TruckTok 2017-2023 6.6L Duramax L5P DPF/CCV/EGR All-in-One Kit

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.

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.
• Fully Modular Performance Package: Combine your exact choice of downpipe, race exhaust, EGR delete and CCV filtration in a single order.

FAQ

Q: Does this kit require tuning after installation?

A: Yes. After installing this kit, custom tuning is required to properly recalibrate the vehicle's ECM and ensure compatibility with the removed factory emission components. A compatible tuner is needed to clear related fault codes and optimize engine performance.

Q: Does this kit include everything needed for installation?

A: The kit includes the main hardware needed for the DPF, EGR cooler, and CCV system modifications. Additional components such as tuning equipment or CAN bus plugs may be required depending on your vehicle setup.

Q: What are the benefits of installing this DPF/EGR/CCV kit?

A: By removing restrictive factory emissions components, this kit improves airflow, lowers exhaust restriction, and keeps your intake clean. Combined with proper tuning, it enhances turbo response and overall diesel performance.

Q: Does this kit improve turbo spool-up?

A: Yes. By reducing exhaust backpressure and improving exhaust flow, this kit helps the turbocharger operate more efficiently, which may improve throttle response and turbo spool characteristics.
