FITMENT
- 2017-2019 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 6.6L 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: high-flow piping 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: Why combine the DPF pipe, downpipe, EGR delete, and CAN Bus plug together?
A: Each component addresses a different part of the factory system. The downpipe and DPF pipe improve exhaust flow, the EGR delete helps reduce intake soot buildup, and the CAN Bus plug supports proper vehicle communication after hardware changes.
Q: What is the benefit of the 3.5" turbo downpipe?
A: The larger 3.5" mandrel-bent downpipe reduces restriction near the turbo outlet, helping improve exhaust flow and support better turbo response.
Q: How does the 4" DPF pipe improve performance?
A: The 4" DPF pipe replaces restrictive factory exhaust components with a smoother, higher-flow design, helping reduce exhaust restriction and improve overall airflow efficiency.
Q: How does the EGR delete help protect the engine?
A: The factory EGR system recirculates exhaust gases containing soot back into the intake. The EGR delete helps reduce soot contamination and keeps intake components cleaner
Q: Does this kit include a tuner?
A: No. This kit includes the hardware components only: DPF pipe, downpipe, EGR delete components, and CAN Bus plug. A compatible tuning solution may be required separately depending on the vehicle setup.
