2011-2016 Duramax Banks 5" Monster Exhaust w/ SideKick Tip (4899X)

The Banks Monster Exhaust is a true 5" 409 stainless steel constant-diameter DPF-back system built specifically for 2011-2016 LML Duramax HD trucks. The negative-backpressure SideKick tip drops exhaust exit temperatures 15% during regen, cuts backpressure by 89% from the DPF and 9% at the turbine inlet, and lets the engine actually breathe — meaning more horsepower, less heat, and no more trailer meltdown.

Pick your finish: huge polished chrome SideKick tip, or Cerakote black for the murdered-out look.
