Bring out the full potential of your GMC Sierra or Chevrolet Silverado LM2 3.0L Duramax with a complete delete solution from Diesel Lion. Built for drivers who want stronger performance, sharper throttle response, and a cleaner, more efficient setup, this package is designed to deliver the results your truck should have had from the factory.

Delete tuning helps unlock increased horsepower and torque, improved acceleration, and more responsive performance throughout the RPM range. The result is a truck that feels stronger, pulls harder, and responds more consistently under load.

This tuning also refines fuel delivery and engine calibration for improved overall efficiency and drivability. With optimized tuning and reduced exhaust restriction, your LM2 can run cleaner and more efficiently while maintaining the performance gains you expect.

By removing restrictive emissions components and recalibrating engine parameters, this setup improves exhaust flow and reduces backpressure. That can help support engine longevity and reduce the chance of issues caused by plugged or restrictive exhaust components.

If you want a cleaner engine bay, improved performance, and a more aggressive overall setup, this LM2 complete delete kit delivers exactly that.


3.0L Duramax EGR Delete Kit

Kit Includes

  • High-quality 4-ply silicone coolant hose (1)
  • Caps (2)
  • Ground cable (1)
  • Blocker plates for the EGR valve and cooler (2)
  • Intake plug (1)

This kit allows for 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 designed to eliminate the restrictive EGR cooler and valve, reducing the limitations caused by recirculated exhaust gases. Removing these components helps improve airflow and reduce carbon buildup for a cleaner and more efficient combustion process.

Exhaust Valve Elimination:
The exhaust valve is a common source of carbon buildup and reduced functionality over time. When combined with the race pipe, the LM2 EGR Delete Kit removes this potential restriction, helping promote smoother operation and improved reliability from critical engine components.

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

Professional installation is strongly recommended, as removal of essential engine bay components is required to extract the OEM system.


3.0L Duramax Cat and DPF Delete Pipe

Professional installation is strongly recommended, as removal of essential engine bay components is required to extract the OEM system.

Fabricated from durable 16-gauge stainless steel, this exhaust system is built for a precise fit using machined flanges and lap-joint style clamps. It is designed to improve performance, reduce exhaust gas temperatures, and increase airflow, all while giving your truck a deeper, more aggressive sound.

Uses the existing muffler.

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.

Dale

Cagley

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 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

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

Darrell

It was great so far so good 👍

Robert

Stuart

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.

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

Had my tunes and auto agent for about a month now. Super happy with results and wow was the my tuner delivered FAST, practically next day thru FedEx.

Jorge

Torres

Great!

Don

Peters

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.

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.

Five stars, very responsive!

Nelson

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

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

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

Very happy with everything 5 stars

Kelly

Jim

Jones

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

Everything was great my order was exactly what I wanted no hassle no problem. Would definitely order again from Y'all again.
