In this video I will be going over the procedure to delete the EGR on a LML Duramax. The truck in the video is a 2016 Denali HD but the procedure will be the same for any LML Duramax. The kit I am using is a Deviant Race Parts EGR delete as well as a 3" Flo~Pro downpipe. A fairly common problem when doing this delete is snapping one of the bolts on the turbo which happened to me, so I also go over the procedure to remove the turbo so you can drill and tap the hole if you break a bolt.
To do the EGR delete you must also delete the DPF and tune the truck to run without emissions.
**If it is illegal in your area to drive on public roads with a deleted truck then don't do this! This is for off-road use only!*

How in the heck do
You remove the passenger side egr? I’m about ready to torch my LML

Let's delete the EPA
Thank you so much for this video. I used this one and your DPF delete video deleting my 2012 this weekend. I got lucky and after pulling the heat shield my down pipe came right out like nothin. Had one hell of a time getting the bolts outta the turbo but managed not breaking any. Thanks again for what you do on here man.
I fought with my downpipe for way too long, I learned words that soap won't fix. With no luck I spent 10 minutes removing cab bolts on passenger side and jacked up cab, down pipe fell out. Don't cuss, don't bleed, don't waste time. Jack the cab before it jacks you!
Yes I will try this next time!
@@darkirondiesel Also, Topside Creeper :)
This saved me from cussing and learning new words
I cut mine out lol
HOLY COW! THIS VIDEO CHANGED MY TRUCKS (LUCILLE) LIFE. THE WHOLE PROJECT TOOK ME 2 1/2 DAYS BUT, IT WAS WORTH IT. THANK YOU AGAIN FOR THE STEP BY STEP.
How did you get that lower passenger side nut off the passenger side up pipe? Literally only thing holding me back right now. I have sprayed so much kroil the past week.
One of the best vids on all this work, editing/sound/vid is top notch! Enough details for the average guy who wants to do this.
Thanks so much for this video. Completed this delete. Only add is we did lift cab about an inch to help with removal of downpipe. But you were spot on, job is a ------. Truck runs so much better. No bolts were broken, lots of PB used.
Thank you, I started lifting the passenger side of the cab a couple inches since this video as well.
just a quick tip for future down and up pipe removing! remove the two cross member nuts for the transmission and loosen the two engine mount bolts then jack up the rear at the transfer case. it will create a few more inches of space between the firewall and the engine and all three will be easier to remove and save you alot of cursing and blood.
Thank you sir
Sounds like a great idea.... just wish I understood exactly how to do that. I'm just getting into diesel trucks and costs too much for a mechanic so I'm learning how to work on this thing 😂
Didn't do mine. Staying stock but have done a few. Having host I lift the cab. Actually saves time and easier getting to everything
Just to clearafly I worked as a mechanic in the oil fields in Canada when I helped do this delete which I understand isn't illegal there. Seen a couple of mud boxing diesels that had the whole delete and programs done but wasn't much left ot the cabs .easy to get to most everything which is good because of the broken crankshaft or piston breaks.
After taking the cab off, is the truck now a rattle noise problem? I’ve read where guys say don’t take the cab off because every bump you hit the cab now makes noise and acts lose and it’s not the same truck anymore.
Don’t want to delete mine but having the EGR valve so out at only 30k miles makes me fear the lack of dependability this crap DEF system causes.
Thanks for being honest about how much of a pain it is to do this job. I’ve done it and know exactly what your talking about. A lot of the prior videos I’ve seen don’t show the aggravating parts of this.
Absolutely, everyone online talks about the pros and cons of deleting it without even mentioning the hassle of the parts or the price of getting it done at a shop which in-itself is a pain to find one that will do it
Thank you so much for this video. It was an absolute life saver. I must have referred to it 30 or 40 times. You're right. This job sucked. My hands are so bloody and bruised!
Thanks for the great video very informative and changed my mind on doing it myself my patience level will not handle stuff like a broken turbo bolt and removal. You ,however did an excellent job defining the difficulty involved , I subscribed because of the terrific job you did.
Thanks again.
Thanks man. I don’t even do these anymore, that’s how much I hate them haha
Lol same
I pulled my down pipe once on my LML, ill never do it again. Great Video.
Hahah they are awful
I pulled mine last night. It was a nightmare! I thought I pulled the 3 bolts on heat shield but missed one. I fought it for 3hrs and finally was able to get it out with the heat shield still on. WHAT A MESS! LOL
@@TheJoe111599 wait till you have to do a starter. Only way I found was the remove the downpipe again. I paid the dealer this time.
@@TonyPreckwrinkle screw that mess. I'm never doing it again. I can't stop working on something until it's done so I was out pulling that POS till 1130pm last night lol.
This video was very helpful and saved me a ton of time by you saying what size socket for those hard to reach bolts. Thanks! 👍
great video. I believe the sensor in down pipe is the 9th injector for regen.
Yes correct
Ratchet strap is what got the Lml down pipe, wiggled and ratcheted at the same time and it was easier than I thought. I pulled the heat shield out first.
Where did you get your delete tuning?
If you got another person hitting the heat shield from the top forcing it down with a pry bar and some pulling down under with vise grips it comes out quick, just thought I’d pass the info for the next guy doing this
I've been referencing your video as I'm doing this on my 15 lml. Currently stuck at that metal coolant pipe, just having a fight getting it out. Most of my up pipe bolts are out other than the ones you can't reach. Excellent video and references yeah this job sucks lol
That look like a mission😳 I'm replacing my cp4 as we speak and I m thinking about deleting since I'm already in there, what a pita
I’m also in the same boat as we speak and I wanna pull my hair out 😂
What are you replacing your CP4 with and where did you get it from, if you don't mind me asking?
@@MrLazlott I went with cp3 10 mil I bought from a guy locally in Miami, he sold his truck so I bought the pump, injectors, 64mil turbo from him for a good price
@@johnsondml I've been torn on the CP3 or CP4K. I have a lift pump, but I know the 4 is a time bomb waiting.
@@MrLazlott ppl talk down the cp4 pump but with a lift pump behind it you're ok, ive seen cp3 pump fail just as well as the cp4, I think you'll be ok with the cp4 and lift pump, ive seen allot of cp4 pump still running @ over 600k miles trust me
for delete a egr dpf def first you need remove all sensor or after remove all sensor
Guys one of the mistakes is to loosen the 11mm nut on the down pipe clamp before getting both shields off , start with the small heat shield it will come seay from the side then the bigger one u have to pull it from behind too and wiggle it a little bit but it comes out easy 2, after that loosen the 11mm nut for the down pipe turbo clamp and it slides easy down
Is it hurting the truck life at all or is there any negatives to unplugging and blocking off the EGR without removing it fully?
Great info: What about DELETE you mention before starting ,what do you mean by programing
I inquired about the egr delete at the dealer and they lift the cab up to do it
Amazingly detailed video! Super helpful.
Thank you!!!! 👏🏻👏🏻👏🏻👊🏻
I j helped my mechanic with an EGR delete on my 2015 GMC Sierra 3500 HD Denali DRW. I did not have my tuner yet.
After completion, my air conditioning suddenly doesn’t blow cold ( 2 month old compressor is not engaging.)
Mechanic said I needed my tuner install and it should work .
I ordered the tuner and gave the info for mods I was planning to go ( I have all parts )
EGR complete
Dpf delete Sensors disconnected
Cold air intake installed
Fass lift pump Not installed yet
5 in flow pro straight pipe not installed i
Down pipes Not installed
Up pipes Not installed
EFI live tuner arrived I installed the switch and flashed
Seems to run fine , no engine light
But my driver window doesn’t work
Back up camera doesn’t work
Air conditioning compressor still not engaging
Bummed out the screws for continuing any more work until I get this right but I’m not driving the truck. Put a snap on scanner on it and it had no codes.
Never had those issues before personally, but YOU CANT RUN A DELETE TUNE WITHOUT REMOVING FACTORY EXHAUST! The delete tune deactivates all the regen/burn process, so your exhaust is going to plug up and you can seriously damage your engine!
If you haven’t already, do a video on the EFI Live tuning. Really helps. Thanks.
Thank you sir for this helpful video.That metal coolant tube is holding me up.Wasnt sure how to go forward with it in the way of that one up pipe bolt to turbo.2 bolts are all that's left of 9.Ill be so glad to finish this install.Ready to work on something else.I drive 18 whlr x country and limited time at home.Ive been on new up pipes install for 5 months now,and still in removal stage.Not started putting new back on.
I feel your pain, also a trucker and not much time to devote to getting my truck done either. Also need to replace my CP4 with a CP3 and all the injectors / rails. Can't wait.
My truck is EGR/DPF deleted but want to make sure it's more reliable so I have purchased the following:
cp3 conversion (no - tuning required, no 9th injector)
new up pipe
3" down pipe (no bungs)
egr delete kit
Fass Lift Pump
The EGT and O2 sensor for the down pipe can be discarded correct?
I know I'm looking at a 15 hour install, just waiting until duck season is over to begin the fun. The truck is off road use only.
What kind of MPG difference do you get on your LML now
Broo u make it look so easy!!!! I wanna try doing it,,, ime mechanicly inclined but i know myselfe and i know wrenches will start flying… whats the going rate in a job like this if i pay for parts??? I might just have somebody do it for me.. i can do dpf delete,, exhuast install and lift pump.. ime scared of doing this though
Random dumb question I'm having issues with the def side of my emissions can I just delete my dpf and leave the egr but unplug them?
@darkirondiesel thanks for the video. Did you ever figure out which of the two sensors on the top of the downpipe are actually required? Also, is the third "sensor" down on the lower end of the downpipe not just the 9th injector? I've read that you can just plug that. Thanks again for the instructional video.
I was told the down pipe is optional and does not need to be replaced, can you give any more detail on why or why not replace it?
Is there any additional tuning that need done once it’s removed?
ever figure out which sensor has to go back into the new downpipe? you said mayb discard the one and flipped it back, and then mayb the other side one goes back in,,,ever figure out which ones which ?
Do you think you can get the up pipe out without taking out the downpipe?
No
AWESOME ! Video! Thank you for helping everyone. Hmm I bought a 2011, with the EGR delete already done. I'm having a difficult time trying to find the coolant hose, from the engine to the cab. Its leaking at the back of the motor. Any thoughts, ideas would so much appreciated, Thank You !!!
Are the coolant lines ran the same on all LMLs? I have a 2011 3500.
I installed the kit from the diesel dudes ( down pipe , y pipe, coolant hoses & blocker plate )
Mu temp gauge hangs at 210 them jumps to like 211/12 then drops to 208/09 , is that just the thermostat cycling due to more flow ?
Replaced the thermostats , temp gauge , coolant flush & still the same
Ya I wouldn’t worry about that minor fluctuation
What do you have to do with the transmission or will it hold up??
Did u get a chance to try and jacking up the cab? I’m struggling with my down pipe and can’t find a way to get at the 3rd bolt on the heat shield. And feel like I’m gonna break something when I try and ratchet strap it down. Any tips??
Thanks for the video, this is a tough job even with a video, I could not have done it without you thanks !!!!!!
Can you please make a video on the l5p. Please. Thanks
for delete a egr dpf def first you need remove all sensor and put the tune or after remove all sensor put the tune
It doesn’t matter
@@darkirondiesel u sure I’m scared bro
@@darkirondiesel so don’t matter before or after remove all sensor for install the H&S
Whenever I tune a truck I always tune it first before I touch anything on the truck, then after make sure the truck still starts. Then unplug the sensors and try to start the truck again, make sure it’s running with no engine lights or codes to confirm the tune worked, then shut off and remove the dpf/egr. But like I said, it doesn’t actually matter which order you do, that’s just what I do
so this will probably sound a little sideways but i used to wrench for a living... this job would seem a lot easier if you pulled the radiator and exhaust pipes and the trans and motor mounts and slid
the motor/ trans forward... what say you??
Man thank you so much. I know how much patience that must have took. Good job man!
Thank you for this video, the uppipe @13:28 is cracked and leaking for 2nd time. Its gotta go
why does the down pipe need to be replaced? I was told it isn't necessary, can you clarify?
I ordered a delete kit but I choose the option without the up pipe,does that me I don’t have to pull it out?
On the intake side block plate you used the factory gaskets mine has orings do I need to use the factory gaskets as well or is it a good idea to I'm not sure if yours had orings
No just use the o rings
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
Do you leave the throttle valve unplugged?
That sensor on the middle of the down pipe is the 9th injector, could could delete it if you want. The 9th injector will be turned off when you tune the truck.
I enjoy watching your stuff. Always nice seeing Canadian content 🇨🇦
WOW…I’ve been in performance industry for over 60 yrs..this job I would not even consider ..is it possible it would be easier to remove the engine?
A very impressive job…you are very talented..
Just how much does a day of torture cost
No way, pulling the engine would be 100 times longer.
Lift the cab
Would it be better to just use a coolant bypass instead of that hose with the kit?
What year is your truck I need remove egr my 2022 it's same?
Question please. If I delete the egr my self and I have a hand held tuner like a mini maxx can I tune it myself or do I have to have a shop dyno tune it?
The tuner already has the dpf, def, and egr systems programmed out of your ecm. You should unplug the sensors so it won’t throw your truck off and can cause it to run weird. If you start adding more performance parts you can go back to retune and get the most out of your parts (I believe). As of deleting the egr physically you shouldn’t need a retune.
@@jaxonsmith9551 gotcha thank you for the input man
is it absolutely necessary to remove the egr? or can you just unplug the sensors and just by pass it with the tune
Thats how mine is done. Tuned and unplugged with blocker plate. After watching this, i don't see the need to get in there and go to torture fest because the LML runs fine like this. Other than lose a little weight but thats a non factor on a 9000lb truck
@@MrMotor11But could you agree that this could affect turbo spool time?
@@nickolasgiampietro3164 Since that time i've had the items mentioned removed. So i got to experience it running with all the EGR parts, blocked and totally deleted. Honestly, i don't feel much variation but then again with a straight 4" exhaust the whole time there was never much resistance to spool up so i might defer this question.
I’ve got a question about the small coolant line that you didn’t mention what you do with. It comes off the cooler and Ts into another line that you didn’t cut toward the passenger side. Any help would be appreciated
I have a different egr coolant hose that has 2 hoses connected that looks like a V shape will that work with 2016 lml?
I got the ez lynk tuner. My dpf is backed up and blowing air. I have no power to the truck right now. What should be my first step?
Tune truck, remove exhaust, unplug egr.
I have a 2015 lml, had def problems, it’s now deleted with efi live, but now it keeps giving P249d code and it won’t clear. Confirmed with tuner all settings are correct in program. Any ideas? Is there another way to clear?
Can you do video for the l5p
What kit do you recommend getting for this complete delete?
It’s wild how much more complicated this is compared to an l5p
Will a bad Def modulator cause the truck to throw a EGR bypass valve stuck at ten degrees open code and send a check emissions now alert to the dashboard with a speed limiter warning attached to it?
Sounds like you have 2 separate issues to me. That egr valve stuck open will be its own issue. I’d definitely get that fixed ASAP
So what do you gain by doing this modification?
Don’t you hate when that happens 😅. Whoever owns that truck has clean tastes, great looking truck.
Ya it’s the worst! Had to work all day Saturday to get it finished for the customer but oh well, what can ya do.
What all sensors do I unplug to bypass egr until I delete the egr
Amazing Video!!!! I did mine and boy… it was not a fun job. But the smiles after it’s all done and my tools are clean and put away… I’m smiling from ear to ear!
QUESTION- on the thermostat hose… the hose that you ran from the thermostats over to the fuel filter area…. The clamp that you used to fasten down the hose… do or have you ever had problems with the hose blowing off due to pressure? Is one clamp enough to fasten down the hose ???
Where did you buy all the parts to do this job?
How do you know if your truck been deleted.
I just got a 2015 3500hd denali duramax diesel. My first diesel.
Looking under the hood I found 2 sensors unhooked 1 on the passenger side near the firewall
1 driver side middle of motor they said there 3 sensors but only saw 2
Look at the exhaust, if there’s a couple big filters and sensors plugged in then it’s probably not deleted. If it just looks like a normal exhaust with no big filters or sensors it’s deleted.
I believe I missed a sensor, my check engine light is still on. A list of sensors that need to be unplugged would be very helpful.
do you know any where else reputable that sells egr delete kits deviant diesel no longer sells them
I am doing a EZ Lynk, EGR Delete with up pipe, down pipe, and 5” exhaust. Do I need to delete DPF, DEF, and tune before my EGR removal? Or can I do it all afterwards?
I saw his video on the dpf delete and he said to tune it before you unplug and take stuff out.
@@Mattss90 so tune, take dpf out, and then egr?
@@kolyncantrell6762 I’m not 100 on that. I just know he said to tune prior to taking cat and dpf out.
What tune you going to run??
What type of turbo was in that truck and what was the fleece part in the beginning and how is it helpful
Just the stock turbo that comes with the truck. That fleece thing is a turbo resonator delete. Gives you a bit more turbo whistle
Dark Iron Diesel thanks man
Pull cab bolts and jack up in the resr of cab only like 6 inch . And losen fronts welcome
i love how he gives his disclaimer when it is federal law so it is illegal in every state. But it’s only illegal if you get caught.
He lives in Canada. It is not a federal law and Not all provinces (Alberta) make emissions removal illegal.
@ thank you for clarifying. I assumed because he said check the state you live or local laws he was from the USA. In hind-site I am sure a big portion of his audience is from the states which is why he said that.
I have a ? 08 lmm I did egr delete and removed throttle body pipe. Do I have to program ecu or efi tune????
Yes if you don’t want a check engine light and you want it to run more efficiently. You also need to get rid of the factory exhaust.
@@darkirondiesel I do have exhaust. So do I reprogram ecu or efi. Again thanks
What headlights is your guy runnin?
I bought a new up pipe so i used sawszall and pulled old one out in 2 pieces
I just did this and the turbo is very loud, is that pretty normal?
I have a 2013 durimax. Ive ordered the 4inch pipe with the EFI tuner. The kit also includes the EGR delete kit. It comes with the uppipe but they say I dont have to replace the downpipe. Do I need to replace the downpipe?
You don’t have to but honestly it’s such a pain in the ass to take out and even worse to put back in so my advice is if you got the factory one out get rid of it and replace it with a better flowing 3” downpipe. Also goes in way easier
@@darkirondiesel thanks ordered one. And one more question. Im seeing everyone deleting the 9th injector, is that something I should do as well? I'm doing this all at once. Just waiting on the downpipe to come in.
What I got... but havent installed yet is a 4 inch straight pipe, EFI Tuner with the "on the fly" switch, EGR delete kit, uppipe and downpipe. As I said, doing everything at one time.
I’m doing the def and egr delete on a 2011 duramax. It is already limited to 55mph because of def problems. I did the def tank and exhaust removal and also did the tuning with a Mini maxx tuner. Do you think it will still be stuck in limp mode after I’m done.
Nope as long as the minimax had the “emissions removed” setting and you selected it you will be fine. You can just get rid of the exhaust and unplug the egr, you don’t have to physically remove egr if you don’t want to.
Dark Iron Diesel thank you so much 👍
Same exact thing happened to my 15 lml. It’s throwing codes for a bad egr valve. I ordered a flo pro exhaust and a tune so hopefully it clears the code and let’s me go fast again.
What’s wrong with just unplugging both egr plugs and just leaving all that alone?
Do you have a link to all the parts you used
I have a dumb question. When i do a def and egr delete on a 16 Silverado 3500. do i need a tuner so i dont have any check engine light on?
Yes
@@darkirondiesel what do you recommend. I live in Florida. If that makes a difference.
Will it be ok to leave everything after the delete and the egr unplugged?
You can leave the egr but not the dpf
@@darkirondiesel ok just making sure thank you . i bought my truck this way
What did you do with the hoses you cut the other ends that were left in the truck the ones off the egr
Once I got the egr out of the truck there is much more room to work with. So I removed the cut off hoses from the truck, then replaced them with the new hoses.
Dark Iron Diesel hell yea I saw that towards the end I’m gonna attempt this on my 2012 lml thanks man
Why do the full egr removal delete? I have a 2015lml and when I was looking into doing the delete , I was told by a couple gm techs to just unplug it and install a tuner. Then its not working anymore..same principle...
I did the full delete on my lmm.. just as nasty!
These gm guys said if they were to do the full delete they unbolt one side of the cab and till it ...makes it way easier.
Yeah you can do that but it will still open under boost. The full egr delete will eliminate it completely. Doing my full delete next week on my 16’ LML
@@HardEnduroLlewellyn that’s only on the lmm
@@gobigorgohomeproductions458 false, under heavy load they have been known to open. It’s not common but still does / can happen.
Also I’m not installing any aftermarket down pipe or up pipe. Do those need to come out to get EGR out?
No if you’re using a blocker plate you don’t have to pull the up or down pipe
Well I ended up buying a down pipe. I don’t see how the EGR comes off east without doing the down pipe lol! Thanks
For the video! Def helped me. My trucks been in my Garage for a week! Third time I watched this video I realized that tube had another bolt holding it in to remove! That one almost broke me before I saw that!!!
@@darkirondiesel thanks! By far the worst thing I have done on a truck or car. I’d rather put long tube headers on a GT500 without dropping the K meme er then do this again!
Kyle, while trying to install my 2018 6.7 Cummins tune with an AutoCal, I get an error message on the AutoCal that says ignition is switched off. IT WASN'T OFF. Have you ever had this error $0549 before? If so how did you work around it?
I haven’t seen it before unless I forget to turn the ignition on. My advice is contact the company that wrote the tunes. Also, make sure you are using the 2018+ Cummins bypass cable.
So waiting on my EGR Delete kit. Can I tune it and delete def and strait pipe it, and just unplug the Egr for right now? Or do I have to do it all at once?? Thanks for your help
Yup you can
What kit do you recommend!
This kit right here shrsl.com/4ke0v
What do you charge to do a job like this?
How did you move the exhaust to get the Downpipe
Being as how I live in California, I can’t pass smog by doing this stuff, however I plan on doing it regardless. But can we just tune the truck to where you don’t need to take out the EGR or the up and down pipes? It’d make my life easier if didn’t have to take off and put on ever few years.
Yeah you don’t have to do the egr delete. You just have to remove the factory exhaust then unplug EGR and throttle valve. The tune will deactivate the egr so the valve stays shut. Most guys leave the egr on because it’s such a pain in the ass to remove.
@@darkirondiesel yea I figured... is there a perk or good reason to be taking it out?
@@Mattss90 you take it out so there’s no chance of exhaust gasses passing by. I’m deleting my LML when I get my parts and I live in California as well. I’m doing full EGR delete with up pipe, EZ Lynk, 5” exhaust, and PPE down pipe. Should be a fun job.
@@Mattss90 yes there is one other reason for removing the EGR.If/when there's a leak of any fluid you can find it quickly and easily with less engine congestion to block view.If still using the OEM type CP4 fuel injection pump,it'll eventually eat itself,so yanking the EGR makes swapping in the better CP3 pump.
It helped me. It helped me decide not to try this. Ridiculous. When I deleted my LML, instructions included disconnecting 3 connections for egr delete. Do you know what the difference is between that and what you did ( besides physically removing egr)?
Haha ya they aren’t fun. When you delete the dpf and install a delete tune on a truck you have to unplug the throttle valve and the 2 egr plugs on an LML. Basically it deactivates the egr system. The valves should remain shut therefor not letting exhaust back into the engine. Guys will physically remove the egr system for a few reasons. One is for peace of mind, if you remove the egr system and block it all off then you KNOW 100% that there will be no exhaust going back into the engine. Second reason is that sometimes the egr coolers crack so you start burning coolant or pressuring up your coolant system. And the third is just for looks, it really cleans an engine up when you remove it.
You just did an "electrical" (or virtual) delete. He did a physical delete in this video. Basically you just disabled the components, and he removed them.
