I really appreciate it Kyle

[@ashtonallen4318]

Recently bought my first duramax... your videos have helped me tremendously to increase my knowledge on these trucks love the videos

[@TruckMaster]

Thanks 🙏

[@danieljones8587]

A big thank you for your video! Just a couple of pro tips: You will need a 3/8 torque wrench that pivots (Harbor Frieght ICON) and at least one extended 8mm hex head socket cut to size to get all the hex head bolts properly torqued to "42" POUND FEET not 50. You are bolting into aluminum heads, so be careful. Remove your front tires. I read another comment about jacking up the engine and trans... That's a great idea. The frame rails are so close to the manifolds that it makes it hard to get to get to the bottom bolts.

[@brannonfrost4286]

Sir, I've seen SEVERAL of your videos lately.I can't thank you enough for the help you're providing us viewers.I was afraid to do much myself since my experience with diesels is very limited versus gas burners.Thanks to the step by step,in depth details your content gives,I'm now confident I can save money and get to know my truck much better by doing more upgrades in my own shop myself.I appreciate the effort and time you're obviously taking to help us learn. And also,more than all,I salute you for the freedom we enjoy.May GOD bless you and all who help you, especially your wife.

[@TruckMaster]

Thanks Brannon

I’ve been getting into watching a bunch of informational videos about Duramax & Powerstrokes. I like yours the most because you’re just aDuramax guy. One of my best friends is a classic Chevy guy. I remember the first Duramax & Allison I drove 20 years ago. Super impressed then & they’ve only gotten better across the & board & technology is skyrocketing. You’re the most down to earth, diesel guy I’ve found. And honestly nobody else has a Wifemax & her truck is cool too. Tomorrow morning I’m getting the muffler & flapper valve deleted on my LTZ Silverado. I have a Mustang too but the Silverado is way nicer to drive everyday. Keep up the good work

[@TruckMaster]

Thanks Norman and good luck with everything

[@tinochacon4937]

I got the exact same kit. I got one side all out just need to remove the driver side. I’m glad I also went with the Ppe down pipe. Maybe a little trick for anyone tackling this not so fun job is to remove the two trans crossmember bolts an put something to distribute the load over a jack under the trans pan and jack it up until the top just touches the floor and get yourself an extra 1-3 inches back there. Makes a big difference IMO as any guy or girl knows a little extra in the right spot means a world of difference! 😉 Happy New Years from KS 👍🏽

[@B.O.M.BHellFire]

Huge thanks go to you I got a 2003 lb7 that I'm building. Your videos have been helping me tremendously. I'm defiantly getting this set up I run a hood stack on my truck always worried about my heat messing up gaskets and wire connections.

This is just a thought I like using anti seize on manifold bolts as well as other ones just a thought. I know other people are making comments about your heat source you can put a coil inside your garage off your out side central boiler it's like having free Heat.

The ppe are the same as dmax store max flow. I have pictures of both side by side, there literally identical. Up pipes are exact same and they can be swapped

They are probably made by the same company, many aftermarket items are rebranded for multiple brands.

Last mod before I sell my LBZ. Thanks for all the help with your vids. Ill miss em for sure!

[@Magucci13]

When I first bought my LLY and started learning about Duramax motors (and diesel in general). I noticed just how cramped and small all the piping was, especially the exhaust manifolds. I always thought to myself I wonder how much more power these trucks could make just by flowing better. Glad to see they actually work. I bet you'd notice and even bigger difference after a stroker pump and wind her up to 4k

[@jakerose992]

They make a stud remover folks! Works like a charm with a half inch breaker bar

That down pipe bracket is prone to breaking off. I chased a rattle for days before I finally found mine had broke and was rattling against the down pipe. After a search on the groups I found a ton of people have had the same issue.

Crazy how low your boost is with your high flow iit and new manifolds/up pipes. Mines all stock. Deleted tuned and s&b intake. Ive hit 42lbs boost in tune 5

[@sethholsopple3802]

Great video happy new year to all.

[@jimschweitzer4440]

Appreciate all the install videos! I have replaced the down pipe and installed a 4” exhaust and now I am considering the manifolds. I’ve seen the PPE and recently your HSP manifolds. Still deciding which way to go. Cooler EGT and better power is always a plus. Can you explain why only the passenger side exhaust manifold goes to the EGR? Why doesn’t the drivers side… I still run the EGR as I do not want reprogram the computer. Again Thank You!

[@tyler1671]

Thats stupid to do dude

[@johnking1164]

Hey Josh thanks for your videos they help a lot. Love the detail you put into your installs. I have a question. Back in February of 2018 you done a video for a manifold and up pipe. I was wanting to install the same parts but could not find your part number. I have an 06 GMC with the LBZ. I have 4” exhaust a single stage tune, the pcv delete and egr delete. It has 370000 miles on it. My bellows cracked on my up pipe. So I wanted to put the same thing you installed on mine, I do have a new 3” down pipe to install at the same time. Mine is an everyday driver and I don’t do any racing or very heavy pulling. So would appreciate the info on what you used unless you recommend something else, thanks in advance!

[@DEFBOY35]

These suck so much more to do on the lml frame with the control arm mounts being above the frame. Lol. Had to watch again to see what the trick was for the bolts. Need to hack up an Allen key now!!

[@jadebrecks]

Surprised you didn't show off how crushed the driver side manifold is from the factory. Flow is a good thing! Compliments the intake piping flow better!

[@beaversstumpgrinding3352]

A stud kit on the new pieces will make servicing them easier down the road...or trail.

[@cdsmit27]

What's a stud kit?

[@duramaxdad]

Replacing the new Allen wrench bolts with studs and then nuts to hold the manifold on.

[@KoltFin]

Don't you have a probe in the wifemax? You'll be able to compare egts then. for the test pull the trailer on a mile long road with cruise set at 65 or so then you'll have a repeatable loaded test.

[@TruckMaster]

I do have one on the Wifemax not a bad idea

[@markaszmann9836]

Have you ever considered wrapping your exhaust manifolds and up pipes to Make your Turbo more efficient

[@jerryeasterday4044]

Just what make is your front bumper, I like the profile of the bumper to the gm truck. Thanks and keep up the great information.

[@AandWProductions]

The only mistake I saw (and maybe you did and didn't show it) but you didn't put any anti-seize on the bolts. Seems minor, but it makes things so much easier if you ever have to tear things back apart. I did these when I did my HG in my 05. I had the engine pulled so my job was a lot easier. Which was good, because one of my studs broke off in the head.

[@keng1197]

Put them on mine about 6 months ago 😉

[@DEFBOY35]

Have you added an egt probe since installing these? With the coating I’d think the more fair temp gun reading would have been on the up pipe just as it exits the manifold. But either way. That was quite the drop.

[@beyondthecutcreations9391]

I'm stuck on the bottom 13mm on the driver side up pipe at the bottom of the Turbo pedestal. I've got everyother bolt loose. Now I could only get a 1/4 drive to fit, Broke 2 1/4 drive ratchets and a 1/4 drive breaker bar. PB blaster for a week now, don't want to break this bolt like one of your other videos, I'm about to try and heat the up pipe around the bolt with a torch, any other suggestions? I'm doing the Profab headers and up pipes, and the high flow y bridge kit from wcfab, cp3 10 mm stroker, fass 165 for this part of the build.

You do realize that those manifolds are ceramic coated, taking the temperature on the outside without a egt probe will not give you an accurate exhaust readings. You need to get an egt if you’re going to make recommendations on a purchase.

@Truckmaster How did the exhaust port size look on the new manifolds?

I was curious how the PPE manifold ports compared.
