UP PIPES, DOWN PIPE & MANIFOLDS by Duramaxtuner.COM

[@eraser1175]

Nick, thanks for your videos bud. They are short, professional and to the point. They answer a lot of questions I have about what parts are necessary for performance upgrades, Thanks again.

[@louiebanditoa8583]

with these upgrades will it help on fuel and is it safe to install these into a high mileage duramax

[@reminoel483]

No reason it wouldn’t be safe on any truck.

[@daleleis5563]

Who manufactures the exhaust manifold and the up pipe? You failed to mention that

[@duckco1]

I like how he says in one sentence how terrible the design is of a up pipe or the manifold then in another sentence talk about how great OEM quality is. But I still love this guy very knowledgeable and informative knowledge is definitely power and I've gained a lot of power from this guy

[@Wretched2JZ]

True!

[@Cliffdowgy6er]

Hey duramaxtuner the bellows on my stock up pipes are cracking and leaking I don't want to buy aftermarket ones due to the $500 price tag if I pull my up pipes off and get the bellows to fix the leak could you tell me the diameter of the up pipe

[@GTOGregory]

I would like to know if these parts were used on the LML with the new Stealth 64 VVT turbo?

[@joeb.8625]

So I just sub'd, I travel a lot for work I'm a Travel RN and I tow with 2018 Duramax 16k quite regularly across the nation currently in Southern Oregon. So my question is, in short of deleting what options do I have to add some hp and tq without going piggyback? Are there tunes that can be downloaded to ECM that are safe and reliable? Maybe like high 400s whp and 1100tq+ is it possible without a piggyback?

[@Duramaxtuner]

We have custom tuning for your truck actually. You install a new Unlocked ECM and then flash the tunes with your laptop and the hardware we send you. Take a look here: duramaxtuner.com/diesel-tuning/chevy-gmc/l5p.html or give us a call (815-568-7920).

[@6806goats1]

Good stuff Nick. Think I remember reading some of your forum articles back in 2007-2008 when I was hot and heavy into learning more about my 05 LLY. Glad to see you're making these videos.

[@ismaeltorres8848]

An 08 Silverado duramax I love it already only had 3 months but it’s stock I wanna upgrade it for heavy towing or just make it fast

[@NYC54Studio]

Hi Duramaxtuner! Thank you very much for your good explanations about the exhaust system and how it works right the flow of gases. I appreciate!! Greetings from Spain, Barcelona :)

[@Mr.BigweldNBTX]

I"m looking to get your exhaust manifolds and up pipes and have been watching your videos great stuff by the way. You mention that the factory bellow on the up pipes is a weak point which is exactly where my issue has been. I see that you have a beefier up pipe but still retain the factory design with a bellow, will this be an issue in the future as they are prone to blow out there? I've noticed others make a solid pipe all the way up, whats the difference? Still learning a lot about diesel tuning and love my duramax, any guidance would really help. thanks

[@myrkobalaban8571]

Are the exhaust components 50 state legal?

[@Upsidedownfoodpyramid]

How much does it cost to install that? If a person was to do this, do you have any real world numbers with and without tuning with everything else stock? I guess what I am asking is if all I’m looking for is lower EGR temp, better passing, increased MPG and less DEF consumption will I see enough gains by this without a turbo upgrade and keeping it completely street legal?

[@Upsidedownfoodpyramid]

Around town without a trailer and towing in the mountains in high elevation. In my opinion there isn’t enough good videos about this that makes me believe it is worth the money to upgrade air intake system in my 23 L5P Duramax 3500 and up and down pipes. I would love for you to sjow me and the diesel community the real world numbers for my needs stated in my other comment.

[@chevydmax1000]

Hi Nick, I have a 2016 LML. Are all of these poorly designed pipes and manifolds used on my LML or did some of them get better from the factory? Thanks

[@richardmaxwell3828]

I love these informational video and the downpipe is only a pain with a cab in the way lol

[@zhongxina5595]

Not really

[@dannyrbailey]

The ppe manifold has smaller openings does that decrease flow compared to the stock manifold with larger openings?

[@tylergist8557]

I need that upgraded down pipe! I've bought 2 different down pipes they dont make them to clear my upgraded manifolds and up pipes. Both downpipes ive bought hit the up pipe before the flange is flush with the back of the turbo the gap is probably 1/4 to 3/8 of an inch

[@tylergist8557]

That's after I've destroyed the first downpipe its almost completely beaten flat. I still need 1/4 to 3/8 of an inch to get the flange of the down pipe to be flush with the back of the turbo so I can bolt it on but this will never work. Also my truck is an 03 lb7

[@Duramaxtuner]

@@tylergist8557 Give us a call our guys can probably help you out. 815-568-7920

[@pascalkobler1020]

I had the same issues, when i installed my ppe manifolds, up, and downpipe. I write ppe, and they answer: dangle the downpipe with a hammer, until it don't contact the uppipes. That's high quality - made in usa 😑. Than i order the flo-pro downpipe, it was better, but i also have to deform it to fitment. For reserve i had a mbrp downpipe at home. Butni don't know if this fit better, it's hard to get them pipes in and out, once istalled the flo-pro i wouldn't get it out to try the mbrp.

[@gerardorodruiguez5928]

Im having this issue rn. Do i just hit the DP until it gets?

[@Blue_Collar_Hunter]

Would the down pipe do anything beneficial for a stock LML?

[@Duramaxtuner]

Unless you have a bigger turbo or twin turbo kit I would not imagine it is going to make a big impact.

[@Blue_Collar_Hunter]

@@Duramaxtuner alright. Problem solved get a bigger turbo so I can do the down pipe. That's a great new project.

[@ericgallegos4874]

How much for the set up ?

[@jamesmacklin9735]

why are the ports on the upgraded manifold smaller than stock?

[@mikz86ta1]

So stock LML would benefit from some of these? Like just quicker spool and less towing EGTs? Or only benefit is pushing 450/500HP?

[@Duramaxtuner]

Custom tuning would get you more than manifolds and up-pipes.

[@archielee7434]

@@Duramaxtuner I have a 2013 GMC with the 6.6 Duramax with 145,000 miles on it. It is still stock except for the exhaust which has been deleted. I am very concerned about the CP 4 injection pump. If I add a lift pump (FASS) will the CP 4 pump still be a reliability problem with this motor? Will this keep me from having to repalce the CP 3 pump with a CP 4 as this loos to be a pretty extensive procedure to perform. I am 64 years old and had to retire on disability due to having to have the whole lower part of my back fused together with rods and screws. I am not as flexible as I once was and have pain from moderate to extreme depending on what I am doing. I bought the truck in 2015 with 23,000 miles on it before I knew the CP 4 pump was a reliability factor. Due to being retired, I wanted something to last as long as possible. I run Amsoil Signature 15w-40 in the motor, Wix filters in all locations, and add Amsoil fuel treatment in the fuel at every fill up. I try to buy all of my fuel at the same station (Murphy Gas) unless I am traveling...which is frequently. The only thing I have pulled with this truck is my 20 foot bass boat which is usually less than 20 miles round trip, however I do work with the local High School and pull my boat once or twice a month to various lakes throughout the state of Georgia and South Carolina. This June I will be pulling my boat on a 3000 mile venture (from Clark Hill Lake on the Ga./SC border to Lacrosse, Wisconsin) for the High School team to fish in the Nationals. Thanks for all your help and advice.

whats your opinion on soflo diesels 5 inch exhaust to 8 inch dual stacks 5 inch down pipe to straight pipe then to 8 inch tacks

[@pyrocrew13]

would that be a good addition the DT520 power pack on a stock truck or is that more geared to the over 500/600 power ranges?

[@Duramaxtuner]

It is geared more toward the 500/600 trucks. Also trucks that are running aftermarket single turbo's.

[@HPL5P]

Do you have manifolds available for the L5P?

My question is does the lb7 up pipe fit the lbz manifold

[@Duramaxtuner]

Yes

[@ismaeltorres8848]

Hey we’re can I order all that I have

[@fredbrinson6348]

Where can I get exhaust medicals

[@JNH123]

Do you have all that for the L5P yet?

[@Duramaxtuner]

We would not suggest it. You would get more from doing an L5P Tuning package. Also, with emissions equipment heat is not the enemy. You need the heat in the exhaust to efficiently burn off the soot in the DPF. duramaxtuner.com/tuning/l5p-tuning-package.html

[@jayrichmond2325]

Hey I'm a newbie to diesel, how and where do both up pipes meet to enter the turbo? Thanks

[@ralfie8801]

They both bolt to the turbo pedestal, right under the turbo.

[@papascrags7930]

I've got an 2006 LLY duramax with an AFE intake, and a 4" Diamond Eye exhaust. If I install a downpipe, is getting a tune required?

[@thomasfrye1710]

04.5- 05 is lly. 06-07 is LBZ

[@gbarker8]

@@thomasfrye1710 not true I have an 2006 LLY as well www.duramaxhub.com/duramax-vin.html These show models based of Vin so this statement everyone says about all 2006 being lbzs are false. Some are, some aren't.

[@thomasgriffith3747]

@@gbarker8 I know this is an old post but if anyone is reading this, that char is not accurate. I just bought my 2006 GMC 3500 Duramax 6.6 LBZ. It was manufactured in 10/2005 and had code "D" (LBZ) in the VINs 8th position

[@ismaeltorres8848]

How can I do that

[@Jackson-iu7mw]

The manifolds, up pipes and downpipe, how much hp would that add on an 600 hp duramax

[@ronmower3694]

25-35whp

[@richflynn1550]

What's the price for all three plus install on 2016 Duramax?

[@Jimbofree93]

Rich Flynn I’d say no less than $2000. The parts alone are around $1500

[@Youdaboob]

south GA diesel not true, I just bought the ppe manifolds and up pipes new on ebay for $480

[@robertjames913]

Why can't these be added when emmisions are in tact?

[@Duramaxtuner]

Great question! The first reason is that for emissions equipment to work you need heat in the exhaust. Larger up-pipes and manifolds will generally reduce heat in the exhaust. The next reason is the lack of benefits for an emission equipped 600 RWHP truck. Over 700 RWHP builds generally have the most to gain with up-pipes and manifolds.

[@ThatTURK1]

What do the bellows on the uppipes do?

[@Duramaxtuner]

They allow for expansion under extreme heat. Those occasionally become corroded and fail. At that point, some owners opt for aftermarket up-pipes.

[@jcporosity4764]

Those welds on the stainless steel jesus chris...

[@joegelencser2571]

Is awesome! but When you have pressure?? you always have pressure with a Turbo Those parts you're showing are definitely better but it doesn't really matter because it's about the pressure the Turbo makes just think of a balloon is it any better with is it worth inflated to full capacity or 10% not trying to be an idiot but don't lie to people and God-bless

Very informative. But this NPC is in desperate need of an update.
