3.0L Duramax EGR Delete Kit

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.

I pull a 48ft car hauler with my 2014 Ford 1ton, 5.9mpg and the truck would overheat. Installed the delete kit, no more overheating 12.8mpg. AWESOME THANKS

Jonathan

Thanks for selling these kits! My truck runs like a champ. It was super easy to update the SCT and flash the ECU. I was a little worried but there was good instructions!

Angel

Proven

The kit was great and super easy to install. I didn't see the transmission tune.

Ralph

Franks

The product was exactly as pictured and was what was expected. The shipping was late and I paid $350 for overnight shipping and it ended up being two days and I still had to go pick it up from the shipper (FedEx).

Tyler

Cline

Excellent customer service and the process was pretty simple overall (lots of wrenching but so worth it!). We are ecstatic with the improved performance of the truck. Tuner is excellent and easy to understand!

Dianne

Brooks

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

Very happy with my purchase great products thank you and I loved how fast it arrived thanks again

Peter

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.

Ok. We did the download from your email. TRUCK RUNS GREAT!!! THANK YOU!!!

Michael

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.

Lower RPM when cruising on the highway at 70! 1600 RPM and also a nice gain in mileage.

Brian

J

So far exactly what I want to achieve, smooth, no surging, trans is solid. The delay between the 3rd and 4th is a bit long. I was hoping for an earlier shift.

Mike

G

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

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.

Dale

Cagley

Everything I needed was in the kit I was very happy with Everything except the shift on the fly selector. I spent 2 hours installing it in a very inconspicuous location. After I installed it we could not get the proper voltage reading for it to work correctly with my truck. So now I have it still mounted in my truck but I had to unhook it so it was a $150 item that I won't be able to use. But everything else worked very well and I am pleased with the outcome of the installation. Thank you for your products. Will be purchasing more form your company in the future

Bobby

Holt

I am very pleased with my purchase!! The only thing I wish I would have got was the pyro that goes with it. I'm saving now so I can purchase that in the near future. Thank you so much!

Jose Ramos

Cortez Lopez

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.

Adam

I am very pleased with everything purchased from here. All went smooth with no installation issues. Thank you for making my truck awesome!

Gary

Morrison

My feedback on Jeep Cherokee | Ram 1500 3.0L Eco Diesel EGR DPF DEF Delete Kit: Very happy with the setup. Some issues I had was the exhaust hitting the transmission mount. The bend that it comes with was not enough so it rubs. It needed better instruction for the "Jeep" model EGR Delete. All I could find was for the Ram. The Ram is slightly different than mine is, routing back to firewall heater core hose, mine does not have that and I had to simply cap a line off. The upper had the holes drilled in wrong spots for my metal tube coolant input. I just cut your bracket and deadhead the input side from just the loose piece. Otherwise I am happy I do not have the crap egr,def,and the dpf is gone!!!

Eric W Fulton

I'm very happy with the service and the fast response when I had any questions thank you very much

Eliazar

Very helpt and really like the quick reply's to any question I had Thanks

Steve

Jones

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

Hey, it all went well the freezer did the trick (on mm3), it all went back to stock and then everything loaded on. It's awesome, I am very happy truck runs like a dream transmission is buttery soft. Very impressed. Thanks for all your help and good service ií will definitely recommend you to my friends. Thank you again

Absolutely amazing customer service and shipping. Have told several people to do business with you. Couldn't be happier. 5 stars all the way

Philip

Triplett

Great kit. Truck runs great. I went from 16.2 highway mpg to 19.9 highway mpg. The kit did not substantially increase exhaust noise, the truck is still quiet for a diesel. I am very pleased. I can now go down to grand isle fishing and not have to worry about my truck saying in 50miles your truck will only go 50 mpg. What a relief!

Steven

Jeff

Watkins

Everything went well. Took me 4 hours to complete, solo. Only gripe I could have (which I don't) would be the lack of instructions for the bracket that bolts to the exhaust. Took me a while to figure that out as the instructions showed a different set up. Preciate the kit. Have recommended to other folks.

Hats off to diesel lion. I purchased my 6.7 ford tuner approximately three weeks ago I received my tuner within three days of ordering, which was fantastic. Wasn’t expecting it for a week to a week and a half. when I received it, I opened up the box to see what came with it and noticed the gauge wasn’t in the box was planning to put it on the upcoming weekend was very disappointed at the time. I thought I was gonna have a heck of a time trying to get a hold of them and resolve the issue I first called them no answer then email them got an answer with an hour after hours. I sent them photos of what I received in the box and the person that have been talking to said he would send me one out, I thought well it’ll be another week or two before I received it. I got it within two days again very very happy with their response and concern they sent me a whole new unit very appreciative to diesel lion the way they handled it very very happy with them. Long story short if you need to order tuners or anything and need good service order from diesel lion they will take care of you. Thank you again diesel lion. If there’s anything else I need I will definitely order through them. Thanks again Cardel Howell.
