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.

I want to thank you for your time and patience. Dino diesels is truly an outstanding company. I will definitely recommend you guys when ever I can. Thanks again.

Benner

5 stars Fast shipping, quick response to my email, excellent products. Tune loaded quickly with no issues and shifting is smooth with the tow tune but I'm still experimenting. I needed a exhaust that wasn't to noisy and yours a worked perfectly and no leaks from the clamps. I did remove the 4 inches from section of straight pipe to fit my long bed crew cab but that seems to be the norm so the same pipe will fit the long bed mega cab. You were a word of mouth recommendation and I'm glad I remembered the name of your company. Thank you for helping me bring my truck back to life.

Kenneth

Yes very happy with both my orders

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

Rodrigo

Luna

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

Works as it should. Quick shipping

Chris

I wood give them 5 Stars on my order. I'am very please with my exhaust system. Thanks

Robert

Brum

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

Bryan

Aaron

Works great for me.

Jeff

McGuffin

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

I received my order quickly and it was very easily installed. I was given the wrong tunes for my vehicle but it was resolved in less than 24 hours!

Joe

Murphy

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

The service that was provided was phenomenal. Couldn't have asked for better service. Placed my order and arrived on a timely manner taken into account I live in Louisiana. Truck sounds great. Thanks again.

Josh

The best customer service in the business!!!!

Brock

Maxwell

EGR kid was a breeze, for me at least. Everything I needed was in the kit. Only thing I want to say to help for future kits, is that the gasket for the intake neck/tube, it was bent and on the verge of tearing. I was able to reuse the original one on my truck since it is a very low mileage truck. Otherwise, thank you and hope I can find something on your website I can use!

Anthony

Bran

Very pleased with it, customer service was great with any questions, only issues I had was that electrical connector plugs were not available along with a better option for switch that would of had a direct connector without splicing. Thanks

Rich

Harris

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

Kyle

Roose

good tunner worked the way they said.

Bat

I am stoked! Thank you ALL for being a part of the solution. It burns me up to know the amount of great engines out there being ruined by the ridiculous laws and science being forced on great Diesel engines. No doubt about it, there are less than a handful of un-needed factories blowing more pollution into the world than ALL of the diesel engines combined. Thank you again for all you do! God speed.

Mike

Thompson

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

Thanks for the promoptly sending my order. Everything fit great. I'm totally satisfied!! Thanks again!

Oliver

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

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

Unkel

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

If I could give you guys a 10-star review I would I've also reached out to a lot of my friends that also drive diesels and forwarding your guys's information to them so that they can purchase the delete kits also a couple of my friends have fleets of trucks so they will be in contact I appreciate you guys thanks for being awesome

Ian

Lewis

Works awesome. Thanks I appreciate you.

Don

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!

Mark

Lujan

THANK YOU!

Shane

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

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.

Don

Perfect I love it

Jose Ramos

Cortez Lopez

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.

Dave

Peevey

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.

Cordy

DD

Great feedback with issues with software. Very responsive and helpful. Great customer service for products.

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

Sun

Exhaust came in on Tuesday. Well packaged and perfect box. Got the truck completely done today. Slow day at the shop so I got it all done. I want expecting that much power honestly. What a difference. Already 3.5mpg better. Truck is a monster now. Shocked really. Sounds sick too!!!! Thank you guys for the product, communication. Perfect. It's like a new truck.

Harrison

Lansdale

This product is really great. It has significantly improved the fuel mileage, going from 23 mpg to 28 mpg. On top of that, the engine now responds much more quickly when taking off.

Dennis

My order was shipped right out and I received it quickly. I am very pleased with your service and product. 5 stars!

Chris

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

Ordering process was great and everything arrived quickly and intact. The GDP tunes seem decent although there is some smoke on level 1 where I wouldn't think there would be any. Overall very satisfied with the product.

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.

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)

Daniel

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

Everything worked out perfectly. Super happy.

Rian

Mckinnon

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

Great company to work with. I had a problem with my order and they took care of it right away. I would recommend them to all my friends.

Dave

S

Kit was great so far 5" was very tight at the down pipe had to bend it on frame side. And had to weld up the clamps that hold exhaust together they were a little chincy other than that no complaints at all.

Jeramie

Speck

Yes, I am definately happy with the products and services I purchased from you! The shipping was fast and secure, arriving within 5 days of ordering.

I would just like to say thank you for such a great system your team sold me. I had everything I needed and made this kit installation go very smoothly. I was very nervous going into this, my boys kept telling me it will be fine. The Agent 3 device was such an easy install it was crazy. Everything connected very easily and meshed well with my Banks equipment I added with it. When I have heard folks say it will wake up your truck, I had no idea until I started driving it. Completely different truck. Thank you for supporting this equipment and making this high value upgrade a smooth one. I definitely am spreading your name out there.

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.
