TruckTok 2020-2023 6.6L Duramax L5P 5" DPF Delete pipe & 3.5" Downpipe w/EGR Delete kit

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: 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 the main advantage of choosing this 5" kit over the 4" version?

A: The 5" DPF delete pipe provides maximum exhaust flow and volume. It is ideal for aggressive tuning, heavy towing, and customers seeking lower EGTs with a deeper diesel exhaust tone.

Q: What performance benefits come from combining the 3.5" Downpipe with the 5" DPF Delete Pipe?

A: Removing the factory EGR cooler prevents exhaust soot from entering the intake, reducing carbon buildup, lowering intake temperatures, and helping prevent coolant leaks caused by EGR cooler failures.

Q: Does this kit help reduce exhaust temperatures?

A: Improved exhaust flow can help reduce exhaust restriction and support lower operating temperatures under heavy loads.

Q: How does the EGR delete protect the Duramax L5P engine?

A: Removing the factory EGR cooler helps prevent exhaust soot from entering the intake manifold, reducing carbon buildup and helping maintain cleaner airflow.
