Banks Power introduces the new 5-inch 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-inch mandrel-bent Aluminized Steel tubing and a massive patented tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown. Up The Flow With the stock exhaust nozzle measuring 2.85-inch compared to the Monster Exhausts massive 5-inch outlet, the Banks system offers a 192% greater flow area than stock. The Monster Exhaust boasts 85% less backpressure than stock, leading to more power and increased fuel economy. Change Your Look Duramax owners can choose from two huge patented 6.5 x 7.5-inch ob-round slash-cut exhaust tips: chrome-plated polished stainless steel or high-temp matte black. And, unlike other brands, Banks's chrome-plated stainless tip will not turn brown with heat. Drop That Heat The Monster Exhaust also provides a 15% 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" Aluminized Steel constant-diameter DPF-back exhaust system. 15% reduction in exhaust temperature 2 feet behind the tip during regen Huge patented 6.5" x 7.5" ob-round slash-cut exhaust tip Chrome-plated stainless tip will not turn brown with heat 85% less backpressure than stock Emissions Compliant: E.O.
