black. And, unlike other brands, Bankss chrome-plated stainless tip will not turn brown with heat. The Monster Exhaust also provides a 15 percent reduction in exhaust temperature two feet behind the tip during regen! The Diesel Particulate Filter (DPF) on the Duramax L5P is cleaned through regeneration in which scorching exhaust gas temperatures can last up to 20 minutes while driving. Unlike the stock Duramax exhaust, which directs a prolonged jet-like blast of super-heated exhaust gas directly at anything being towed, the Monster Exhaust is aimed out to the side of the truck. This allows ambient air to diffuse the heated gas, eliminating the risk of melting a trailer, which has been reported by many Duramax owners.

The Banks Power Monster Sport Exhaust System, part number GBE48997, is engineered specifically for 2020-2021 Chevy and GMC 2500 and 3500 HD trucks equipped with the 6.6L Duramax L5P engine. This 5-inch single exit exhaust system features mandrel-bent aluminized steel tubing that ensures maximum flow and durability. Its massive patented tip, available in chrome-plated polished stainless steel or high-temperature matte black, not only enhances the truck's aesthetic but also maintains its appearance under high heat conditions. The system’s design provides a 192% greater flow area than stock exhausts, significantly reducing backpressure and increasing engine efficiency. With 85% less backpressure than the stock exhaust, owners can expect noticeable improvements in horsepower and fuel economy, making it an excellent upgrade for towing and daily driving alike. The Monster Exhaust system also reduces exhaust temperature by approximately 15% two feet behind the tip during regen cycles, helping to manage heat more effectively during DPF regeneration. Importantly, the system is directed outward to the side of the truck, diffusing hot gases and preventing potential trailer melting issues experienced by other exhaust setups. The system is designed to fit trucks with aftermarket airbags and is suitable for single rear wheel configurations. It is not compatible with 2024 model trucks and installing it on such may trigger a check engine light. This product is CARB acknowledged and Prop 65 compliant, aligning with environmental and safety standards.
