Allows the engine to exhale and breathe more efficiently and redirects hot exhaust gas to the side. Prevents trailer meltdown with 15% lower temps behind the tip. Includes huge chrome or Cerakote Black obround SideKick tip.

Specifications

Banks Power introduces the new 5-inch Monster Exhaust designed specifically for the 2020-2023 GM 6.6L Duramax L5P 3500 HD DRW 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 Cerakote matte black. And, unlike other brands, Banks' Cerakote black 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.

Banks patented negative back-pressure tip virtually eliminates back-pressure after the DPF.
With a rocket nozzle-like tip, exhaust gasses are literally sucked out of the end of the exhaust, reducing back pressure all the back up to the turbo inlet.
