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.. 5-inch 409 stainless steel constant-diameter DPF-back system. Patented negative backpressure SideKick tip helps lower exhaust exit temps by 15%. Improves flow and cuts backpressure by 89% from the DPF and 9% at the turbine inlet, allowing the engine to produce more horsepower. Includes Huge Polished-Chrome Patented or Cerakote Black SideKick tip.
