| 2020-2022 | GM | Duramax LM2 Sierra/Silverado 1500 w/ 3.0L |
Note: Fitment is not guaranteed for new interior-style trucks. Custom aftermarket tuning is required. These systems require a substantial amount of work to remove the OEM components; professional installation by a certified shop is highly recommended. Designed for competition/race use only.
The DDC-3GM30 provides 2020-2022 3.0L LM2 Duramax owners the option to replace the restrictive OEM system with a free-flowing 3" delete pipe. This is a true 3" system that runs from the turbo down to the mid-pipe, allowing you to leave the factory muffler and dual exhaust intact for a clean OEM appearance while maximizing flow and performance.
