How To Install L5P Duramax Manifolds, Up-Pipes and Down Pipe!

[@javiera3229]

Just did my manifolds, up pipes,down pipe and wherli fab high flow bundle kit and cp3 conversion on my lml. It was a nightmare but sure dam worth it!! All I hear is music out my dual 5 inch exhaust pipes Your vids are much appreciated man!

[@Johnnyfreitas1]

I can’t find a video of anyone pulling the cab off of one of these newer model trucks. I think that would be the way to go. Pull the cab pull everything off install everything put the cab back on done deal. That’s the video you should make pulling the cab for 3500 2021 truck pulling off the DPF turbo the downpipe all that crap and putting it all back together with all the new improve products that race trucks need

[@joeb.8625]

The dp took how long to take out?

[@justinmalburg806]

would it be any different installing this kit on the 2020+ l5ps? Cant find anything online of this being installed on the new body style

[@daltonknicktv2565]

Wondering the same was it the same process?

[@andrewpiercy1023]

Other than price, This is an additional reason I refuse to by another duramax. Still own my LBZ to this day from 2006 and runs like a top

[@Ruffles206]

You can imagine this truck with nice high flow plus delete wow will be super fast 💨 and low great job 👏🏼 man

[@jarrettfails1567]

The ppei manifold and up pipes on ur truck master diesel web will fit a 2016 durmax?

[@benjamin5224]

Would changing my downpipe make my truck louder? Installed a 5 inch straight exhaust and it's still fairly quiet.

[@nojam3562]

Did it?

[@benjamin5224]

@@nojam3562 I never got around to changing it before I sold the truck. But yea supposedly that's how to get it louder.

[@nojam3562]

@@benjamin5224 I just tuned and deleted my 2019 and it sounds maybe a hair louder then stock tbh. hoping a down pipe will do it going in Monday

[@benjamin5224]

@@nojam3562 I'm sure that will do the job 👍

[@jorgebarragan4202]

Did it do the Job?? Did it make it louder ? Have you changed out the intake air horn and intake ?

[@joe0813]

im a tech at a GM dealer and thank god im not the diesel tech 🤮

[@jalbers]

Would have been cool to see you start it up and drive it a bit and give some feedback on any noticeable improvements

[@PabloValenzuela-mh8zt]

Where did you get those bolts? Im in the process of doing the manifolds and up pipes

[@Ruffles206]

Hey you have any updates about this? Try to buy this kit for my 23 L5P I can’t found in your website, do you have any video about the sound 😊

[@50calprepper]

With mine being “ liberated “ this process should go a little easier 🤷‍♂️ Have manifolds and pipes ordered, I’m debating on the rds 64mm or the stealth 67. May wait to do all at once, I know when I had the turbo off to give it full bald eagles, I could reach the top of up pipes no problem.

[@michaeltaylor2825]

Do a video about a 3.0 duramax. What's your thoughts on a 3.0 duramax?

[@TruckMaster]

Not a fan but it would make a good video

[@CryptoKingpin777]

How have they been holding up?

[@truckmastergarage9944]

Still going strong

[@charlesswearengin2404]

I enjoy your channel, watched you from the beginning. This is something that I'd really like to do to my 08 but I'm sure I'd end buying a lift. And that's in my budget, Awesome Content Josh.

[@truckmastergarage9944]

Thanks 🙏

[@michaelmatney4907]

Hey would you be interested in doing a 2019 Chevrolet? Hahaha?????

[@winssern]

I'm doing this job right now! How did you get to that oil dipstick screw?

[@ChristopherMoye]

I did this same job on my 06 LBZ years ago and will be doing the same on my 2020 L5P this coming spring. Really wish you would have let us have a before and after listen but thanks for showing us how its done. Edit: I will be doing the upgraded intercooler pipes at the same time.

[@kalebsmith2349]

Did the manifold and up pipe on my lmm and no bolts snap even the studs came out. Guess we don't get the salt like you guys do.

[@Jc-bo1uu]

If it was me I would have raised the cat at least 6 to 12 inches are so. That would’ve made it a lot easier. Nice video.

[@arturomunoz7113]

Where is the video on how to install the up pipe I don’t think he could actually do it

[@darylsparks-sparksautomoti6066]

what's the freakin point?

[@wiboatrentals]

I watch all your videos! And your patients is awesome step by step and you have to film the whole time ! It’s awesome !

[@beausmith3900]

I have an lbz I have been wanting to do this ppe kit on, now that you have it mastered maybe you wanna do mine? What did you think all done? Was this worth it?

[@joeb.8625]

So does the old dp have a built in cat

[@Mantijohnson]

Is the process the same on 2020 + l5p

[@casperhoss2952]

Great job! Earl must be so proud. If you ever get frustrated always think WWED, what would Earl do? Thanks for sharing brother.

[@TruckMaster]

thanks Casper 😂👍

[@casperhoss2952]

Your time and talents are really appreciated. You help folks understand how to do things to improve their trucks. Please keep the videos coming and thanks again for all you and your wife are doing for us.

[@drivebyracer14]

Great video. For anyone tackling this job, here are a few additions.. Up-pipe to turbo pedestal bolts, work them back & forth to prevent breaking. It was well worth the time to pull all the exhaust studs if you have an E7 torx socket or something that will work, manifolds come out without pulling the shock. I pulled the driver side manifold before the up-pipe and had plenty of room to fish the up-pipe out instead of snaking it through the passenger side. PPE hardware is always a gamble on quantity & quality, plan on a trip to the hardware store. Kit does not come with egr pipe gaskets, local shop says re-use them, down pipe donut too. (jury is still out on that) Thanks again Truck Master for the video, alot of good info and visuals!

[@paj467]

was this on a deleted truck ?

[@CFarmer]

Great video!

[@michaelsites1498]

Great video for sure but I would have to of did some kind of coating to make sure it not only lasted forever but it stayed looking great too!!!!

[@MWR-lg9qp]

You sir are a madman. Great video, thank you.

[@EliasStonehocker]

Shoot didn’t know you’d posted this! Awesome!!

[@davidparizek6741]

Josh, did you install all of the heat shields back on?

[@truckmastergarage9944]

Honestly no 😂

[@davidparizek6741]

Thanks Josh

[@Jc-bo1uu]

How is that work out for you? I have a 2019 L5P too and I was thinking about doing this with my truck.

[@lawrenceheinz2679]

Another awesome video!

[@outlawedryno7593]

Hey truckmaster i bought a 06 gmc Sierra with the LBZ duramax i have some questions for you when you get a chance

[@nealhoskovec8352]

I was woundering where you guys are located at. I am looking to delete my 2019 gmc.

[@ramonpacheco4753]

What year was that truck, im having rubbing issues with steering shaft on a 17 gmc L5P i need some advice

[@bradleyhodges451]

What’s the part number for the this kit you did cause I’m gonna 2021 AT4

[@dmaxman321]

I’m in the process of picking up a 2017 l5p and I don’t think I’ll be tackling this.. that looked pretty horrible lol, I’m super curious of the difference in egts and your overall impression of these products tho. Great video 👍🏻

[@TruckMaster]

Thanks! Watch my other channel I did a full egt comparison 👍

[@drumoubray6246]

Did you reuse manifold studs and up pipe bolts? The kit I bought only had 6 manifold bolts and some heat shield bolts. No up pipe bolts.

[@cjrod9443]

@truckmastergarage does the down pipe need to be replaced if your doing a dpf relocation?

[@johnbenoit6133]

You said you had the parts for any year Chevy. I don’t see anything for a 2020

[@Scbeck]

Fuel lines on the drivers side not trans lines. Going through the process of doing ppe pipes and manifolds on my lml right now. I had to remove the trans crossmember bolts and jack it up a bit to slip the drivers up pipe between the cab and engine

[@Corey497]

Anyone recommend a shop around Buffalo NY that can do this for me?

[@west2718]

Since you have had this installed for a while did you see much got mpg increase?

[@Espinal_424]

so by doing this, are you now deleting the truck?

[@MARINE1FORCE6425]

Did you have a hp and tq increase when up upgraded those pipes?

[@traddhankins]

"Be very careful with this" - throws the heat shield across the garage

[@King__Casey]

is all hardware included in buying the kit?

[@porksword4]

Man I just got news I have a manifold stud broken an they want to replace them all at the dealership but want 4000 to do it. Haven't been in such a low dark place in a while I'm laid off and told them to just throw it back together.

[@travisreyes5964]

i’m sure you go it figures out by now, but pro maxx sells a template specifically for drilling out broken manifold studs. i got quoted the same price and said f that and bought that kit and drilled the stud out myself

[@scottcote8808]

Do u have to delete to install a new exhaust on the l5ps

[@tater0909]

Was all the effort and work worth it?

[@ricktryon3785]

Do you reinstall the heat Shields on any of them?

[@andrewt248]

So. Many. Heat shields.

[@edwardglaze5667]

Thx very helpful

[@brandovillasenor8049]

With lowering the egt, won't it cause problems with the emissions system?

[@Kenny-ir4pr]

Any answer to this question? I'm looking install up pipes, downpipe and manifolds my 19 lp5 that is married to a 40ft gooseneck. Not looking for it to cause problems

[@curtisgillard3626]

Thanks for doing this video! Very much appreciated. My 18 Silverado Dmax has a major exhaust leak back there somewhere, so it appears this same work is in my future. I understand pulling the cab is the preferred method. It seems you might have experience using both methods cab on, cab removed. Question: What do you think about lifting the cab just a few inches without full removal? I'm wondering if even 2 or 3 inches would improve access quite a bit for someone without a hoist.
