This video goes over the procedure to delete your DPF and install an aftermarket exhaust on your LML duramax. The truck in the video is a 2013 but it should be basically the same procedure for any 2011-2016 duramax. I also go over the steps to remove the DEF tank.
**IF THIS IS ILLEGAL IN YOUR AREA THEN DON'T DO IT UNLESS YOU JUST PLAN ON USING THE TRUCK OFF-ROAD**

Hey brother. Thank you SO MUCH for EVERYTHING!!! You’re video is literally the reason I was able to delete my 15 LML. QUESTION!!!???🚨🚨🚨🚨🚨
Do I RECONNECT the 3 clips on the top of video?!?! The FIRST thing you showed us throttle body one and 2 right after…. Or, zip tie em outta the way forever?
Your video made this so much better! Hands down best video to date! Keep em going man! You're very thorough!!!
Would love to see you do a CP3 install on the LML. All your content has been a great help. This was probably the best DEF one i have seen.
If I do a cp3 conversion I’ll film it!
Very nice and informative video! Finally someone that can make a how-to vid without constant swearing and stupid music! Well done sir!
Haha thank you!!
ive got everything in my garage and imunder the truck with an ipad watching hahahaha!
How can I contact you
@@darkirondiesel a question I have a GMC DURAMAX 2017 we fix the truck for a accident.
After fixing it, the screen tells me that the exaust fluid , I have a few miles to run.
many people say I need to change everything and delete .
but my question is can the computer be reprogrammed? Because the accident was not a big deal, that appeared to me because in the shop where they fixed it, maybe they moved it without adding liquid fluid
I hope u can help me thanks a lot 👍
Got a 2011 lml and run efi live. Runs great and no problems whatsoever. The sound of the straight pipe never gets old.
straight pipe?
@@armandocastaneda5898 Straight Pipe means No exhaust, No catalytic converter, No DEF injection. just a free flowing pipe from the down pipe (engine) back to the end of the pipe.
Thank you for the video! One tip for anyone who doesn’t want to remove the def tank is to make sure you unplug the big harness or it will continue to spout def fluid onto the ground…the mini maxx tune worked great
Did the mini max tune need to be programmed by a shop??
Just found you on RUclips not long ago. Got 2015 srw 3500 lml duramax. You good sir have some of the best videos I can understand. Getting ready to do some work on it from this video, and I feel like I should send you a paycheck check for the free info. Keep it up bud its greatly appreciated.
Haha thanks buddy! If you want you can order some stuff from darkirondiesel.com but don’t feel obligated at all
I'll order something soon. Keep up the good work bud!
So once i tune my truck to run without the emissions do i pull the key out to kill the power before i unplug my egr?
Excellent video man. I am new to diesels and all I’ve heard is delete delete delete! Now I understand! I’ll definitely do it myself after watching this
How did it go?
Thanks for doing a good and clean job. Learned alot.
Thanks for the detailed video this is exactly what I needed
Awesome video, great detail!
Great work you got a new fan!
I'll be following this video as I fix my truck.
Followed your video for this, my only issue was the straps for the def tank cover that were high on the body side were torx bolts and stripped both so I guess the tank will be staying up other than that your video helped a ton the downpipe was extremely fun
great video. very helpful. thanks bro!!!
Great video. When done do you plug the first 3 plugs back in when done?
You have done this a time or two LOL, I want to get this done on my 13 D-max, great video Thanks!
Very informative brother.
thank you so much for the detailed video. Helped me breeze through this removal.
I love and agree with the comments about your content being thorough and no goofy music and foul language. Hats off to you.
I have a question.. Can I do a DPF delete without doing an EGR delete? I plan on doing the DPF delete with The H and S Mini Max. But I do not want to do an EGR delete if I can get away with it.
Yea that is exactly what he did
Great video! This helped me out a lot and I just finished the entire job. However I have a leak with that coolant pipe to the top of the bell housing! Wiggling it made it worse. Have any recommendations on how to tighten the tube in without taking new down pipe out again?
Can you specify Jou to tone or Prpgraming Ecm to work with out emisión , and no light on dash , I have to leave egr plug , unplugged, or the 3 plugs you mention in the video .!
Great video actually about to tackle this myself this weekend, just unplugging the EGR Will it cause problems?
Great tutorial!
As much as I hate the emissions on gm diesels, this was a very informative video.
Kudos for giving that disclaimer at the beginning to cover your butt.
If you're in Ontario you can't even sell this vehicle because no licensed Tech with half a brain will risk their license to pass these!
The fine for deleted emissions in Canada is around $10000 last I heard. Might be more now.
Just Subbed!!! Great vid, I just bought a 08 6.6 Denali , full deletes /lift tires and wheels upgraded!
Right on buddy! Thanks!
Great video 👍
Thanks for the videos man! I have a 2015 duramax that just threw a code for emissions 160 miles till max speed 65. The code was the egr has exceeded learning limit. Im going to do a basic dpf delete as soon as possible. Just worried that the egr is stuck open. It’s running great. A mechanic friend of mine told me that if that valve was suck open it would be running like crap? What would happen if I did the dpf delete and the egr is stuck open? Or maybe I can do the dpf delete and see what happens? Thanks again for the videos, id really appreciate some advice
Hey I recently purchased a 2012 lml that someone did this to but just welded in a straight pipe in its place and reflashed the ecm. Just curious where I should go from here I don’t have the stock tune or def and not sure if I do the full egr next or what looking for suggestions or options. Not really knowing what’s the next step.
great video ... whats the best set up for 2015 silverado 3500hd duramax ? i want to delete all the DEF crap. also if its deleted can i replace the system if i sell it? thanks again
Very good video !!
Will leaving the egr and coolers on be ok? I have heard different opinions and I am considering deleting but don't want to have to remove egr if it will be ok.
Can you please explain what and why you disconnected those plugs at the beginning?
Hello! I ordered a delete kit for my lml, did you end up removing the trans cross member to get that def injector muffler off?
Im thinking of buying the 2021 Duramax 3.L can you delete the DEF on the new trucks after the warranty is out ? And what would be the cost estimate?
do you have to do anything with the electronics, or just unplugging them do the trick?
Any long term effects of not using the DPF system then going back stock? For example if for some reason I wanted to do exactly what you did to mine then randomly every two years decided to go back stock.
Great Video. Where can I get the FloPro exhaust system? Direct from FloPro says no shipping to the US.
On 2016 3500 gmc if my truck has went into limp mode because of fail def pump will the efi live tune for def delete clear that or do i need to fix the limp mode first.
On this 2013 delete the 3 plugs you unplugged under the hood do you replug them in or leave them unplugged the throttle valve egr plug
Hey buddy when you finish with the exhaust you plug the wires back or no
Hey buddy i have a question is important unplug that wires you unplug in the engine
Hello, will a H&S mini Maxx work to delete? I don't want to throw money at a tuner if I have to leave the tuner in the truck. That was the description on website. Just want to make sure I'm getting the best information
Hey brother I've watched several of your videos. Awesome job. I want to ask you how long it how many hours do you charge for to do the full delete? EGR and Def
If I have some pre existing codes would I need to fix those before adding the tune? Asking for myself
Do you recommend a muffler with the 5" pipe kit?
Would this be pretty similar to the different body style 2016 LML?
I just picked up a 15.5 lml and I am having trouble finding a tune to delete the truck any help?
hey there , i just purchased my first lml duramax 2012 gmc , trucks got 306,000 kms , all stock , would you recommend a full delete ?? and straight pipe it perhaps ?
Cook video I have a 2011 deramax and I can't find a programer do you sell them my truck is for off road thanks
How do I reset to exhaust light if I put program on truck before I took off exhaust with a efi live
I just picked up a 2011 chevy 3500 reg cab I'm in love this is on my list subed
Thanks man!
Great video. Just got done doing a full delete and I got P249D code. Any help would be appreciated!
Thanks for the video! I have a 2012 GMC duramax and I need to delete it and install a 5” exhaust so this helps a lot! Question is though what tuner and tunes do you recommend?
Personally on a duramax I recommend just slapping a single EFI Live tune on. Either a 25 or 45HP level. 25 if you tow heavy lots and 45 if you mainly use it for daily driving unloaded
@@darkirondiesel is 100hp too much not towing?
So are you supposed to leave the three plugs under the hood unplugged?
Not sure where you're located, but would be willing to get my truck to you if you could help. You're clearly the right guy for the job. I've got a 2012 Silverado 2500 HD. Was driving back from a very long trip and just made it back into Minnesota while towing an empty 24' enclosed trailer. Speed was relatively low, about 60MPH and right as I accelerated to pass, there was a loud gunshot sound. The bang sounded like it came from behind the truck but not from a backfire as it never has in the 40,000 miles I've owned it. It was nighttime so I couldn't tell if it was dark or white smoke, but there was a LOT only while using the diesel pedal. DPF message came on about cleaning the tank, so I stopped to fill it, hoping I could just limp home. After filling, engine power reduced message came on and the trucks speed was limited to 39mph by GPS. 40mph per the dic. Took a few miles to reach that speed as well. If I put the pedal down to accelerate the engine would surge down like it was shifting into a lower gear like a exhaust brake, though the exhaust brake was off. If you're willing to lend some advice so I can DIY or if you're willing to physically help, feel free to call or text 6125014095. Really look forward to hearing from you. Codes P2463, P0420, P0299.
Thanks to anyone for any educated reply.
Hmm that's strange, I don't know what would cause the loud bang sound. The first two codes are emission related, but I believe that third code is turbo related. Super tough to diagnose without actually seeing the truck in person. As for location, I am located up in Saskatchewan Canada, so I doubt you would want to lug it all the way up here haha
One more thing I have been struggling with, My SCR went bad on my 2016 Nissan Titan XD at 23 thousand miles November of 2020.. I live in a no emissions testing state and Nissan does not warranty emissions systems in those type of states.. Go figure.. Even my crappy extended warranty did not want to help out.. even told me if I was to take it off they would probably not cover most of anything in the drive train.. So my question is this, I don't want my truck to be much louder than it is now, and not to look like a coal burner. Is that possible? Thanks..
I'm new to diesels. What happens if you tune the truck for a dpf delete but don't actually remove the factory exhaust?
Any recommendations for mechanics in Huntsville, AL that can do this?
Nice job wish I saw this before I did mine! How about a video on egr delete and up pipe.
That’s coming soon buddy hopefully this week!
Egr video is up buddy! Check it out
@@darkirondiesel Thank you!
Just subbed...Thanks for your excellent video... I have 2011 Duramax and after watching your video feel that this delete is something I can tackle. Your tips and attention to detail are awesome. I love the Flo-Pro product and would go with the SS864 but I live in the USA and I am not sure where to get it? Also I’m torn between the EZLynk and the H&S Mini Maxx? Any insights would be appreciated! Sorry about the length of this post but I’d really love to pick your brain about this!!
Honestly if all you are doing is just a basic delete, a Mini Maxx will be fine. If you are wanting to do some serious engine upgrades you will have to go with custom ezlynk or efi live tunes
Dark Iron Diesel
Thanks for your reply. That is good to know. I have decided to upgrade to the AirDog 2 4G fuel pump as well. Hopefully the Mini Maxx will still be satisfactory?
If the truck is already in limp mode and decide to do delete will this get rid of limp mode? Or does efl live or any programer erase the limp mode
Hello I'm thinking about doing this to my 2013 duramax. What do I need ?
Im trying to get the dpf deleted i have efi live it’s not legal here in the US were i am but im using this vehicle for track and off-road use only, on another note im looking on efi live software but the software don’t have the option at all. Any tips or helo would be greatly appreciate it
I have a 2016 hd2500 6.6. I would like to do the same thing with my truck. To many problems with the def system. Is the part number you installed on the truck the same for my truck? I searched for the on 664nm and can’t find it. No listing anywhere in my searches
Do you do this professionally for private parties? I live in a state that has no requirement for emissions control testing.
You’re brave posting this stuff
Why’s that? Where I live you can go to any local truck accessory store and buy this stuff over the counter.
Do you leave the 3 plugs under engine unplugged?
Yo i got everything but the delete part with the programing and stuff idk how to do that
Love it❤
so your saying that the truck will still run without the throttlebody plugged in ?
ok so you don't have to do anything with the egr valve?
What kinds of mpg are you seeing after this ?
Is this the same process for a 2015 Denali ?
Dude, you’ve got a lot of faith in that plastic ramp.
Even if they fail it still won’t crush him it’s not like he’s working on a corvette with almost no ground clearance. But come this guy is a pro
They make hanger pliars that make taking the exhaust off the black rubber super easy
Cool video man! What website did you use to download your efi live tunes for the last video you made with that white 2016 Cummins?
Thanks! And I get the tunes emailed to me from a company. If you send me a message on Instagram I can explain more @darkirondiesel
I have to say, you have the most informative videos I've ever seen on here. You know how to move the camera so we can clearly see too. Thank you. l do have a question that I can seem to find an answer to....I have a 2013 Durmax 2500 HD with the LML motor. I bought it from a used truck dealer about 6 years ago. What I didn't know is the the def system had been deleted until I took it back a month later because of a hose hanging down. They said it was "chipped and deleted" Now, years later, the motor is blown and I am going to be having it replaced with a "drop in" stock motor. I didn't think about that?? What would I need to do? Buy and replace the exhaust system? I don't want to go to the DEF system.
Just replace the engine but keep the ecm and exhaust you currently have. Also, you should get the trim codes from the injectors in the new engine and have them programmed in with a scan tool (a normal repair shop should have a scanner capable of doing this)
Thank you!
@@darkirondiesel
What about the nox sensor directly after turbo outlet
did you plate off the egr?
About how long did it take you to delete the truck ?
Does the check engine light stay on?
Hi man! I enjoy your videos! I have a question if you could answer for me.. I currently have an h&s tune on a 2013 lml and just curious if low boost fueling is effected when removing speed limiter? I had it removed with low boost set to 4.. throttle was very responsive. Later retuned to keep speed limiter on so I would have cruise however now throttle response feels sluggish. If you can't answer no problem! Thanks for the video though! Very infprmative👍
Hmm I’m not sure, what you could do is program truck back to stock, then program the tune back on it and select the settings you want. That way you know for sure how it’s set up.
@@darkirondiesel
Yeah indid that..lol by accident I turned key from on to acc. Then tune froze so I shut everything off and started over With the tune I had to begin with. I have it set to low boost at 4 like before but with speed limiter on.. and throttle seems like stock.. I will try same setting tomorrow but remove speed limiter like I originally did and see if that is what it is. Thanks for replying sir!
@Dark Iron Diesel I’ve got a 2015.5 all fully stock with 150kms...the DPF filter must be cracked because it’s a decent smoke show during a burn off and I get a puff of black smoke on takeoff during normal driving. No codes, been like this for about 2.5 years and runs fine otherwise. Am I causing any harm to the engine with a cracked DPF? I Will delete it but still researching the best option for me (fuel economy, reliability and CP4 longevity...)
I’m not sure that’s weird, I honestly don’t know if it’s bad for your truck or not. I would think it would be ok but I’m not 100% sure
Hey how do you get tunes for your ez link tuners.
I have a 2015 gmc denali 2500 6.6l I would like to do the same
I have a truck diesel I want to do it like that please I need more information
So it dosen't need tje oxygen sensors or pressure sensors anymore ?
What should i pay a shop for this kind of work? Thanks
I have a 2021 GMC with the 3.0L Duramax and I have been trying to find everything that I need to make my truck better but have not been able to find anything. Could you guys help me out
Thanks for the video! I am getting the DEF poor quality warning on my Duramax 2013 and was wondering if, for now I can just unplug the sensors and do a DEF delete reprogram and leave everything else installed?
No do not do that. If you program the truck to run without the emissions system then it won’t do DPF burns anymore. And if it’s not doing burns your DPF will plug up with soot and you can cause some SERIOUS engine damage. You have to install an aftermarket exhaust when you program the truck to run without emissions.
The first one is the nox sensor on the turbo
What if you’re already in limp mode before you start the process?
Great vid....2 questions...my truck is in limp mode already, will the tune and delete clear that out. Also will the three things under the hood remain unplugged after modifications?
If your truck is in limp mode because of a failed emission component then yes the delete will clear that. And unplug the 2 egr valves and throttle valves under the hood and leave them unplugged
@@darkirondiesel yes sir thank you, limp mode will no longer plague my truck.
Do you recommend the FLOPRO exhaust over other brands? Getting 5" (no muffler) for my 2015 LML soon. Thanks!
I dunno an exhaust is an exhaust, there isn’t really much differences between the brands. I like flo pro because they are Canadian and it’s easy to get them where I live.
@@darkirondiesel thx man
Hey bro couple quick questions for ya, those three plugs you unplug in beginning of this video , do you leave those disconnected permanently, and if you do plug all three bak in will it cause any problems like limp mode or any other issues ? Thnks appreciate it
Everything I unplugged will remain unplugged
@@darkirondiesel even throttle plug on 15 lml too?
Great video. I'm going to turn my $100k truck into a offroad truck now
I plan on setting up my own hot shot business. Is deleting a LML a bad idea?
I am about to delete my 15.5 lml, but I don't want the truck to be loud. Which exhaust do you recommend? Not sure if I am going to go with 4 or 5 inch, but I am not going to use it for racing or screwing around, it is a family rig pulling my camper and my ATV's around. Which tune is a good all around tune? Thank you.
I’d just put a 4” with muffler on it if I were you.
Will this exhaust kit fit a 2013 LML regular cab long box.
It should, sometimes with reg cabs you have to cut a piece shorter though.
