5 inch 409 stainless steel constant-diameter DPF-back system with negative backpressure SideKick tip. 85 percent less backpressure and 15 percent lower exhaust exit temps than stock, allowing the engine to produce more horsepower. Improves flow and cuts backpressure. Includes Huge Polished Chrome SideKick tip.

Banks Power introduces the new 5 inch Monster Exhaust designed specifically for the 2017-2019 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 tip which virtually eliminates backpressure after the DPF and prevents trailer meltdown.

With the stock exhaust nozzle measuring 2.85 inch compared to the Monster Exhaust's massive 5 inch outlet, the Banks system offers a 192 percent greater flow area than stock. And, the Monster Exhaust boasts 85 percent less backpressure than stock, leading to more power and increased fuel economy.

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.

Duramax owners can choose from two huge 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 chrome-plated stainless tip will not turn brown with heat.

The Banks 5 inch Monster Exhaust (Part No. 48996 for chrome or 48996-B for black) fits all regular cab short bed, double cab short bed, double cab long bed, crew cab short bed, crew cab long bed, and dually models.
