Lower egts will have negative effects on dpf, it needs high temperatures to burn up the soot. Your regens will be much longer. Now you have lower boost because of the lower egts. Emissions compliant trucks do not always work well with aftermarket parts. Does gauge shows dpf load %?
That was Totally Awesome! Do you think if I done this to my LMM that I could get the same effect? With my stock exhaust system. I can easily get to a thousand degrees with the truck only on a slite grade especially in the exhaust gas temperatures. A Awesome post by the way.
I actually do not think they’re worth it. These diesel engines come with a five 100 warranty you shouldn’t touch it until it’s out of warranty. Even so there is an a lot of work for such a small return.
I got the up pipes and manifolds on my lb7 with an s475 compound and really love the set up max egt cp3 maxed out I’ve seen 1400 at a high elevation so I think it’s definitely worth the money and pain to get installed
I would like to definitely show some appreciation to truckmaster because when I first bought my lbz 4 years ago I basically instantly found his TH-cam channel and just seeing how much he has grown with new equipment trucks and knowledge is great because whenever I need a little bit of info on anything he’s got it on the channel, thanks for all the great content and everything you do in general
Great job Josh . Man your channel has come a long way . I love that you’re doing real world testing on these parts even if they are or aren’t purchased by yourself . Aka sponsored. I’m hoping you will give us viewers the same UNBIASED content for many years to come .
Good video dude! My freind at the dealership said he has done about 10 trucks so far with the same issue!! I will tell the other readers of this post that I have a 2021 Duramax with 127k on it. I drive cross country for a living. That's why such high mileage already. There is an issue with the stock manifold on the driver's rear cracking the bolts or warping the manifold where it Connects to the up pipe on the back side. Gm decided to use smaller hardware on the L5P's....Way to go GM!! So this kit Josh is installing is almost a must have!! I'm getting ready to have my drivers side manifold replaced under warranty I have a 150k warranty on my truck thank God! Hope this helps.
I just installed Danville turbo cp3 and 60 over exergy injectors as they crapped out. Plus some other goodies along with ppe manifolds and up pipes in my 05 duramax. It definitely changed the tone of my truck. Love it and not to shabby @ 650 hp to the rear wheels. 👍🏻
A pondering: by opening the flow of the plumbing, maybe that reduced the boost or psi in the system. I’m thinking of an HPLV and LPHV pneumatics system. If you have a constant air supply coming in…and you change the volume the air travels through, you will inadvertently change the pressure/boost in that system. More or less boost doesn’t necessarily mean more or less power unless you’re programmed for that pressure coming off the turbo.
Thank you for explaining the definition of EGT to noobies like me, helps out a lot that you do stuff like that on every video! Maybe you can make a video talking more about egt and everything else on the gauge to be looking out for?
I did this to my lbz a couple years ago, the only thing I did different is sent out manifolds and had them extrude honed ,don't know if it made that big of a difference but they where like glass smooth on the inside.. good video
I just did my 2005 LLY with up pipes down pipe and manifolds. Sounds better and dropped my EGTs a little over 100 degrees! Very happy with the outcome!
Working in a dealership and working on this stuff everyday, your right it sucks. lol. I put a down pipe on and lmm and for as long as it took me i could have lifted the cab and been time and money ahead, or least just lifted the passenger side a couple of inches probably would have helped to. But keep up the good work i enjoy your videos.
On a deleted truck the lower egts is great. But with emissions in tact you kinda want the heat to keep the dpf filter burned out or else it’ll regenerate far more, they need the heat the maintain emissions function properly.
Josh I love the L5P content. I have an LB7 and L5P, love them both. But I think you should do a weight reduction 😉 many big Tubers do it, just don't talk specifics and have fun with it! You'll be fine
Your boost numbers could have gone down because of the better flow. From what I understand, the higher boost you have, the more stagnant air you have chilling not doing anything. I could be wrong, but when I put my manifolds and up pipes on, I wasn't able to reach the 32 psi I had beforehand. Awesome video, keep it up man!
I am so pumped about the lower egt but I wonder if it makes the dpf less efficient since there is now less heat to burn off any soot, probably over thinking but very interesting to see and how much power was gained from this install on the blue L5P 😀. Love the videos keep them coming. Also I can't wait till you see the difference when you get it tuned, It made my emissions equipped lml with 35s and 22s feel like a totally different truck, it is also regening less frequently.
it probably will lead to more soot clogging the dpf. these trucks were designed specifically to run hotter to burn soot before it gets to the dpf. so doing this mod plus s tune and your probably going to kill the dpf filter at some point
For me too finish that job I need the driver side up pipe and the manifolds. I already got the passenger up pipe and down pipe with my High Flow bundle kit from WC Fabs. Now I'm thinking about getting those last 3 parts and doing those when I do the CP3 swap.
Lower egts are awesome !! That said if you are in need of a parked regen will the lower egts effect how the dpf filter needs thats extreme heat to clean out the filter for a full cleaning of the dpf filter??
A handful of 1300 max EGT with maxflow up pipes and downpipes race tune 250hp. 95% of the launches I never go over 1200. I have the edge set to alert me at 1300 and I let out.
Thanks for all the videos you do I really enjoy them. My truck currently has an exhaust leak and I’m looking to do this. One thing I noticed though is that the first test was on EGT on a cts3 which is pre turbo and the 2nd test was on EGT 1 on the CTS2 which is post turbo. I verified on my older firmware cts2 compared to my cts3. I was wondering if you’d be able to double check the results? Just so I’d be able to make a decision if it’s worth it to but the manifolds and up pipes. Thanks for all that you do.
Great video I have these done on my lml, for the lbz are the manifolds the same for a lb7? already have lb7 up pipe and they don’t seem to sell just manifolds without up pipes
you should look at the calibrated power/ duramax tuner tunes. they are emissions compliant and awesome. I have been running them for 10k in my 2018 Chevy L5P can’t say enough good things about their tunes, their shop, and their staff.
@@TruckMaster No problem! If you put all the intercooler and intake piping with their race tune you will be close to 600hp. plus their tunes are SOTF. And no i dont work their, lol.
I haven't dont any up pipes our down pipe like u did but I did hot and cold side and intake horn from wf noticed alot of noise tone change after the intake horn but installing one part at a time was hard to tell if the whole package really improved performance or not didn't have the money to do it all at once would like to see you do somthing like that see what happens all in one shot
I’m curious to see the EGT‘s after the install. Your baseline test was using EGT probe, and then your comparison gauge said he EGT1, the EGT1 probe is cooler than the one labeled only EGT on the edge cts3, thoughts?
Hey man, im not that big a fan of giveaways as they usually just have overpriced clothing but you actually have legit stuff,parts,tools,etc with great prices!💯 So today when I broke my dear little snap-on magnetic screw driver, was like what the heck I'll buy one from truck masters. Might have a tiny chance to win a sweet box too😅
Not to surprised that you seen a decrease in boost psi. To build psi you need restrictions and you pretty much eliminated most of the restrictions, pre turbo anyway. Good video and im curious to see how it works our for you!
Do you do these installs for a living? I have the identical truck including that Equalizer hitch except I had them make me an extended shank so i could lower my tailgate. What's the total damage for the install including parts and labor? You made it look easy but it's beyond my range anymore as I'm 77 years old.
We would all like a shop with a lift but most people would be doing this in the driveway, I know it was harder for you but thanks for not pulling the cab 👍😁
what kind of mileage are you seeing after that. Did it help. I have a 2011 duramax and I tow a 7000lb trailer and I get about 10 MPG. is that average or should I look at doing some work to it. It is all stock except for a K&N air filter, and an EGR delete.
I think for the average Joe this is a lot of work especially without a lift in their garage. It took you 20 hours and then some. So at $1500 plus change and labor to save a little bit of fuel. What is the payback time to even break even? My 05 GMC Duramax has stock equipment and 240000 miles on it and I pull a 10,000 lb. 5th wheel with it. No issues.
Getting ready to do my lly, got all the exhaust parts, getting the pusher Y bridge, hope my results will be similar. Great channel, keep up the great work!
What MPGs are you getting after this? If you were not going to tune and are only looking for MPG gains, which emissions complaint upgrades would you do?
I have a 2006 kodiak lly. I have heard that doing these mods do next to nothing on them, as they are detuned from the factory and already have different pipes then the pick up trucks. Do you have any experience with mods on the medium duty trucks? By the way, I only see max 20 psi on my boost.
So I’ve got a question to Truckmaster. I’ve got a 17 l5p and I want to swap in manifolds but I don’t want the egr riser on it. I am tuned and deleted and have up pipes. I was wondering if you knew or anyone know if lml manifolds would work as a replacement?
The reason why is because they are optimizing the use of those parts for different applications and options you can get on these trucks. If you can use the same part on twenty configurations, you can save a pile of money not only on the part but also on tooling at the assembly plant level.
What do you guys think about these diesel bolt on parts? Worth it?

That's a job! I wanted to do this to my LBZ for a while, after seeing this I'm for sure getting a kit.
My LBZ breaths way better after installing these
Truck Master I’m wondering if this job will be difficult for my 2WD LBZ?

Nice work!! It made a difference on my LLY too. Love the before and after comparison.
Hello Josh and Melanie. Your new truck is looking good. Can't wait to see what else you're going to do with the new truck and the rest of your trucks.
I just installed Danville turbo cp3 and 60 over exergy injectors as they crapped out. Plus some other goodies along with ppe manifolds and up pipes in my 05 duramax. It definitely changed the tone of my truck. Love it and not to shabby @ 650 hp to the rear wheels. 👍🏻
Nice 👍
its always so good to see good results from a hard project.
nice work man!
Thanks mike
That's awesome brother! When I have the funds, I plan on doing this to my 05 LLY and everything else CARB approved (gotta love the PRC).
A pondering: by opening the flow of the plumbing, maybe that reduced the boost or psi in the system. I’m thinking of an HPLV and LPHV pneumatics system.

Thanks for doing this. I have an lb7 I am going to do the ppe manifolds and pipes... it was cool to see the difference it made...
Definitely! Thanks
Thank you for explaining the definition of EGT to noobies like me, helps out a lot that you do stuff like that on every video! Maybe you can make a video talking more about egt and everything else on the gauge to be looking out for?
I’m considering them for my 14 Denali Dually, looks good to me!
Thank you for the update on the PPE upgrades - it is greatly appreciated!
No problem
Information about please
Ppe
All those high flow bits are definitely on my build list.
I did this to my lbz a couple years ago, the only thing I did different is sent out manifolds and had them extrude honed ,don't know if it made that big of a difference but they where like glass smooth on the inside.. good video
Did you test your egt before and after?
Just curious if you noticed anything
I just did my 2005 LLY with up pipes down pipe and manifolds. Sounds better and dropped my EGTs a little over 100 degrees! Very happy with the outcome!

Great video, ready for WC Fab to release their L5P manifolds to go with their up pipes I already have installed.
Do not think I would not want to tackle an L5P. Good job definitely going to get set for my lbz.
Thanks
great video man excellent work
Thanks
Nice work. I definitely saw a change with mine.
Thanks Phil
On a deleted truck the lower egts is great. But with emissions in tact you kinda want the heat to keep the dpf filter burned out or else it’ll regenerate far more, they need the heat the maintain emissions function properly.
Greasable upper ball joints! Smart engineering.

That is a good question and the comment made about designed to run hot is spot on. Had me thinking the same.
Good content, don’t let the haters tell you other wise

You need to get you a Milwaukee battery powered ratchet. By far the best money I've spent!
Awesome informative video as usual 👍 Keep up the good work!
Thanks
I would love to do that to my lb7but funds are tight.you haven't thought about trying the pedal monster from banks power I see a lot of videos on it.
Next up hot side and cold side inter cooler piping and cold air intake please!
Will do
Excellent video. Do you know the outside temps from before and after and did you notice an MPG difference?
The temp was almost the same on both tests
Probably makes more power with less boost as its now less restrictive which is a huge win.
👍👍
Was looking forward to seeing the PPE replacement deep motor oil pan video for you L5P truck
I’m getting to that video shortly
Great can’t wait !! Chopping at the bit to get started !! And look forward to getting some good tips
Another awesome video. Long time viewer first time poster. But I will say I literally watched 5 or 6 commercials on this one.
Boost is a measure of restriction. So, I would expect a lower boost number with a more free flowing system.
I would love to see a DYNO run after the exhaust parts you put on. To see the difference. I know the 17-19 trucks do around 403 @ the tires stock
Reducing the temp pre dpf could cause a decrease in passive regens. And decrease fuel economy. It’s will be interesting to see the long term review
I am liking this. Very cool. And legal!
Lower egts are awesome !! That said if you are in need of a parked regen will the lower egts effect how the dpf filter needs thats extreme heat to clean out the filter for a full cleaning of the dpf filter??
No it will still Regen just fine
AWESOME VIDEO!!! 👍⭐⭐⭐⭐⭐
Thanks!

Or just to let me know what your EGTs have been on the new setup.
Can you also give us an idea on if there is a change in MPG?
Great video I have these done on my lml, for the lbz are the manifolds the same for a lb7? already have lb7 up pipe and they don’t seem to sell just manifolds without up pipes
I like your videos!
I’ll be in the market here soon to buy my first duramax! Fellow Michigander as well! Quick question, what monitor do you have in your truck here?
you should look at the calibrated power/ duramax tuner tunes. they are emissions compliant and awesome. I have been running them for 10k in my 2018 Chevy L5P can’t say enough good things about their tunes, their shop, and their staff.

I don’t have to do this nor will I probably ever have to but I still watched the whole vid, and I know it can be done haha
Thanks Cody

I actually have the hspdiesel stuff ready to go! I will have that video done probably next week
Josh, would you say you are getting more or less regens after upgrades?

That’s awesome man thanks
Damn! Can't wait to get mine but not looking forward to putting them in
Install sucks 😂
I think the boost hit 30 before because boost is essentially a measurement of air restriction
You're monitoring different egt probes in the before and after.
Get a intake horn with Pcv reroute
That’s very impressive Josh, but if you were to do it again would you pull the cab?
Probably not
Great!
I would love to buy that truck.😎
Great video.
Thanks
Not to surprised that you seen a decrease in boost psi. To build psi you need restrictions and you pretty much eliminated most of the restrictions, pre turbo anyway. Good video and im curious to see how it works our for you!

Do you work on customer trucks?
What hitch do you use for towing your camper?
What's the difference between the LBZ and the LMM? I'm looking at a 2007 GMC 2500HD with the LMM and I would like some input on it. Thanks
Do you have to tune your vehicle after the delete? Do you have any engine codes that pop up after the delete
Do you think some Exhaust Wrap alone or along with the shield would help?
I think it would
You got a sub from me, I bought a trailer from the same dealer (same location) my 2022 Silverado hd duramax should be here soon.
Small world
What's your opinion on the Banks Duramax stuff?? I'd be interested in that only bc not much content other than from Gale himself.
Do you do these installs for a living? I have the identical truck including that Equalizer hitch except I had them make me an extended shank so i could lower my tailgate. What's the total damage for the install including parts and labor? You made it look easy but it's beyond my range anymore as I'm 77 years old.
That’s why they got all those heat shields down there
Temp is that big of a difference on the longevity of the engine?
but did it make the truck any more power or better your mpg?
We would all like a shop with a lift but most people would be doing this in the driveway, I know it was harder for you but thanks for not pulling the cab 👍😁

Hey truck master. Been considering a colorado with a 2.8l 4cyl Duramax. Do you have any experience with them? If so any thoughts?
Sorry if I missed it was that manifold EGT’s?
I’m going to save this video so when the time comes.
I’m actually posting the full install video on my other channel truck master garage
I think for the average Joe this is a lot of work especially without a lift in their garage. It took you 20 hours and then some. So at $1500 plus change and labor to save a little bit of fuel. What is the payback time to even break even? My 05 GMC Duramax has stock equipment and 240000 miles on it and I pull a 10,000 lb. 5th wheel with it. No issues.
I’m thinking it will pay itself off in a year
Getting ready to do my lly, got all the exhaust parts, getting the pusher Y bridge, hope my results will be similar. Great channel, keep up the great work!
What MPGs are you getting after this?
If you were not going to tune and are only looking for MPG gains, which emissions complaint upgrades would you do?
Another question; if a few simple bolt-on parts help with Heat and Fuel Economy why doesn’t GM and other car manufacturers do this stock?
I got the same kit for my LB7 for $899 throttle response is so much better.
Definitely 👍
What egt’s do you see?
@@marka1712 I'll let you know when I find out had them put on and sent truck for trans work drove it a short time never put get gauge in
Something I want to do to ly LML. Among others, LOL.
I have a 2006 kodiak lly. I have heard that doing these mods do next to nothing on them, as they are detuned from the factory and already have different pipes then the pick up trucks. Do you have any experience with mods on the medium duty trucks? By the way, I only see max 20 psi on my boost.
So I’ve got a question to Truckmaster. I’ve got a 17 l5p and I want to swap in manifolds but I don’t want the egr riser on it. I am tuned and deleted and have up pipes. I was wondering if you knew or anyone know if lml manifolds would work as a replacement?
Not a v8 diesel guy but nice truck bro 👍👍
What is that display on the dash? Who makes it?
How much did the kit cost mine is the lb7
3 Shirts and a Key Tag Brother
Thanks 🇺🇸🇺🇸
@truck master does anyone make manifolds for the L5P without the EGR as my truck has lost that already?
Not sure but I think they have blocker plates for the passenger side
AMAZING and you also have to wonder why the engineers never did this at the factory.
I always wonder that myself
Somedays i thinks its because they don't know what they are doing.
The reason why is because they are optimizing the use of those parts for different applications and options you can get on these trucks. If you can use the same part on twenty configurations, you can save a pile of money not only on the part but also on tooling at the assembly plant level.
They need to make money off of replacement parts. Make the truck too good and that won't happen, so they make it good enough. That's my guess.
Id love to see how far an l5p can get pushed while being emissions compliant.
You can push far, it's just not going to reliable and it's going to regen everyday
You should have got the truck on the dyno before and after.
