I Straight Piped My Turbo Diesel Mercedes! Loud Turbo Spool & Weird Cold Starts

[@LegitStreetCars]

What do you think? Sound good or not your thing?

[@cyrilmatthew2995]

which engine sounds better ..gas or diesel?

[@monsterram6617]

@@cyrilmatthew2995 It depends. My Cummins sounds like Bigfoot farting continuously into a trash can.

[@jamesofalltrades4359]

It’s better then stock but it sounds like something is loose. It’s a slight wobble noise I keep hearing

[@kash19840]

I had a 535d and did the same thing but in my opinion diesels sound horrible. There best left alone. Just do your power mods but dont expect them to sound good

[@offbeatkeyboardslayer9290]

u should make a 3.5 inch custom exhaust that would make it for all the turbo noises

[@KTM753]

Sounds just like a 5.9 Cummins at idle but sounds better under load. I dig it. Cool video.

[@Niko351]

Nah

[@greggnewton9781]

Nothing like a 5.9

[@thediddlefiddler5569]

wtf? It sounds NOTHING like a five9

[@liamollen3105]

If anything, it sounds closer to a 6.7

[@Ionel88]

A project on the audio side ?? An Improvement of the Harman Kardon System. I would really like to see something like that.

[@MBDieselFreak]

Definitely do a secondary solenoid operated bypass that goes through the mufflers! Makes cold starts and normal every day driving a little quieter. The high load, high rpm straight pipe sounds amazing.

[@jaybudd1617]

What I liked back in the day talking in the 80's era the sound of the Mercedes diesel turbo sound. You could tell there was a Mercedes around instead of one of those G.M. diesel.

[@Porsche996driver]

11:10 apparently this was the first MB with lane keep assist lol.

[@TonytheCarEnthusiast]

When you’re busy you learn to use the leg to steer

[@nikidudev]

Finally! It sounds sick!! I’m happy you went for the catless and straight pipe. Really looking forward for the future progress on this E-Class!

[@dieselgaint]

I'd say add a resonator from an e55 in the middle to take the harshness out the turbo whine. VGT turbos are a lot harsher whistle then a fixed vane turbo. Or the e63 mufflers which would allow more engine tone with damped turbo whistle. My 7.3 psd with a big turbo has a straight through resonator and muffler. Sounds good a the perfect amount of turbo noise.

[@nknasi]

most diesels don't sound better unrestricted, imo. I don't hate it, i just think the same mod on any gasoline car would make more of a difference.

[@standyourground9973]

nknasi Agreed, however the performance gained from removing the restrictive parts is so worth it.

[@murraysaka6603]

It sounds awesome bro!!! Love hearing that turbo spool up.

[@the74impala]

Do something about that red tint in the rear. Boost activate.

[@Dingodil_1]

Fix that metallic rattle.

Sure, transplant a gas engine. Otherwise, that's how a diesel sounds.

[@Dingodil_1]

@ It seems that you're deaf. Something is rattling, maybe heat shield.

It seems that you didn't read the big letters at 9:00.

[@nap8187]

Iñigo Zapata 4:58

Yeah, that's the rattle they fixed by 9:00.

[@vladimirkalinov1181]

Straight piping a diesel is the way to go. I did that to a Mazda 6 2.0d. I took out the cat and the DPF. I chipped it from 143 to about 170 ps. I also modded the airbox, it was quite restricted. My mpg went from 6.5-6.7 l/100 km to 5.3 l/100 km which is a 25% increase in fuel economy. The car feels a lot faster. I think that's all you need to do to a common rail modern diesel: chip tune it and derestrict the intake and exhaust, don't bother with other expensive upgrades. Now, regarding the exhaust: after I decat and de-DPFed it I was left with the muffler only. I wanted to bypass the muffler so I installed a cheap electric cutout. Works great! The straight-piped sound when the cutout is open is awesome. Inside the car it is barely perceptible but nice until the turbo spools up. Then it is quite a bit louder. Outside it is definitely louder but I don't know how much louder since I always drive it. When I close the cutout it is as silent as before.I think the electric cutout is fine for a diesel since the exhaust gases are not as hot as a gasoline engine so the cheap cutout should last longer than for a gasoline where a vacuum activated cutout would fare better. The only negative is that on cold morning the engine smells a bit more. I am considering getting a new better flowing cat and installing it after the cutout or even in place of the muffler. What do you guys think?

[@sirnik84]

In my neighborhood was a lowered truck with a mural on the tail gate of the truck parked at the beach. The truck had a picture of its self on its tail gate! I'm not a lowered truck guy, but that thing was COOL! I bet there was 10+ hours of work in that tailgate. Gotta respect that kind of passion.

[@ExciteLetsPlay]

I have a w202 220 cdi straight piped. Its not to loud, you hear great turbo whistle and the biggest thing is if you cruise on the highway with like 70 on cruise control you dont hear a difference to the stock exhaust its quiet and comfortable.

[@cmine615]

I don’t think the camera does justice, these engines sound great with an exhaust. Good job! Thanks for posting

[@shawnhatfield6579]

This is awesome! If you want more turbo whistle give it an open air intake with the straight pipe. I’ve had a couple of ford power strokes and this set up will whistle! Great job. Loving the videos!

[@ikkem8407]

Did you change your camera because the quality of the video seems way better. But the content as always is the best.

[@ukwan]

Diesels are so popular in the UK they don't really get the love they deserve with enthusiasts, but I've had my fair share of Diesel cars and they're a really nice thing to have, V8 levels of torque with great fuel economy.

[@AMomcilo1]

Sounds like the Audi R18 TDI LeMans race car. It actually sounds really nice, which I wasn't expecting.

[@pedroa.f.c.590]

Definitely it's gonna be a nice mod on this E320 Cdi... I put a straight stainless steel pipe on my Golf GTI (MK 4,5) with stainless steel muffler (mid & end)...but I couldn't even talk or hear what my wife inside the car was speaking...so I got the stock end muffler and put it back again...I think I'm too old for that loud sound, but with this configuration, I definitely can hear the turbo whistles...and it's pretty cool actually!!! Keep us posted with the E63 end mufflers...it's gonna rule...

[@reeewhydoihavetochangethese]

"this is just normal acceleration" meanwhile, out the back window, everyones disappearing with a quickness

[@kylemcweeny878]

Ahhh u beat me to it!

[@rammphillips3002]

Alex, I appreciate your work on this diesel car as I commute 45 miles each way here in San Diego. This would be a terrific daily driver car, good power, great economy! Same thing goes for the 'Eco-Vette" as well! The sound is fine with me. It's there, but not too over-the-top. Fabulous content!

[@stevebarnette]

Turbos are the best mufflers. I straight piped my Porsche 911 (997 C2S) and it shook the windows of my house during cold start in the garage. Because the 911 has a rear-engine layout, there wasn’t even that much piping. It was louder than any race car I’ve heard in my life.

[@southerndiy1]

It’s got a bit of Detroit 71 series rasp (but quieter of course). Love it - I think I want one

[@ponypwr]

Put a cone k&n filter off the front of the turbo your new exhaust tips and call it done! Love it.

[@2006gtobob]

Time to upgrade the fuel system now!

[@LegitStreetCars]

Oh yea! Turbo too, meth injection intercooler, and a bunch of other stuff. Can't wait!!

[@Creek_Hunter]

@@LegitStreetCars You might wanna check the Benz forums, there is a dude from Finland, Tuikku, iirc. He runs dual turbos on one of those. Some 600+HP....

[@thisdudeisnotin]

I like the idea of cutouts. As an aside back in the late 70's early 80's we used to have raging keggers right around the corner from where Driven Performance is. Before they reconfigured the runways at O'Hare my buddy had a house right on Irving Park Road and at the end of the side street, you could see the runways. Good times until some pilot would call the cops because he saw the bonfire.

[@NoWay-vz9xw]

I am a low rider fan, so I have seen paint jobs like this, but this is pretty damn good!

[@ryanharte528]

Add some kind of mufflers. Dyno Max ultralflows or something. And any MPG gains in from removing the cat in the down pipe?

[@jasonciepluch5427]

I have to admit I was ready to hate on this video, but I actually like the more aggressive sound of the car now. Thumbs up👍

[@ventsislavpanov]

One of the best projects on your channel, you had to finish it. These turbo diesel has so much potential!

[@gspadez]

Welcome to the straight pipe club.. I added a x pipe on my e500 left one resonator in the front

[@ROZGarage]

Not a fan of the religious side of the paint, but it looks just GORGEOUS. Way better than a wrap, the gloss and wetness is amazing.

[@zl1le104]

If you want an even louder turbo get a cold air intake. And if you want some boost in power (not much), get a custom intercooler which will keep the turbo cooler.

[@phil955i]

You can actually hear that it's a six cylinder now, which you can't with the stock exhaust. One of the things I didn't like about my E320CDI when I had it. Sounds great, keep it that way. Putting mufflers on will only return it to somewhere near stock again IMO.

[@Michael_Obando]

Those wot drive byes sound like a straight piped 6.0 power stroke. Sounds good 👌🏽

[@furiousdriving]

oooh yeah, that sounds incredible!

[@maxcitytv352]

Dude it actually sounds good ,sounds incredible especially on the drive by , i would definitely straight pipe my cdi if i had one after watching this video.

[@williamscott6847]

I did similar on my 2004 e270 cdi. It sounded super deep and meaty and you could hear the turbo whistle under heavier acceleration!

[@adventurousairman]

I love Diesel Mercedes as I have a few, I really prefer quiet , just drive it !

[@rogerjeck685]

Kinda sounds like a medium duty truck. I'm all for the turbo whistle though. Is it possible to have healthy bit of whistle and quiet exhaust? Also, when is the silver car avail for purchase? enjoy your vids!!

[@jetstream454]

I'd say using a higher performance air filter would have a very noticeable difference.

[@J.F.K.O]

that sound at cold start. i seem to remember watching a vid off a duramax 7.2 having a similar sound at start up

[@BITTYBOY121]

It sounds great ! Very sporty now ! 👍

[@NGAAutoTV]

Another great video Alex!

[@gregh7457]

yea i've seen art on cars like that. 70's california had the van scene with some outrageous murals.

[@davidnjoroge8495]

if you wanna hear 👂 the turbo well,remove the plastic resonator downstream of turbo charger,and the other resinator after intercooler below the intake manifold,i have done this on mine and i can tell you the sound is sick,then modified swapped amg exhaust system,its sick sick sound.

[@fabulousprofound]

mentioned the car cover deal to some other people and they've ordered their covers with your code. thanks!

[@LegitStreetCars]

Awesome! Great to hear!!

[@ja.935g67]

4:17 12:29 California wants to know your location! 🤣

[@monsterram6617]

Give it up, dude.

[@RealityIsTheNow]

Good for California. I remember that brown soup we used to breathe down here before they cleaned the place up.

[@TNBShooter360]

Sounds like a semi-truck 😂

[@lukeselby6576]

Diesel 😂

[@micheldionne5882]

TNBShooter360 yes like a two stroke Detroit Diesel!!!

[@DiscoFang]

Think you need to try resonators where the old mufflers were. Or packed type performance mufflers. Be good to remove the hiss/whoosh and the hollow sound which the packing should do.

[@abdelhameedalotaibi3657]

Would love to see you working on a w219 CLS one day .. its basically an E class with a different design ..

[@standyourground9973]

Abdelhameed Alotaibi That would be a sweet daily tbh

[@kaidiego]

3’ single pipe with a resonator would sound pretty good I think... But if you want the quad exhaust the e63 mufflers are some of the best according to amg community. Pretty cool though, definitely a unique project!

[@petarkresoja3481]

I done this to a poor 220CDi and who is sitting in the back hears a really awful noise...In the front though you wont hear any, but i removed the catalitic converter...but it sounds impressive. Since i have nothing more to do i might put back in a new converter and redo the pipes correctly

[@jockemechanix5801]

9:02 For those who are wondering, the ratteling noise is not caused by some broken/loose part, its the camshaft chain that is ajusted hydraulically when the engine is just starting. The engine need to create oil preassure for the adjuster to tention the chain and in turn quiets down after a few minutes. Hope i was of any help and have a good day.

[@Creek_Hunter]

Not true, the engine quiets in a few second upon starting. I can see on the dashboard the oil level dropping immediately once the engine starts. It's not your typical older Benz. Unless he is using a thicker oil, maybe...

[@Nikonfanboy1982]

My entire life I have always been a huge fan of loud exhaust. Till I bought a house and neighbors knew it was me coming home at 4 am lol so now I prefer a sleeper. I honestly don’t think straight pipes sound good but performance 1st. Does back pressure effect diesel as it does gas? I lost performance with my exhaust system believe it or not.

[@Porsche996driver]

Sounds great. Good work modding that diesel, they’re so overlooked.

[@FCT8306onTwoWheels]

Its a straight six, turbo diesel. Thats super rad, exhaust note reminds me of those JDM Supra and Skylines with exhausts but this is a diesel. Diesels can take it

[@monti-man8207]

Sounds fantastic on the drive by.

[@wardyy8304]

Let’s see some footage of you going snow drifting! #chicagowinters .. Love your videos!

[@DBSSTEELER]

Alex, I would do a single Dynomax Bullet muffler to smooth out some of the rasp. Remember how people used to that with the SLP Loudmouth catbacks on 4th Gen F bodies.

[@LegitStreetCars]

Very good point. I have a couple laying around from my TA.

[@rick62465]

I did the same thing to my 98 c250 td. You can hear the turbo and wastegate very good

[@jclaydon3454]

That sounds really good... I really enjoy your videos. Looking forward to seeing the 320 progress. Keep up the good work.

[@GIGABACHI]

VERY detailed paint job, cringey-fanatic motive but to each their own. SOUND: From the inside it sounds kinda Meh... BUT . . . from the outside at WOT it sounds AMAZING. I love Diesel and I've accepted it's "shortcomings".

[@jonnyrocker77]

sounds like my w210 300tdt with cat and straight pipe ...the sound is amazing

[@JayLang7]

Nice. Was waiting for this video

[@hondatrix]

Alex, the exhaust will only increase the turbo sound a little...it's way too long and the sound waves can't reach the rear intact. Open the air intake and you will hear what you want to hear...

[@fmswatchdo2373]

Exhaust sounds way better. On the other hand, the fleece liner will freeze to your paint, I know for a fact. Those straps ripped away in less than 30 days, that cover is a POS, I replaced with one from Pep Boys.

[@chrisbarrett5132]

I think it sounds like an old truck pulling a heavy load up a hill. I like my 320CDI the way it is, quiet, really quick, and very discrete. Having a loud Merc is just so uncool.

[@muzinkosi668]

Ditto that man!!!

[@c4r5on88]

Amg are loud

[@seanmillar9247]

Sounds great, you've got me hunting for one now to go with my 92 w201 m602 turbo, but the CDI"s seem to be alot fewer in Canada. I can't wait to hear it with the new turbo!

[@EnthusiastCarHangar]

Wish there was a wagon CDI. Great video.

[@jimhopper2246]

Is there any way u can tune it to add fuel? That is where your power is hiding... Sounds best straight piped btw

[@vainoteppo8815]

Jim Hopper u mean rolling coal?

[@freddysmalls187]

I got the 3.5 gonna try this next month can't wait

[@JoesGoldenGarage]

Hell it sounds good to me man. I am so tempted to try and buy your other CDI is it’s not sold

[@Creek_Hunter]

I have the exact model of the silver car. Interested? 170 000 miles and counting.

[@enzopianelli6081]

It sounds like a Messerschmitt bf-109 fly by, that's hilarious Love it

[@SinghM3]

I really like that exhaust cutout idea Alex!

[@mallafakerii]

i wish you saw my e320 cdi that i used to own, straight 6 cylinder engine, man it was crisp, clean and you d like the sound it made.. not to brag but i dont think there was a better e320 in the entire car industry... it was full-extra:Active distance control (distronic),climate controls in the back as well,led tail lights(brake lights), parking sensors on both back and front,it had a roof (not panoramic thoo) etc!!

[@killswitch_disengage]

Direct turbo air intake mounted pod-filter will make the turbo sound hella loud, both outside and inside the car.

[@paulius5017]

Performance intake, or CAI would make the turbo sound lovely

[@roccosvan]

Sounds like my deleted 6.7 Cummins good work Alex!

[@cfrayre6572]

Wow that sounds mean. I have notice you became a fan of diesels engines. That Mercedes sure isn’t your dad Mercedes diesel. Great video. You have so many good resources. I need to purchase the grey cdi from you. Awesome video.

[@pyric]

I think it sounds super quiet even straight piped I would leave it sounds pretty good but not obnoxious

[@twin2xs]

Sounds good Alex. Made me want a cdi

[@hermanshelton3660]

Kinda sounds like an old Deuce and a half. Gives it's character.

[@Fosgen]

I would weld bigger pipes instead 2", more like 3.5" in mufflers place. Fluid flow coming from smaller to bigger inside diameter pipe, must increase its pressure and drop speed. Bernoulli's principle. I have 2" welded to 4" end pipe, single pipe exhaust. Roar is fantastic, on turbo charged diesel.

[@biglovesam]

I bought a silver 05 cdi but was too scared too get it dirty so my mom drives it, then i bought another 05 cdi, then my friend and i flew to Washington to buy her an 05 cdi that needs a little work and she eventually sold it to me, I ended up buying a 06 cdi best codition ever until my girlfriend crashed the frontend. I hope to meet you this spring and track down some parts and share some tunes

[@007Broadcaster]

Who would have thought a diesel could sound so good!!!

[@volvopentaman]

You need to get a W211 E420CDI to tune. Drove a few of those at the local car importer when they were new (among like all models from A150 to S65AMG). The STOP/START button on the 420CDI gearknob made me first think "whiat's this?" I knew that only V8/V12 versions had that. Then i checked the factory sticker. Did a couple drifts on dry asphalt by mistake . :D

[@GAMESTERVISION]

God I love Mercedes.. I own a 2004 Cl500 5.0 V8. 302hp stock ain't had ya know? And it rides so fucking smooth. Once u own a Merc u forever know why they are so we'll known for quality.

[@DiscoFang]

Those drive-bys sounded like an 18 wheeler climbing a rise on the freeway.

[@lengerer]

Sounds good. It’s weird hearing a luxury merc sounding like this, it’s normally only modded diesel 4wd, ha.

[@imre9729]

I straight piped my 2007 E280 CDI if you want you can see it on my channel. I love the sound btw, can't wait for new mods!

[@basithph8958]

Can't wait to see this on the drag strip!

[@SpagettyCraft]

Wait til you hear the 270cdi. Sounds even better.

[@dbnpoldermans4120]

Sounds pretty good cold start sounded mean!

[@shahabuddinX313]

Since it is going to be your daily and because it's a good idea😜 I guess the boost activated bypass valve would be great.

[@stabbs_15]

S124 TD would sound sick :D I like that!

[@CBTBGAMING]

noob question but when you remove the muffler don't you increase your chance of failing your emissions test?

[@ADAMTVawesome]

Possibly
