2020-2022 3.0L Duramax Exhaust & Fuel Package (LM2-FUE-PKG)

Note: Custom aftermarket tuning is required for the delete pipe, and it is designed for competition/race use only. Fitment is not guaranteed for new interior-style trucks. Professional installation by a certified shop is highly recommended. This package cannot ship to the US.

Three upgrades for your 2020-2022 3.0L LM2 Duramax in one package. The 3" delete pipe replaces the restrictive OEM system while keeping the factory muffler and dual exhaust, the CAT fuel filter adapter makes filter changes easier and keeps your OEM fuel heater and water-in-fuel sensor, and the billet fix kit reinforces the crack-prone plastic filler neck.

Part Number: LM2-FUE-PKG
