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.

Everything worked well proper planning is required because it is not perfect

I hope this helps anyone that is looking to get a kit an skeptical of the company. Parts came in 4 days. if you choose the race pipe style it is not meant to get rid of the last muffler so you will have to get a pipe from an exhaust shop to complete it. cost me 50 bucks. on the supplied hoses just purchase 5-6 feet of hose that away you have plenty of room for a clean install with no kinks (reuse the stock quick connects for the firewall). you will also want to get 5 feet of 1/4" fuel line hose for the turbo overflow line going to the nipple on the main coolant reservoir. This will allow you to get rid of the hard line section bolted to the top of the Y bridge for a clean install. The can bus plugs will work but they are not directly plug and play. The driver side frame well plug has a guide ridge in the can bus plug that you will have to use a razor blade to cut off to allow it to fit into the plug on the vehicles harness properly. The can bus plug with the latch on the driverside frame rail going to def harness you will have to shift the latch over the stops to allow it to swing and latch against the def harness plug, also watch dark iron diesels youtube video to show you how to unlock one of the pins that has to be shifted over when you get the plug. lastly the can bus plug going into the harness in the engine bay went in with no issues and worked properly. I would buy this kit again it is very affordable and works but you will just have to take a few extra steps that arent shown on any installation videos.

Okay

Everything went ok with egr delete besides the heater core hose that is supplied did not just snap on like stated had to rig factory fitting on the hose and the exhaust some of the hangers where off by a couple inches and fitment at the downpipe is not the greatest also the kit should come with new flange hardware but dose not ccv kit was perfect fit price was good

Good but needs more

The kit was easy to install but the connections for cam bus plugs had to be modified to fit with a Dremel tool.

Great customer service product could be better

Great customer service from start to finish. The exhaust brackets don't line up... the pipes are just barely long enough. Good but could be better.

Is there a muffler that fits, or can fit into the middle section. If so can you give me the length of it

TruckTok

Yes, we offer a high-flow muffler specifically designed for the middle section. It can be installed using either welding or clamping.

Does the kit come with the ecm flash/program components? Or is this just hardware?

TruckTok

This merely refers to the products shown in the picture and does not include anything related to tuning.

Why will it not fit cab chassis trucks?

TruckTok

Hey, due to variations in truck chassis structures, to ensure smooth installation and driving safety, please be sure to select a dedicated kit that perfectly matches your chassis type.
Please verify your vehicle's specific model to confirm whether it is a Cab Chassis chassis.
Structural differences may exist, so this kit will not fit cab-and-chassis trucks.
