Product Description

The Delete.Autos 4" Downpipe-Back Race Pipe is the definitive exhaust upgrade for the 2020-2022 GM 6.6L Duramax L5P. The massive factory DPF (Diesel Particulate Filter) and SCR (Selective Catalytic Reduction) systems severely choke exhaust flow, robbing your truck of power and drastically increasing exhaust gas temperatures. This 4-inch pipe removes those bottlenecks entirely.

Race Pipe Benefits

  • Unrestricted Flow: Smooth 4-inch mandrel bends from the downpipe all the way back ensure exhaust exits as quickly as possible.
  • Stop Regens: By removing the DPF, your truck will never undergo a fuel-wasting, heat-generating regeneration cycle again.
  • The True Diesel Sound: This race pipe allows the incredible sound of the L5P V8 diesel engine to finally be heard, providing a deep, throaty exhaust note.

Vehicle Fitment

Designed to fit 2020, 2021, and 2022 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax L5P engine. Note: Custom tuning is strictly required to prevent check engine lights and limp mode after removing emissions equipment.
