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.

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

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.

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).

THANK YOU!

Shane

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.

Ken

Kilby

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

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

Chris

You did a great job 🤙

Oliver

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

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

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

Five stars, very responsive!

Nelson

Merced

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.

C

Gilliam

Everything was handeld very well and all the stuffed worked no problem

Chris

Shires

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

I am wicked happy with the kit I received. I was proud that I was able to do the installation.

Great product, had everything I needed. Installation went great, got it all done myself in my garage in about 6 hours. Truck runs awesome with engine and trans tunes.

Andy

Kosevich

Great!

Don

Peters

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

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

Polley

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

Brian

Jay

Thompson

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

Ray

Moyer

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

Works great for me.

Jeff

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

%100 great service awesome timing on parts!

Jesse

Ward

yes working good so far

Steve

Noriega

I love all my products and my truck runs great

George

House

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

Burns

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

19% Better MPG. Sounds like a REAL diesel. Great communication.

Worked great

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

Ralph

Franks

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

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

This kit was the best thing for my truck it like a brand new truck run so good an is bad ass fast now thanks again for great kit an service

Jeff

Watkins

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

Jim

Jones

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

Loker

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

Kyle

Roose

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

Tommy

Johnson

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

Everything worked out perfect, instruction very accurate

Willimam

Alexander

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

Travis

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

A highly recommended group of people. WIlling to help on what would normally be out of business hours. I'll be coming back for their help in the future.
