Monster Exhaust System 5-inch Single Exit Chrome Tip 20-22 Chevy/GMC 2500/3500 Duramax 6.6L L5P Banks Power

Banks Power introduces the new 5-inch Monster Exhaust designed specifically for the 2020-2022 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 percent greater flow area than stock. The Monster Exhaust boasts 85 percent 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 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 to20 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.
