+Luca Car Mods a friend of mine a f-250 that has an aftermarket turbo that sounds like a jet engine but much more define than this duramax even at idle it squeals like a jet
If I were you, I would do the lift and tires next and then see if you still want to do the engine mods with the new driving dynamic that the truck has.
the 5" also lowered velocity though so may not be the power gains a 4" would offer. low bp + high velocity = better power. but, when he puts a tune on it + whatever else he wants it'll probably be best. it's gonna sound great, look good and off road well.
+Kevin Kanzler Exhaust velocity doesn't make a difference post turbo . You want as little restriction as possible after turbo . Just because you want maximum pressure difference to get the exhaust turbine spinning as quick as possible
Coming from a guy who has an LLY and knows numerous other Duramax owners and performance shop mechanics and owners, I'd say yea do your wheels and tires for looks, but for performance, do the turbo mouth piece because the stock one is extremely restrictive (I'd recommend and s&b or a LBZ). Don't get sucked into thinking you need a cold air intake, they really don't help that much, not worth it in the long run. then do your deletes like egr and pcv, and then do your down pipe. Down pipe is something that gets over looked a lot but is very restrictive. It will also add a very nice sound to go with your 5" exhaust. Now everyone will say go buy a tuner, well first of all don't just get a tuner, get EFI Live, but before you do that, I HIGHLY recommend getting your transmission built. It will save you the headache later. One last thing I forgot to mention, get a lift pump. Doesn't have to be an expensive one, as long as you don't want to go over the top you'd be fine with a simple raptor.
I purchased an 05 lly crew cab in silver birch back in August. I already did a 4" MBRP exhaust, egr delete and the lbz intake mouthpiece, all of which were very straightforward. This spring I'm looking at American eagle alloy 20x9 wheels, cognito leveling kit and kory tunes from ppei with the edge cts2 to monitor.
Loving the build so far. I would recommend the lift/wheel tire install before the tuning and intake just to make sure everything is tuned perfectly for the truck. Exhaust sounds amazing as well. Can't wait to see what you decide to go with in terms of wheels and tires. I'm running Fuel Kranks on Terra Grapplers at the moment, but would love to switch to American Forces in the future. Keep up the awesome work.
Very nice exhaust! If you want a suggestion for tires, I would suggest Patriot Tires. Awesome tread pattern, and has a lot of ply layers that will last for a long time!
MBRP down pipe is a must on these trucks. You will notice far bigger gains from the down pipe then the exhaust. Not to bad on the install and youll see better Egts and Mpgs.
Nice job! The turbo whistling comes much more to live now! How is it in US - can you do just any degree of loudness without getting trouble? Here everything is really strict. But your exhaust would be probably still ok in Germany. It's good to have someone with experience in you reach! And it's awesome to get someone recommended, who knows!
I go to the desert with one of my good friends and he has this exact truck and he put a 5 inch straight pipe. I've never been so turned on in my life when I heard the thing xD
I have the same system on my LB7 but I cut the tail pipe short to make it an axle dump. The echo of the exhaust off the ground makes it so much louder.
Truck sounds amazing man! I have a 2003 ( lb7 engine ) and I love mine! I have EFI Live by Kory Willis and I really recommend him for tuning! EFI Live is the best programmer you can get for these trucks! I also have a 5 inch mbrp straight pipe to a 7 inch tip and I couldn't believe the difference. Good luck on the build man!
Don't need to pull the crossmember to get the cat pipe out. Remove the hanger that's bolted to trans (2 13mm) and it'll come right out towards the front of the truck.
PCV re-route is cheap and easy. After you get the egr bypass put in it wont matter but you might as well do it. Also look at the pump rub kits for the transfer case. The best part about older trucks is other people have already found all the gremlins.
am I seeing this correctly that this thing only has thirteen thousand some odd mileage?!?! thing sounds amazing, I absolutely love this body style, probably one of my all time favorite body styles.. can't beat the sound of a duramax when it comes to diesel trucks imo
i have a 2004.5 lly iv had for about 6 years efi live and all that bullshit i did alot of work to it years ago ...I made a custom 4 inch strait pipe for her that comes out in front of the right rear tire for about $40 bucks and sounds better than any full run exhaust plus I think it looks cooler ....wish i would of said somthing about it before im sure you would Dig it > Nice Job thou Mike
Looks/sounds good! I like how you chose to cut the end of the exhaust back to get the tip tucked up under the truck. I see some around with the tip sticking way out past the bed side and it looks ridiculous.
Thanks. Its kinda a low mileage/nice find like yours. Ive owned it since 2010 and only has about 58k miles. Originally from Alabama/old man driven and I've done my best to keep it out of the Ohio salt here. Still all black and rust free underneath. Did some subtle mods and replaced a lot of swap parts and maintenance and it stays in the garage a lot as a spare/annoy the wife vehicle when I buy stuff for it. Lol.
So I guess since your truck is pre-dpf, there are no tune issues when you remove the cat? What tune are you planning on doing? Next question: are you still going with 35's, and if so, do you need to lift it or are you just doing a levelling kit? Sorry for all the questions just curious how mods on a GM compare to other trucks.
Gotta give you some good advice, if you plan on doing a lift sometime, DEFINITELY go with McGaughy's 7 inch lift and 36 inch tires, 20x14 Fuel Maverick wheels would look SICK on that truck. Cool video, and Love the Dmax
Down pipe clamps are always a bitch! Even on my bmw it was a pain. Good updates dude. You're slowly making me desire a duramax and I don't even own a truck!
Sounds awesome. Not that it matters, but you'll lose a little bit of low end power by increasing the diameter of the exhaust (reduces exhaust gas velocity which reduces the scavenging effect).
5 inch pipes allow the vehicle to breath better. giving better are flow and passably even better millage. bigger pips will effect sound making the vehicle louder but honestly to me thats is a good thing lol.
You should upgrade the down pipe off of the turbo because it can increase flow which causes faster turbo spool and thus more power. Also, it can lower your EGT levels.
Did you get any CELs from the swap? How did you avoid the light? Also, noticed you live in PA. Is there emissions for diesels? And how did you manage to get a shop to do it? Sorry for all of the questions?
Egr delete and efi live👌🏿 tuning is better done sooner than later cause at any time it can throw that engine code and put the engine in limp mode but seriously nice truck sounds good can't wait to see how it turns out
I did it on my lly with it just up enough for the tires to hang 😅 it took a whole Saturday with a buddy. but I got diamond eye and it was only 340$ with a 5 to 8 inch tip for 55$ black :) it's in a axle dump setup with my 20x10 wheels and 33x12.50r20 nitto mt tires. I would do a lift wheels and tires before engine work since it's the most noticeable difference. mine is only leveled with 33's but with the exhaust it gets down on power. efi live tuner coming in 2 weeks
+Drews Tech And Reviews Sounds like our build goals are pretty close haha, upload a video when she's all done! I have truck update coming again in a few days :D
Yeah it seems that way!! I just had a little head start to since I got mine a little before. Do you have a instagram , I can send some pics on the Dm part if you want
Following this closely. Did you get an after market air box with the exhaust or is that on the list. Pep boys, I'll have to check them out. Also the Tool Shed between Middletown and Elizabethtown can order stuff as well. Including wheel and tire packages!
I like watching your videos they're very good but I gotta wonder why you bought an exhaust system for the pickup but cut the one on the Hellcat I would have done that the other way around
get a tuner then get a EGR delete it will make it louder and open up the truck more, because when they come factor they are starving for air because all the emission stuff that they have to come with
watching this a year later because I finally got a Duramax. I think exhaust is my first mod
The turbo whistle is amazing.
I like that it almost sounds like a jet engine with the straight pipe exhaust! 👌
+Luca Car Mods a friend of mine a f-250 that has an aftermarket turbo that sounds like a jet engine but much more define than this duramax even at idle it squeals like a jet
Fix Or Replace Daily
FORD
+LAD Fan ik I hate ford but his truck is awesome
If I were you, I would do the lift and tires next and then see if you still want to do the engine mods with the new driving dynamic that the truck has.
+Curtis Hickerson if I were you.. I'd do the tune first then do the tires/lift if you still want to with the new driving dynamic lol.
no. re gearing the axles
+lamar jamar *no one without a kiddie brain
Real good choice in exhaust for all the "off-roading" you'll be doing. Lots of ground clearance.
The power you are feeling is the catless downpipe! Great work, exciting build! Keep it up, Mike!
It's not your mind playing tricks. You just free'd up a bunch of back pressure in the truck which in turn helps the turbo spool up faster.
the 5" also lowered velocity though so may not be the power gains a 4" would offer. low bp + high velocity = better power.
but, when he puts a tune on it + whatever else he wants it'll probably be best. it's gonna sound great, look good and off road well.
+Kevin Kanzler The 4 or 5 will not make a single difference. The turbo has a very restricted down pipe on the Duramaxs. Only difference is sound.
+Kevin Kanzler Exhaust velocity doesn't make a difference post turbo . You want as little restriction as possible after turbo . Just because you want maximum pressure difference to get the exhaust turbine spinning as quick as possible
I love the rumble at low RPM and the higher RPM sound is amazing! The turbo whistle is fantastic! Well Done Mike!

Forgot to mention head studs. But that isn't a cheap bill, so might as well built the whole motor while the cab is off 😂
This... Tuned by kory Willis or Idaho rob
+Derrick Howard Thank you for being the first person on here to actually know what they're talking about. I've got an 04.5.
+Derrick Howard You're gonna love my next update video coming in a few days :)
I purchased an 05 lly crew cab in silver birch back in August. I already did a 4" MBRP exhaust, egr delete and the lbz intake mouthpiece, all of which were very straightforward. This spring I'm looking at American eagle alloy 20x9 wheels, cognito leveling kit and kory tunes from ppei with the edge cts2 to monitor.
I can tell this truck has a ton of potential and will look really good when its finished. A great truck to build/
Have been watching this channel for about a year love your work man keep it up 👍🏻
I've never been so happy to see another update video for your truck lol
I loved the corvette, and love the hellcat but the truck videos have me wanting more! Keep it up man!
lol it went from sounding like a school bus to a garbage truck 😂. sounds awesome though
+ninecool11 Like a fast garbage truck ;)
+Street Speed 717 are you ever going to tune the truck
+Merica lover Patterson He said he would.
I don't why but I enjoy these truck videos more than your Hellcat videos and I LOVE the hellcat..keep up the amazing content bro!
+Shehryar Ehtesham haha thanks man!
Loving the build so far. I would recommend the lift/wheel tire install before the tuning and intake just to make sure everything is tuned perfectly for the truck. Exhaust sounds amazing as well. Can't wait to see what you decide to go with in terms of wheels and tires. I'm running Fuel Kranks on Terra Grapplers at the moment, but would love to switch to American Forces in the future. Keep up the awesome work.
Love how you're documenting the mods! Brother was thinking about getting an exhaust for his 05 LLY and this might encourage him to do it
+Mark Schaefer thanks man! have him follow my build haha I'm hoping it becomes a good guide for people once it's all done!
+Street Speed 717 Do you notice very much more in-cab noise over stock?
The content, production quality and editing in your videos are really improving! Great video!
cant beat the sound of the VVT turbos on the 04.5+ duramaxes
Very nice exhaust! If you want a suggestion for tires, I would suggest Patriot Tires. Awesome tread pattern, and has a lot of ply layers that will last for a long time!
The Duramax sounds great with the new setup! I am new to the channel, and your videos are great!
I got the same exact system on my cummins without the tip and I feel more power than before! It's Badass!
+Anthony Johnson Nice! Buddy just got the same for his 04 5.9 I hope to have a video for s sound comparison soon!
+Street Speed 717 That's gonna be bad ass!
+Street Speed 717 Mines a 01 5.9 24v, the older ones sound great up until the 4th gen with the emissions bs.
MBRP down pipe is a must on these trucks. You will notice far bigger gains from the down pipe then the exhaust. Not to bad on the install and youll see better Egts and Mpgs.
Crazy that I now have a lly and have been looking for exhaust clips for a 5 inch and I remember watching the video when it came out lol
Changed a lot in a year
If you take the passenger side wheel well out the clamp is right there takes 5 mins 😂
+Ryan Driedger Yep noticed that afterwards lol
I met Martin Barkey (owner of mbrp) at a imsa race once. He drives a really cool Camaro and it sounds amazing
If you haven't yet you should look at a cognito lift with bmf wheels wrapped with toyo mt's 35 12.50 R20 that would look awesome!
I think a grill would look great on your truck!
Nice job! The turbo whistling comes much more to live now! How is it in US - can you do just any degree of loudness without getting trouble? Here everything is really strict. But your exhaust would be probably still ok in Germany. It's good to have someone with experience in you reach! And it's awesome to get someone recommended, who knows!
"I don't like when you see a gigant tip sticking out" Said the man with the 7" tip :)
Man that's a clean looking truck on the underside, I have a 01' same config but with the 6.0 and I wish she was as that free as yours!
+nathan harland benefit of only 13k original miles :)
+Street Speed 717 Ohh my goodness! I bought the truck new in 03 and right now she has over 350k miles, still whoops most trucks out there
Haven't watched it yet but damn thats gonna be loud. Will it fit on my Miata? lol
+Gingium were gunna need a built vs bought on this...
Bubba Junior LOL I should do a built or bought with a truck!
+Gingium lol 5 inch pipe on a miata would look perfect!
Street Speed 717 I can guarantee it wont fit lol, but a 5 in tip might actually be decent?
SS717 the type of guy to buy a Bugatti and trade it back in a month later.
And get his hellcat back from the Bugatti place
+Preciƨe Vids Maybe someday ;)
Bugatti is an ugly car
Best Mod, definitely doing that on my 2002 Duramax !!
I go to the desert with one of my good friends and he has this exact truck and he put a 5 inch straight pipe. I've never been so turned on in my life when I heard the thing xD
Finally. ;)
Thinking about making a youtube channel for my f150 ecoboost.
if it is not a raptor no one will care
+Swaff Corps (Theswaff699) I might care...
+tstraw48 Boom. 1 Sub. haha.
Oh too bad you didn't buy a a 5.0 or 6.2 v8
Dodge 318 Cummins Didn't want one.
I did race a raptor though. Not as fast as my eco lol
I have the same system on my LB7 but I cut the tail pipe short to make it an axle dump. The echo of the exhaust off the ground makes it so much louder.
Truck sounds amazing man! I have a 2003 ( lb7 engine ) and I love mine! I have EFI Live by Kory Willis and I really recommend him for tuning!

+zSiNIPeRx3636 Thanks! Tuning coming very soon.
Intake exhaust tuning. Makes the truck a lot more fun.
No efi live makes it more fun lol

am I seeing this correctly that this thing only has thirteen thousand some odd mileage?!?! thing sounds amazing, I absolutely love this body style, probably one of my all time favorite body styles.. can't beat the sound of a duramax when it comes to diesel trucks imo
+Alex Diel yep! It was a pretty rare find haha
Man that sounds awesome almost makes me want to get a diesel

I approve of the exhaust choice
Looks/sounds good! I like how you chose to cut the end of the exhaust back to get the tip tucked up under the truck. I see some around with the tip sticking way out past the bed side and it looks ridiculous.

Awesome man loving the truck so far! This is really random but is there any way you can make more videos on investing?
So I guess since your truck is pre-dpf, there are no tune issues when you remove the cat? What tune are you planning on doing? Next question: are you still going with 35's, and if so, do you need to lift it or are you just doing a levelling kit? Sorry for all the questions just curious how mods on a GM compare to other trucks.
Would love to see this truck fixed up, lowered with 20x12s, and making 1000hp. Racing urus’s
If you're considering doing an undercoating, I'd recommend some mud flaps as a much better value and better functioning vehicle condition protector.
glad to see man you've reached 45 k subs keep up the hard work
I think the truck looks great just the way it is! But what do I know, I'm a keep it stock and simple king of guy.
Just found your channel - glad I did, great content! Look forward to your future videos (:
+Dominic Bradley Thank you kind sir!
I still cant get over it only has 13k miles on it!! One hell of a find!!
I know right. I'm so jellyyyy. But I can't wait to see what he does. I like his taste in vehicles.
I think this set up with a slight 100hp tune will be perfect for my black bison 🤞🏾🤔🦬🦬
Gotta give you some good advice, if you plan on doing a lift sometime, DEFINITELY go with McGaughy's 7 inch lift and 36 inch tires, 20x14 Fuel Maverick wheels would look SICK on that truck. Cool video, and Love the Dmax
+LeveledLariat Update on wheels and tires has been posted :)
Very nice choice! Going to look awesome
Down pipe clamps are always a bitch! Even on my bmw it was a pain. Good updates dude. You're slowly making me desire a duramax and I don't even own a truck!
+Brandon B Glad to hear it haha you'd have fun!
Sounds awesome. Not that it matters, but you'll lose a little bit of low end power by increasing the diameter of the exhaust (reduces exhaust gas velocity which reduces the scavenging effect).
This truck sounds amazing
Man thats a clean under body.
Nice video Mike. I love all your videos!!! Keep it up!
another great video keep the truck updates coming !
7 inch tip! Holy shiz! Careful the bulldogs don't get stuck in there!
5 inch pipes allow the vehicle to breath better. giving better are flow and passably even better millage. bigger pips will effect sound making the vehicle louder but honestly to me thats is a good thing lol.
I have that same set-up on my LBZ with a 6" stainless tip. You should also see a 1-2 mpg increase on the highway.
I can't find a 5" straight pipe from the down pipe back for my lbz it's an 06 deleted but you can't find a kit for no cats for that year
Nice dude it sounds good. getting the MBRP system for my 15 colorado next week.
+snooplikesbacon Nice upload a video of it I'd love to hear what they sound like!
You should upgrade the down pipe off of the turbo because it can increase flow which causes faster turbo spool and thus more power. Also, it can lower your EGT levels.
Did you get any CELs from the swap? How did you avoid the light? Also, noticed you live in PA. Is there emissions for diesels? And how did you manage to get a shop to do it? Sorry for all of the questions?
It's pre-2007 so I'm pretty sure it didn't have as much emmisions garbage
+Techommentary I mention that at the end o the video but nope, no cel and PA has no emissions for diesels :)
+Street Speed 717 tint game weak!
Egr delete and efi live👌🏿 tuning is better done sooner than later cause at any time it can throw that engine code and put the engine in limp mode but seriously nice truck sounds good can't wait to see how it turns out
+Braden Moye yep I actually had it checked, there is an egr code and a turbo underboost code in there, so tuning will be happening very soon haha
Get a ranch hand front bumper/grill combo and a ranch hand rear bumper. Make it look hella. Or get an Iron Cross, Iron Cross is ORGASMIC
3 inch downpipe will increase whistle and spool up, you NEED the LBZ mouth piece, those 2 things should be bin on your list
+Kevin Rogers video coming soon ;)
this model chevy duramax is definetly my favorite trucks, but in my opinion theres nothing that sounds better then a straight 6 cummins.
Gotta hand it to mechanics man ........ Never is easy ....... LOL ....... Sounds bad ass by the way :D
definitely like the new kit sounds awesome
+chris lucy Thanks!
Exhaust will boost performance in a diesel be chase of the fact you can more more air and and the temp runs cooler
the reason it has more power is because on diesels because of the turbo the more open the flow it the better performance you will get.
Sounds like a beast
Kool man, can't wait till the next update 👍😆
Sounds great!
+AimlessMoto Thanks!
+Street Speed 717 when u gonna roll coal

I did it on my lly with it just up enough for the tires to hang 😅 it took a whole Saturday with a buddy. but I got diamond eye and it was only 340$ with a 5 to 8 inch tip for 55$ black :) it's in a axle dump setup with my 20x10 wheels and 33x12.50r20 nitto mt tires. I would do a lift wheels and tires before engine work since it's the most noticeable difference. mine is only leveled with 33's but with the exhaust it gets down on power. efi live tuner coming in 2 weeks

Yeah it seems that way!! I just had a little head start to since I got mine a little before. Do you have a instagram , I can send some pics on the Dm part if you want
It sounds even louder now than this video, is it still the same exhaust or has there been more changes since?
Following this closely. Did you get an after market air box with the exhaust or is that on the list. Pep boys, I'll have to check them out. Also the Tool Shed between Middletown and Elizabethtown can order stuff as well. Including wheel and tire packages!
+TNiss54 Yep tool shed is awesome haha, air intake and engine mods coming soon!
Hey! Just wondering what gimbal you got for your GoPro. It does a great job!
Thanks for the Video !! Street Speed i might get the Pipe that you have For my Dad's Truck LOL
freaking love these videos
Should get EFI live installed next on it, that would be your best tune for a duramax
Sounds really mean!
+subaruwrxfan Thanks Matt!
Looking and sounding good man!!
Cool videos! What camera/microphone are you using for this video? Thank you!
Now, get an exhaust brake if it didn't come with it stock even though you have no need for it. It sound awesome
Cheers from Shippensburg.
Another great video, you might want to considering the license plates of the vehicles when you film..
Street Speed 717 why did you get rid of the exhaust?? Or why did you cut it off underneath the truck? Did you do a video on it? I may have missed it.
exhaust on diesel lets everything breathe way better and does give you a little power
I like watching your videos they're very good but I gotta wonder why you bought an exhaust system for the pickup but cut the one on the Hellcat I would have done that the other way around
get a tuner then get a EGR delete it will make it louder and open up the truck more, because when they come factor they are starving for air because all the emission stuff that they have to come with
Awesome video Mike!
