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.

Yes I'm very happy with the kit I got it in and it's working great.

Jim

Jones

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.

Did exactly what I wanted.... And would definitely recommend

Greg

Your service was awesome, I was amazed how fast my order was shipped and the customer representative was very helpful. Thanks again, Steve in Colorado

Steven

Allard

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

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

Ralph

Franks

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.

Worked great! The kit had everything I needed to fix the issue.

Tommy

Johnson

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

Just finished my tuner and I love it. I I appreciate the quick shipping and great customer service u provided. Everything fit perfectly and was easy to do. I give ya 5 stars no doubt!

Anthony Jackson

Jackson

Installation for exhaust was pretty straightforward. Internet connection is slow where I live, so download of the tune was pretty time consuming. Also had to take off my dashboard to access unlock location for ECU. On the upside, easily added 3mpg - sometimes a little better when taking it easy. Amazing to get almost 30mpg (sometimes low 30's) out of a 1/2 ton pickup truck.

Jeffrey

You guys are the best, thank you.

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

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

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

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.

Johnny

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)

Mike

Works as it should. Quick shipping

Chris

Excellent service and parts... Fast shipping!

Jonathan

I like it, the install wasn't too bad. Wish it would've came with instructions, that would make it a lot better.

Marcus

Moore

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

You guys did awesome!!!

I am extremely happy with my product I ordered. Easy installation and everything was well packaged.

Ray

Moyer

The kit was fantastic. My stage 2 tow tune is a good tune.

Jeff

Wooton

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'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.

Yes I was very happy.

Well let's just start this out by saying I have a 16 ram 6.7 and I ordered the ezlynk with the LION package shipping was very fast and everything was complete I deleted my rig it took a complete weekend because we had a little hiccup with the ezlynk not hooked to a technician but as soon as GDP opened the problem was completely fixed the five position switch was perfect and everything functions great the tip for the 5in exhaust is completely over the top but as a dump would look great I'm very pleased with the tunes just took my camper on a 80 mile journey and have ZERO complaints now the truck is a beast I highly suggest you go with DIESEL LION for the simple fact that it was very easy to install and use ...... on a side not I do also recommend headstuds!!!! Definitely worth it THANK YOU DIESELLION.COM for everything I will be sending business your way with all my friends

Casey

S

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.

Gary

Morrison

I'm so happy with the parts and I'll definitely keep buying them for you guys. Thank you.

Very pleased with everything I got everything went pretty smoothly and is working great! Thank you guys! Would definitely shop again or suggest to others. Only complaint is on the 5-in downpipe it is a rather tight fit and kind of touches the frame there maybe a slight Factory dent or something

Jude

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

John, I'm a big thumbs up on your team overall. Very pleased with the level of support prior to, during, and after the changes I made. The number one differentiator between your team and others is the ability to pretty quickly get a live person on the phone and if needed for them to remote into the laptop connected to the vehicle. There were a few issues, but quickly addressed and or your guys confirmed for me what was happening and that all was well and as expected. Good work by all! A+ so far! Thanks Chris

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!
