3.0L Duramax EGR Delete Kit (MUST BE ADDED ON VIA MENU BUTTONS)

Kit Includes:

  • High Quality 4 Ply Silicone Coolant Hose (1x) and Caps (2x)
  • Ground Cable (1x)
  • Blocker Plates for the EGR Valve and Cooler (2x)
  • Intake Plug (1x)

This kit allows the removal of the EGR cooler and valve, exhaust valve, and EGR Cooler Pipe.

EGR Cooler and Valve Removal: 
The LM2 3.0L Duramax EGR Delete Kit is engineered to eliminate the restrictive EGR cooler and valve, liberating your engine from the limitations imposed by recirculating exhaust gases. By removing these components, you enhance airflow and prevent the build-up of carbon deposits, leading to a cleaner and more efficient combustion process.

Exhaust Valve Elimination: 
Bid farewell to the exhaust valve, a component prone to carbon buildup and reduced functionality over time. With the LM2 EGR Delete Kit combined with the race pipe, you eradicate this potential source of engine inefficiency, promoting smoother operation and prolonging the life of critical engine components.

EGR Cooler Pipe Blockage: 
The kit includes a solution for blocking the EGR Cooler Pipe, preventing the unwanted recirculation of hot exhaust gases.

*Professional installation is strongly recommended, as essential engine bay components need removal for the OEM system extraction.

FLOPRO 3.0L Duramax Cat and DPF Delete Pipe

*Professional installation is strongly recommended, as essential engine bay components need removal for the OEM system extraction.

Fabricated from durable 16-gauge aluminized steel, this exhaust system exhibits a precise fit, facilitated by machined flanges and lap joint style clamps. Unlock heightened performance, reduced exhaust gas temperatures, and improved air-flow using this system, all while indulging in its authoritative sound.

Very happy with everything 5 stars

Kelly

Hatfield

Initially hesitant about deleting, I found that it turned out to be the best thing I could have done. As a result, I no longer experience exhaust service lights, and there is no lagging when I step on the accelerator. Additionally, I have noticed an increase in fuel mileage.

I am really like y'all customers Servies Very helpful.

Could have been better on shipping notifications on tracking numbers. I had to keep on the situation of my order by constantly emailing for tracking#'s but I finally got my products and I am very happy with the end result.

You guys are the best, thank you.

Mike

thanks again the truck runs great went from 27 to 32 mpg

Darwin

I am more than happy with it. I have completed the DPF removal and straight pipen install. I have not removed the EGR. I can say that I have picked up more power and 3 more mpg towing. I have an 8k pound bumer pull camper. There is a little black smoke when I punch it; none if I drive "normal". My wife said it is louder, who asked her. I have been on the fence but your price and the extra $100 off, with free shipping was the factor. Thanks for the entire process from ordering to installation videos.

Scott

Stribling

Hello, your kit worked awesome. No issues at all. Truck runs great. Thank you

The truck is running pretty good now thanks to your tunes and email help. I ran the 60hp tune for a few days then loaded the 100hp. Ran a tranny learn session out on the interstate immediately after the flash. Truck runs better on the 100hp than the 60hp tune in my opinion. No rolling coal, just a little "coal dust" when accelerating. The mileage is fantastic compared to what it was getting before the turbo replacement and tuning. It was 13-14 mpg before the swap. Now running the 100hp tune, I'm getting 21-22mpg. Unbelievable! On a fresh refuel, I reset the mpg display on the truck. The first 125 miles saw 22.5 mpg! After five days of mixed driving, it was still holding 21.8 mpg. Now, the big question is: How accurate or valid is the PCM calculation and display? Who care? Before it was reading 13-14 m mpg. Now it's showing 21.8 mpg. That makes me happy and that a good thing. I will run a manual calculation when I refuel again in a few days to cross check. Thanks again for your help and patience.

Ken

Kilby

Very satisfied with the results of the Tow Haul tune, good service and fast shipping. I do however like talking to someone on the phone more than communication thru email. (I'm just a little old school I guess)

I'm really happy with the Ecodiesel delete kit, which comes with an ECM and transmission tune.,My first impressions are really positive.,I installed this kit last weekend and the results have been outstanding in terms of power and fuel efficiency.,My 2016 3.0L Ecodiesel was in bad shape, stuck in 'limp mode' due to an electronic throttle fault and a DPF that was completely full.,The dealer wanted to charge me over $3,000 to replace the DPF filter, but I decided to do the installation myself.,While it was a tough process, it was definitely worth the effort.,After completing the hardware installation, I cleared the engine codes and downloaded the ECM/transmission tunes.,I went for the 40hp tune, and I can really feel the difference - there's better throttle response and a 2mpg improvement on rural roads so far.,We'll have to wait and see about the long-term durability, but I'll definitely update if I run into any issues.,Overall, I'm really pleased with the product, the instructions, and the customer support.

Everything works great and the whole process was much more simple than I expected. I will definitely be recommending you to others. Thank you!

Brent

Kramer

The kit works great. The DPF and DEF deletion pipes fit perfectly. The EGR Kit had everything I needed and the RaceME Ultra was easy to install. The way the truck runs now is awesome, The horsepower and fuel mileage was exactly what I was looking for. The fuel mileage on my 2017 Dodge with the 6.7 cummins with from 15-16 MPG to 24-26 MPG on the highway and from 11-12 to 18-19 in town. I'm extremely happy with my purchase. Thank you.

Joe

Murphy

The kit was just what I needed. The only thing is there one of the hose connections that is plastic and should be metal. I swaped it out with a metal one and all is good. Thanks for shipping the kit quickly.

Chad

Tom

Fern

Very happy with my order. Could have used some instructions on the install. Thanks Youtube. Also don't really understand the trans tune. Didn't get any verification it was installed on the tuner or even how it is installed. Don't even know if I really have it.

Tracy

Funderb

Great!

Don

Peters

I just finished installing the RaceME Ultra and complete EGR, exhaust system kit. This woke my truck up like never before and it runs great. Technical support was a great help and Michael answered all my questions in a timely manner. Looking forward to many miles with no check engine lights. Thanks again for all your help.

Doug

Miller

Awesome! Install wasn't too bad on 2017 Ecodiesel Ram 1500. Truck is much more responsive and should last longer now that I am no longer spewing carbon into my intake manifold.

Daniel

Johnson

So I had a special case. I needed a tune for a 2008 C5500 Duramax. This is obviously a commercial truck. They were able to send me the handheld. My mechanic downloaded the parameters from the truck. He sent them off. I had a custom tune back in 2 days. The truck now runs great. Thanks to Dyno Diesels for a custom tune. When our government is doing everything they can to ruin diesels. Dyno has your back.

Roman

Parsons

Yes very happy with both my orders

Nicholas

Estes

Packages arrived and in good shape. When I had any questions someone would follow up with an answer. My RaceMe Ultra was easy to install and had no problem with the EGR delete kit. I did have a problem with my pipes due to the bend in the pipe that replaces the muffler. Only 2 ways I could put it. The bend up or down would not let me hook up my hanger mounts for support.

Geoffrey

Rose

Install went awesome, instructions were good and everything went smoother than expected. Thank you.

You guys did awesome!!!

Whitney

Schiesser

Product was not really compatible with the C/C as turbo is smaller so GDP will only give me 1 tune. I understand why but, I bought the 5 position switch was so I could adjust power as at times I do not tow and others 30k lbs. Other than that like the tune and GDP tech line was very, very helpful So can't use the 5 position switch but will keep until I install a larger turbo as per GDP. Thanks for the product and it really sounds like a truck now.

Bill

King

Instructions would be awesome. But overall very happy with products performance
