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!

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.

[@taltonbane]

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

[@taltonbane]

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.

[@pamtillis4673]

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.

[@boraxguy8302]

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

[@freetoride003]

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.

[@jimlahey6938]

Is it hurting the truck life at all or is there any negatives to unplugging and blocking off the EGR without removing it fully?

[@mohamedabdelsamie3128]

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

[@Guerrero1187]

great video. I believe the sensor in down pipe is the 9th injector for regen.

[@darkirondiesel]

Yes correct

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

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.

[@darkirondiesel]

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!

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

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?

[@jaxonsmith9551]

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.

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.

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)?

[@darkirondiesel]

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.
