FITMENT

  • 2017-2023 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 L5P engines restricts turbine airflow, traps extreme underhood heat, and contaminates the intake manifold. The stock pressed downpipe and heavy DPF canister create severe exhaust backpressure while triggering fuel-wasting regenerations.
  • Simultaneously, the factory EGR cooler recirculates hot exhaust soot, while the CCV system dumps oily blow-by vapor into the turbo inlet—combining to form a sticky carbon sludge. Furthermore, removing factory emissions sensors leaves exposed wiring vulnerable to moisture and corrosion.

Key Features

  • Exhaust Unblock & EGT Drop: Replaces the crushed factory downpipe and DPF canister with 3.5" and 4"/5" piping to lower EGTs and stop active DPF regenerations.
  • Dual Airway Cleanliness: Completely stops abrasive exhaust soot and sticky oil mist from mixing inside the intake manifold, preserving intake airflow and protecting intercooler boots.
  • Maximum Turbo Spool Efficiency: Reduces turbine backpressure directly at the housing, enabling faster VGT spool and crisper throttle response.
  • Weatherproof Electrical Protection: Specialized CAN-BUS connector plugs ensure disconnected OEM sensor harnesses stay sealed against water, corrosion, and debris.
  • Full Performance Package: Combine your exact choice of downpipe, exhaust pipe, EGR delete, CCV filtration, and electrical CAN-BUS protection in a single order.

FAQ

Q: What components can I choose in this complete L5P master kit?

A: This modular package allows you to customize your setup with different exhaust sizes, downpipe options, EGR solutions, CCV systems, and CAN-BUS components. You can build a configuration based on your driving style, towing needs, and performance goals.

Q: Should I choose the 4" or 5" exhaust option for my L5P Duramax?

A: Choose the 4" system for easy clearance, fast turbo spool, and a smooth tone with minimal cab drone. Choose the 5" system for heavy towing, aggressive tunes, maximum EGT drops, and a deep diesel roar. 

Q: Why combine EGR and CCV upgrades together?

A: The EGR system introduces exhaust soot while the CCV system introduces oil vapor into the intake tract. Combining both upgrades helps reduce soot and oil contamination that can contribute to intake buildup.

Q: Why upgrade the turbo downpipe?

A: The factory downpipe uses restrictive bends near the turbo outlet. The upgraded 3.5" downpipe improves exhaust flow directly after the turbocharger, helping reduce restriction and improve turbo response.

Q: Why are CAN-BUS components different between model years?

A: The 2017–2023 L5P platform uses different electronic configurations across model years. CAN-BUS components are matched to specific year ranges for proper compatibility.
