Performance Overview
This complete LM2 package is designed to improve drivability and response while supporting a cleaner, freer-flowing exhaust path once restrictive emissions components are removed. Expect:
-
Stronger throttle response and acceleration
-
Noticeable power gains with 3 tunes (up to +75hp)
-
Reduced exhaust restriction for smoother flow and reduced backpressure
Results vary based on truck condition, supporting mods, fuel quality, load, and driving habits.
3.0L Duramax EGR Delete Kit (Included)
Kit Includes:
-
High-quality 4-ply silicone coolant hose (1x) and caps (2x)
-
Ground cable (1x)
-
Blocker plates for the EGR valve and cooler (2x)
-
Intake plug (1x)
This kit allows removal of the EGR cooler and valve, exhaust valve, and EGR cooler pipe.
Key benefits:
-
EGR cooler & valve removal: helps improve airflow and reduces carbon buildup for cleaner operation
-
Exhaust valve elimination: removes a common carbon buildup/failure point over time
-
EGR cooler pipe blockage: prevents unwanted recirculation of hot exhaust gases
Professional installation is strongly recommended, as essential engine bay components must be removed to extract the OEM system.
Custom 3.0L Duramax Cat & DPF Delete Pipe (Included)
A precision-fit delete pipe system built for improved exhaust flow, reduced restriction, and a deeper tone—while retaining the factory muffler.
-
Fabricated from durable 16-gauge stainless steel
-
Machined flanges for proper fitment
-
Lap-joint style clamps
-
Helps support lower EGTs and improved airflow
-
Uses the existing muffler
