The Banks Monster 5" DPF-back exhaust is engineered for 2020–2021 Chevy/GMC 2500/3500 trucks with the 6.6L Duramax L5P engine. This constant-diameter 409 stainless system reduces backpressure dramatically and uses a SideKick tip to lower exhaust exit temperatures during regen. It offers massive outlet flow, side-exit tip options in polished chrome or Cerakote black, and is designed to prevent trailer overheating while improving post-DPF flow characteristics.
