FITMENT
- 2020-2023 6.6L Silverado & Sierra Duramax L5P 2500HD 3500HD Diesel engine trucks.
- Note: Will NOT fit Cab & Chassis commercial-style trucks.
DESCRIPTION
Product Overview
-
The factory emissions and exhaust systems on L5P engines present major restrictions to turbo spool and long-term reliability. The crushed factory turbo downpipe and heavy DPF canister trap extreme exhaust heat under hood, creating intense backpressure and triggering fuel-draining active regenerations.
- Meanwhile, the factory EGR cooler feeds hot, abrasive exhaust soot directly into the intake manifold, baking into sticky carbon sludge and introducing severe coolant leak risks. Additionally, removing factory sensors leaves exposed wiring harnesses vulnerable to water and debris.
Key Features
- Rapid Turbo Spool & Response: Reduces backpressure directly off the turbine housing, allowing the L5P VGT turbocharger to spool up noticeably faster.
- Stops Intake Carbon Sludge & Coolant Leaks: Completely removes the factory EGR cooler, stopping abrasive soot from choking intake valves and eliminating internal coolant loss risks.
- Weatherproof CAN-BUS Plugs: Comes with specialized connector plugs that seal disconnected factory sensor wiring harnesses, keeping moisture, dust, and corrosion out of electrical system.
- Reduces EGTs & Eliminates DPF Regens: Replaces restrictive exhaust canisters and downpipe crimps to end fuel-draining active regenerations and drastically lower EGTs.
FAQ
Q: What is included in this complete Duramax L5P upgrade kit?
A: This includes a 4" DPF delete pipe, 3.5" turbo downpipe, EGR delete kit, and CAN Bus plugs. It combines exhaust flow improvement, intake protection, and electronic compatibility components into one complete upgrade solution.
Q: How does this kit help protect the Duramax L5P engine?
A: The EGR delete helps reduce soot contamination entering the intake system, while the upgraded exhaust components improve airflow efficiency and reduce exhaust restriction under heavy loads.
Q: Why upgrade the turbo downpipe and DPF pipe at the same time?
A: The turbo downpipe improves exhaust flow immediately after the turbocharger, while the 4" DPF pipe improves flow through the rest of the exhaust system. Upgrading both sections creates a smoother exhaust path and reduces overall restriction.
Q: What is the purpose of the included CAN Bus plugs?
A: The CAN Bus plugs are designed to support communication between vehicle modules after certain factory components are removed, helping maintain proper electronic system operation for compatible applications.
Q: Does this kit include tuning?
A: No. This package includes the hardware components only. Additional tuning requirements depend on the final vehicle configuration and installed components.
