Banks Power Monster Exhaust System 5-Inch DPF-Back Aluminized Steel for Select 2020-2022 Chevy/GMC 2500/3500 (6.6L)

Fits select 2020-2022 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks (6.6L Duramax L5P).

Relieve the heat and backpressure issues inherent to the factory L5P exhaust with the Banks Power 48997 Monster Exhaust system. This 5-inch DPF-back system is engineered with constant-diameter mandrel-bent aluminized steel tubing to maximize flow. By replacing the restrictive stock nozzle with a massive 5-inch outlet, this system provides a 192% greater flow area and reduces backpressure by up to 89% compared to the original equipment. This increased efficiency translates directly to improved power and fuel economy for your heavy-duty Duramax.

A critical safety feature of the Monster Exhaust is its patented 6.5 x 7.5-inch ob-round slash-cut tip. During the regeneration cycle, exhaust temperatures can skyrocket for up to 20 minutes. While the factory exhaust often directs this intense heat directly at a trailer, the Banks side-exit design allows ambient air to mix with and diffuse the gas, reducing exit temperatures by 15% (measured two feet behind the tip) and protecting your towed assets from heat damage. This system is compatible with trucks equipped with aftermarket airbags.
