Duramax LB7 5" MBRP turbo-back

[10ARios]

They do sound like a 7.3 but just a bit better sounding.. can anymore tell me wtf is the diff between LB7's LBZ's LMM's??????? They all sound diff too

[seth1913]

@10ARios lbz and lmm are the same i think but both the lbz and lmm have different turbos than the lb7

[uberbadnoob6699666]

does any one else think they sound like a 7.3 powerstroke i think they do holy crap

[thelockablewalnut17]

What size is that exhaust tip?

[mulletmasher]

Ive never been able to hear any turbo on any LB7 motor ever until this video..can you still hear it with the straight pipe?I have a 4inch straight pipe on mine, do you think it could be from your 5" versus my 4"?

[lukas100709]

love this sound just went cruising in my lb7 and i can't stop flooring it.

[RACER013]

kinda sounds like a cummins

[uberbadnoob6699666]

this thing idling sounds like my 7.3 weird

[playaz4uus]

My LLY sounds about like that 4" MBRP no cat or muffler 4" down pipe also soon to have 5" with single 8" stack

[turbopunch]

@playaz4uus you should here your turbo a bit better through yours though correct?

[mulletmasher]

@playaz4uus

Really? Even with the different turbo? no whistle or anything? thats pretty sweet!

[8300JohnDeere]

Is that the MBRP tip also?

[ShowtimeStables66]

so, cat or no cat, dpf or no dpf? not for sure if this model has a dpf but anyhow

[travisxxx23]

@ShowtimeStables66

The lb7 model of the duramax didn't come with a dpf or a cat.

[ShowtimeStables66]

so, cat or no cat, dpf or no dpf?

[jackass22x]

best sound ive heard yet

[POWERSTROKE250SD]

Get a Powerstroke..

[strumem90]

@POWERSTROKE250SD BAHAHHAAA...

[MaverickRIDDLE]

can you get a fresh video up since you have taken the muffler out please?

[555222444999]

is that a clamp on tip and r those street tires. thanks

[texasboy2471]

thats sounds ugly fool

[bic1457]

pisses me off when ppl down the duramax because its isuzu. so what gm's owned isuzu forever and its a gm design

[strumem90]

@bic1457 its also made in America witch a lot of other people seem to get wrong too eh..

[MaverickRIDDLE]

what year is this truck? i hav an early 2004 LB7 duramax and am trying to decide whether or not i want five inch or 4 inch... i had 4 inch with a 5 inch tip on my 01 and it was awesome... i want whichever one is loudest...

[555222444999]

r those street tires and is the xhaust made from T409 or aluminizd if its aluminizd hows it hold up 2 the weather thnx

[ragebowhunter93]

sounds straight piped now

[MsSteelersfan86]

hey man i like your video alot. i am a huge duramax fan!

my dumb ass friends think they suck, but i dont i love them tell me if there is anything wrong with them?

[CrudeOctane]

There is nothing wrong with them!

[Jacksonkellyfreak]

the only thing wrong with the duramax was the injector problems they had on the lb7. the lly engine i belive had no issues

[chevy490]

@Jacksonkellyfreak and some had a transfercase prob. but there dam good trucks

[Jacksonkellyfreak]

@chevy490 Ohh yea, i remember that now.

[555222444999]

I think this is the best soundin LB7 on youtube how come this one has a deeper tone and then some other LB7s wine more

[NROBLEWC]

truck sounds good

[MegaDirtymax]

Love the sound

[DuramaxDiesel2500]

nice sound the lb7s sounded awsome:) im starting to like to 5 inch exhaust systems more now, and btw why did u take off ur exhaust?

[monserd777]

why is there a bunch of shit flying around by ur front end

[volumejunkie]

You know the motor has a fan right? There are leaves on the ground. The fan blows the leaves off the ground.

[jdshaq]

wow that guy that asked that question is a idiot lmao

[cobra97man]

man do i love that sound

[555222444999]

what kind of tires r those. that xhaust souds awsome

[volumejunkie]

they are bridgestone dueler revo 2's. I got about 30k out of them. thanks

[dieselvsgas1]

thats mainly stock lol

[Eorvig]

turbo back? i know its hasnt got a catverter on it...turbo back?

[grangeroo]

Is that one built by Detroit?

[saosurvive126]

hahahahaha no Isuzu. Why would GM use an American diesel? haha.

[FORDGTFANATIC]

???? duramax's are made in America dip shit

[saosurvive126]

Yeah true, Dmax's are made in Ohio....by Isuzu, they're Japanese. Thats just the way it is guess it doesn't matter... Toyotas, Hondas, Subarus are made in the US... they're still Japanese. American cars are made in the US using US, Mexican, Japanese and European parts.

[FORDGTFANATIC]

and what kind of diesel is your favorite...powerstroke???

[saosurvive126]

Idk. I'm a Ford fan. I like the 7.3. The 6.0 sound awesome, but weren't very great. 5.9 Cummins are cool. But I don't like Dodges much.

[Alacranchorrudo]

I'm ready for the new 6.7L powerstrokes that are gonna come out

[pistonsman12]

those are gonna be built in Mexico

[Alacranchorrudo]

I heard they were. Hope it doesn't let down 4real.

[pistonsman12]

I read it a couple of month ages in diesel power magazine

[orbitofdoom16]

Im glad that someone realizes that just because a car is made in a country, its from that country, and benifits their economy more that the parent company

[chevy490]

actuly gm owns 49% of the plant which is more than isuzu. but it is a joint effort non theless

[MaverickRIDDLE]

@FORDGTFANATIC if the first number in the VIN is a 1 its made in the USA, if its a 2 its made in Canada,and if its a 3 its made in Mexico

[MaverickRIDDLE]

@FORDGTFANATIC if the first number in the VIN is a 1 its made in the USA, if its a 2 its made in Canada,and if its a 3 its made in Mexico

[kilo6490]

@MaverickRIDDLE ??? ALL duramax's are made in Flint Michigan. lol

[MaverickRIDDLE]

@kilo6490 and if u notice the first number on a duramax vin should be 1

[SparkZ1420]

the duramax is made in Ohio

[SparkZ1420]

its built in Ohio, jackass

[saosurvive126]

Thanks, I didn't know that. It hasn't been said several times in these comments...

[99chevzr2]

thats a nice sound!! I ordered up the 409 stainless system in the 5", just waiting for it now

[jorgtrucking]

Thats a sweet sound! I really want a Duramax to take to college. I found a few lb7s that I like but i've read a lot about massive injector problems....Has your truck had an injector issue? Or have you replaced them? I want a duramax but if i have an injector issue after I buy it, I wont have $4,000ish to pay for injectors... Thanks for any advice/help.

[truckmedic1775]

if you dont mind me asking im looking to do something similar and i like this sound, what did you do and how much did it cost?

[ragebowhunter93]

need some new tires. get some mud terrains haha

[97vortec350chevy]

Those are the Bridgestone Dueler A/Ts. They last a while, Ihave had mine since 40k miles on my 1500 silvy and I have 83k on it now. They are good tires for occasional off road but yes M/Ts would be niiiiice esspecially with that sweet ass DMAX

[txsurfer32]

truckaholic, you can just say it came stock without one. i have an lb7 and it came with no cat

[kid4king0097]

cool.

[oldredmuddin]

needs biger tip

[cfundevil]

thats wat she said

[truckaholic]

cant u get busted of not having a cat? i was thinking of doing it to my 07 lbz

[volumejunkie]

LB7's don't have one.

[truckaholic]

lb7's dont have a cat!? lol are u serious?

[volumejunkie]

Yup. No cat, no egr on the federal emissions trucks. The California emissions trucks have them though. Most dont.

[truckaholic]

dame. i have a cat on my lbz and i hate the fact that i have it

[555222444999]

@volumejunkie when u say California emissions trucks does that mean only the lb7 duramax's only in california have cats and egr if not what r u talkin about

[Derekltr450]

If I didn't know any better this thing sounds exactly like a cummins. Sounds good.

[nemoswint06]

If I didn't know any better I'd think you're an idiot, that sounds NOTHING like a Cummins.

[jpg8402]

I have to agree, they both sound good IMO, but they sound nothing alike. LB7s are by far the best sounding Duramax, nice truck man.

[0919dodge2500]

sounds tight but only thing is i watch the video at 17seconds and look by the front tire its like the exhausts leaks up there

[volumejunkie]

You do know all vehicles have a fan in front of the motor right?

[quidew1]

wish my lbz sounded like that! that should change here soon as im about to get liv

[diesal41989]

how does she pull as far as alot of weight..im not sure how much you pull but i usually tow about 7-8 thousand depending on what tractors i use........mine is tuned also with a turboback exhaust and it sounds just like yours...their sound in unbeatable. is yours a crew cab or an extenaded?

[volumejunkie]

i've pulled more, but its around 7-10k on average. crew cab short bed. gonna make another clip if i can ever find my camera.

[diesal41989]

it soudns bad ass the way it is.......does it smoke alot at igher RPMs or is it minimal? yeah make a new video with no muffler id love to hear that bud

[volumejunkie]

Smokes at low end and cleans up in the higher rpms. it had a tow tune when i made this video.

[SmartyMP8Cummins]

my dad's truck sound's exactly like this. . its an 03 d-max lb7. . .but it has the the stock exhaust and it's straight piped like this one. . and ur right about the smoke thing it does clean up at higher rpm's. . my dad has a superchip on his truck smokes a shit load at take off. . .

[volumejunkie]

In this video i still have the muffler. The tune i'm running now doesnt smoke too much, thanks to McRat.

[SmartyMP8Cummins]

oh realy well. . it's realy loud then . . it sound's like it's straight pipe sorry there

[volumejunkie]

I've managed to lose my camera. I want to put up a video without the muffler. maybe i'll find it one day

[SmartyMP8Cummins]

ill bet she'll sound real good without the muffler. . u got any other upgrade's

[volumejunkie]

Long list. Good tuning, little more fuel and a little more air. All the parts that break between those.

[diesal41989]

yeah they both make more power then the LB7 but i think the LB7 sounds better when running....they get better MPG also

[volumejunkie]

I love the way it sounds, i need to make a new clip of it with no muffler. I've been working on my tuning and have gotten it up to 22.6 mpg average.

[diesal41989]

now see i think that the LB7 sounds the best of all the Dmaxs when its idoling..not only because its much louder while at idol but because it seems like they have more power...the LB7 was the fastest and most fuel conservative of the all the Dmaxs...but other then that this truck sounds awesome man what year is....01-04.5?

[volumejunkie]

actualy the LLY and LBZ both make more power than the LB7 stock. mine is an 04.

[JeremygotTHEmotoQ]

niiiiice brah

[Hotrodx199]

Lb7's sound the best idleing, others dont have the good sound that the Lb7 makes.

[MrExtremepaintballr]

@Hotrodx199 6.5s sound pretty awesome though

[Hotrodx199]

@MrExtremepaintballr Yeah the 6.5s are alright, they sound pretty cool but i prefer the turbo 6.9/7.3 IDI sound, actually i think N/A 6.9 with true duals are the sweetest sounding diesel ever haha

[Jacksonkellyfreak]

@Hotrodx199 i got a vid of my idi turbo 7.3 up. sounds awesome.

[XXMANCHESTER4LIFEXX]

nice sound u should put some stacks then i think it would sound way meaner.

[volumejunkie]

I've had the muffler out for about 2 months now. I need to make a video of that.

[tythesnoman]

what is a turbo-back?

[volumejunkie]

Technicaly it exhaust that runs from the Turbo-downpipe back. Just means a full exhaust without a cat.

[tythesnoman]

Cool thanks!

[DLFATPAT07]

isnt that the same as a straight pipe exhaust?

[volumejunkie]

No, it has a muffler. Well had one when i made the video. It's since been removed.

[shorehamsoo]

not bad for a rice burner!!!!!!!!!

[bobojd93]

See Chevy is awesome...Fords have no power and ok quality and dodge has some power and shitty quality. Chevy has both

[CockYaLegS]

You are seriously stupid.

[bobojd93]

Why because u have a piece of shit Ford...?

[belindaam04]

Thanks guys. Gonna try and get some motion vids this summer.

[volumejunkie]

Wrong user name oops.

[gvfd1993]

sounds sweeeeeet!

[jaskra2]

sounds nice

[DamnTheDoubleNickle]

nope wait i think i miss read you yer sayin its 5 inch from the down pipe back...

[DamnTheDoubleNickle]

im pretty sure you got a 4inch down pipe....so its not 5inch turbo back

[volumejunkie]

Downpipe-back to be exact

[DamnTheDoubleNickle]

so what yer sayin is you got a 5 inch down pipe?

[rodarana530]

sorry, my 6.0 powerstroke has a meaner and better sound than ur LB7.

[z71offroad2000]

that may be true but it still sucks check out my duramax video

[volumejunkie]

Too bad sound isnt the most important thing huh?

[FoxDie262]

Congratulations?

[duramaxjh]

imo duals dont look good on diesels unless its like a show truck

[7fayette]

is the 07 duramax any good/ like compared to the 05 duramax/any changes

[dieslelover]

ya the 07.5 duramax is a lot better but still not verry much changes

[dnomyar0]

one of the best sound dmaxes!

I love it, thanks man

[dieslelover]

that sucks compaird to the mrbp cool dules now that is sound

[gwhunter350]

6.o PSD sounds a million times better

[volumejunkie]

Thanks.........

[7fayette]

what does LB7 stand for?

[volumejunkie]

LB7 is the motor generation. There are four now. LB7 is first then LLY, LBZ, and now LMM.

[louisianarebel]

clang clang pop... sure does..

[walkertejas]

Ya, the sound better if you like to hear engines eating them selves. 6.0 = biggest POS Ford motor ever
