It really does have the sound of a lil baby cummins at idle. Sounds cool as hell I hope you can get a torque reading when you are done with your mods someday. Great videos
Nice, it isn’t that much louder and I don’t think it will smell bad. And once you get the bigger turbo.. oh my, it’s gonna sound and perform amazing! Really looking forward for it!! Also, 0-60 numbers don’t matter that much, because of the circumstances. You are definitely gaining a bit more hp and torque but don’t expect that high numbers.
You can weld galvanized steel as long as you remove the galvanized coating, and if you don't you risk serious health issues because of the heavy-metals.
The main strength of the car is it's in gear acceleration rather than from a standing start. You will see improvement in your 30 to 60 and 60 to 80 mph times and this is where the 320cdi excels. In the real world this is where you need the acceleration to be? I love it,leaves other cars standing!
I agree that rear bolt is hard to get at. I modified the shield on the two CDI's I have owned by grinding the hole into a slot. Now all you have to do is loosen the bolt, and slide the shield forward. Try it, you will like it!
I believe that you will get an improvement on other speed ranges (from 40mph to 70mph for example). I believe that some mercedes engines are limited on how fast they can raise rotation.
How about instead of modifying the second hand cat by cutting it up just punch out the honeycomb inside the cat therefor leaving it stock looking from the out side .
Cut the pipe's at each end of the cat weld a straight pipe through the cat weld the original pipes back on and problem solved flow issue gone while keeping the stock look.
Love your videos man! Thought - Could you reduce the cat matter material by half to maintain partial exhaust cleansing and still lose that half boost for power gain and remove the muffler for sound quality? Cut a door into your old cat and remove the front filter matter, then mesh what is left and weld the door back on. That is why I need a shop in my garage! So I can further mod my S550.
Yeah, it will definitely stink and pollute more without a cat/dpf. And in ur particular case, no performance gain. What makes me more curious, is a fumes test. With cat vs without cat. To see if it’s worth the weight loss and space gained in the engine compartment
Gedas Alekveravičius Not sure adding a cold air intake would would net any gains due to the fact a Diesel engine prefers warmer air in its cylinders since its compression ignition. Increasing the size of the intake if it’s restrictive could help, but not to sure a cold air intake would do much since the air needs to be compressed and heated in the cylinders anyway to ignite. The new turbo for sure tho will help since it’s forcing more oxygen into the engine , not by means of cooler air but by the amount of air it’s drawing in. Being heat soaked is bad for power but a cold air intake isn’t going to do much. Insulating the turbo, and a better cooling system would be more beneficial .
Hehehe, I've also thought the same😅 but still, even in diesel, colder is better, also if you increase the boost, more molecules in the cylinders, they get compressed even more, even more heat to ignite, so really it would be better
Colder is better for diesel motors? They wouldn’t need glow plugs or a system to preheat the cylinders if that was the case. The only thing in a diesel that you want to keep cold is the exhaust system. EGTs are way more important then intake temps.
The air in a diesel engine needs to be hot enough after compression that the fuel ignites when it enters the cylinder. There’s no other method to ignite the fuel. If the outside air is very cold, and the motor isn’t warmed up, compressing the air doesn’t heat it up enough to ensure the fuel ignites.
@@calebdutka3285 colder is more dense, more oxygen molecules etc, as petrol engines. Colder is better coz more oxygen, so more fuel can burn. Yes engine can run on cold air, it can run on - 50degree Celsius, but yeah, start with glow plugs and it won't run if engine is not warmed up. But compressed air will heatup enough to ignite the diesel, but cold block will not
Wait until you change out the intercooler and turbo, you will hear even more whistle from the turbo. I still have stock downpipe and can hear my new turbo whistling a lot more. I really need to get my downpipe taken care of
Maybe measure 50-70mph or some other metric. Could you get some headers made up to go in all that space you have created? :) Love the channel,good luck with your projects, from the uk
As far as i know you want to loose as much temp as possible right after the turbo to gain power by getting more exhaust gasses away from the hot side(hot air has more volume than cold) so wrapping it with heat isolation can get it worse. What i think would be the best compromise is just wrapping the upper part so the intake does not get as hot as now but wrap it as minimal as possible to get it to cool down as fast as possible By letting it cool down the difference in density will cause like an vacuum allowing more gasses in the same time to get out
Personally to me the exhaust note sounds less but turbo greater. Would rather some engine note personally. Off to watch the next episode in this series thanks Alex
Enjoyed the video, i'm surprised it's not it's not more noisy,base on the way the car is pushing you back in the seat it seems more powerful as well,not sure if it's my imagination,looking forward to the turbo mod,should be interesting.
You should have a LegitStreetCars lane at Byron with just your cars. Grab a bunch of your buddies and convoy it. I'm pretty sure you can book now or very soon. I'm sure a lot of people would show up and buy T- shirts and stickers and stuff.
If you want to change the intercooler, try thinking to put an air to water one. It reduces the lag of the turbine to almost 0. But if you don't or its a to high cost ,let the original one and the new turbo. Otherwise you will have big turbo lag,and a small wide band of power.
Sounds great, mufflers are next to go though.. if you’re not liking the diesel smell, try running a biodiesel blend- B10 or B20 should be fine depending what is available to you.
B10 - B20 is aplenty here in Illinois. Due to the corn lobby and tax incentives it's actually easier to find than #2 diesel. BUT, Mercedes doesn't recommend anything over B5.
I didn't know Mercedes only recommended B5 and lower, I assume that is only on the common rail engines? Old mechanical injection OM616's etc. will run on filtered waste vegetable oil quite happily- as long as it's not too cold, so Illinois in the winter might be tricky!
I'd like to see and performance difference in removing a cat because everything I've ever seen is that unless the cat is clogged there's nearly never a performance change.
Did you mean aluminized steal or is it actually galvanized? Aluminized steal is whats used for exhaust, galvanized is used for fence posts and its toxic to weld on.
sui seidel it looks like the common low grade stainless steel pipe used extensively these days. Calling it stainless steel is wrong, it might be better referred to as rust resistant steel alloy. The aluminized stuff sloughs off the aluminum coating if you weld it.
Hello, love the Diesel Mercedes series, I wonder why not just remove what's inside the catalytic converter instead of welding a new pipe, because of the heat? Will it be any problems if I do it like that?
You have the optil to make a better flowing in and outletcone on the Cat. That would help a lot combined whit a bigger exhaust under the car to the rear mufflers (hot exhaust gasses needs more space than colder gasses.) combined whit better a header and turbo type you could increase the cars potential and drivability. De-Cat is never a good idea. But I maybe been damaged since i work with DPF and SCR systems. It is not easy power its Dirty power. i think that there is better ways to gain power, for example water injection, better Intercooler, cleaning the intake and porting the heads, better turbo, exhaust manifold, better injectors, better Highpressior pump. ECU optimizing. Oil catch tank. If you ajust the engine to make as little sod at possible you will get more NoX but when you don't get the oil in the manifold it would be easy'er to keep it clean. It's not free but is is a better way to do it. You can tune and still be green ish. And when you do that you learn a lot.. Other wise i love the video's one of them help my friend trouble shorting on his W211 e270cdi. Best regard from a viewer in Denmark
Why not just put a higher flowing CAT on there? Honestly though your turbine wheel on your turbo has to be the biggest restriction in your exhaust. IMO it’s not worth it for an extra 3-5 HP. CATs play like the single biggest role in reducing harmful emissions in modern engines, and you’ve shown that just a simple tune has given you more performance than removing this emissions device mandated for every car sold in the developed world.
@jack eagan - bullshit. yet delta and american airlines and twa and every other airplane company in the world run with practically no emmissions and are allowed to fuel dump raw fuel into the atmosphere just so u can take your family to disneyland and they can make a buck? if the government actually gave a shit about the environment they would prevent car makers from changing body styles every year. that sh*t ain't good for the environment ya know! new body panel stamps? headlights? rims? grills? glass?
Hello I have a 1987 mercedes 300d turbo diesel. I believe my cat is bad and I'm thinking about removing it and busting the core out and bolting it back on. Will this set off the check engine light. It shouldn't hurt the way it runs considering its not electronically controlled correct. Any advice or suggestions would be greatly appreciated. Thank you.
I did this to a 335d. I put a DOC less downpipe, 3" and straight pipes all the way to the back. Fuel economy went from 22 mpg to 28.5. It is well worth the stink factor.
I just have the mufflers off on both of mine and it sounds identical! Please chop those mufflers off just to see what the full straight pipe sounds like!!
Not sure about the noise level becasue of the turbo, but i had an old straight 5 cylinder diesel Mercedes without turbo.Once the exhaust broke off in front of the muffler (this was years before stainless exhausts), it sounded more like a tank than a car.
You can get about 265hp/ >600nm from these ,easy. Everything stock, no need mobify anything. Just the ecu tuned. Stock Intercooler is bad as hell, change that first !!!
@@djbarren100 no oem ! They are crap. Aftermarket will work perfect. Cheap ones are excellent compared to oem cooler. You can get good aftermarket cooler bout 70usd
Curious about how you tune it without the downpipe and exhaust modifications. I have an ML 320 CDI and e320 cdi. I have a juice box on the SUV, which is quite nice… But… It looks like there’s more to be had!
Should of built a jig and you could of cut it and welded it back together and everything would have lined up perfectly and if would have saved a ton of time.
Did you see him weld, gross. definitely not a fabricator/welder, they would never think to build a jig. that was my first thought. could have done this job in 5 mins tops.
I believe you should replace the CAT and keep a clean-burning car. If you wish to make any car a 1/4 mile bandit, then remove the plates and just go racing with a modified car. Adding a bit more power without impinging upon the fuel mileage or emissions is what everyone should be desiring. I love diesels but they are a problem since the VW scandal. And, even Mercedes and I believe BMW and most other mfgrs of diesel cars around the world are experiencing the same or similar issues as did VW... false claims from their emissions tests. Mercedes newer diesels like the 4-banger which was touted by Benz as a great design, and their earlier V-6 diesels, were/are good engines but have had their fair share of issues. So, the best diesel by Benz is likely the one in the E320 CDI cars (and trucks) as it is truly bullet-proof... The OM648. Enjoying the videos, nonetheless.
I still mourn the day I wrecked the 1998 W210 E300TD sedan (my first accident after driving for about 54 years). While it had 187k (or so) miles on it, I had it in top-notch condition and it ran very well. On a trip down to Louisiana through Miss, on I-55 I got it up to 90 in a quick spurt and it was purring. Just like the old W126 300SDL we once had. The W210 was pampered by me. I made sure all rust which popped-up was taken care of by a shop every Summer. It had all new brakes (Akebonos), new front roll bar bushings (a PITA to replace by laying under the car), Conti DWS06 tires, used Liqui-Moly oil and filter and other sundry parts on the car from FCP Euro, had fresh tranny fluid and filter, new coolant, new brake fluid, good A/C, an Alpine Bluetooth with microphone and adapter and resistors to take full advantage of the Bose system in the car, and new P/S hoses. The insurance company gave me $6300 for it. I should have bought it back before auction and fixed it, but it was really crumpled in the front (hood, front cross-member, bumper, radiator and A/C stuff, cooler, and pushed in the sub frame rails. I hit a Hyundai econo car in the back doing about 35mph. Air bags never deployed and no one was injured. I had just pulled into the right lane with lots of room and a guy who had been tail-gating me zipped past. I just quickly glanced over to the left not even moving my head, when I caught out of the corner of my right eye the stopped traffic. I slammed on the brakes and even with the great brakes on the car, I could not stop within the 20 or so feet I had. Obviously, I was cited. Since it was 4 days before Christmas and we were driving to our son's in Illinois, there was no way I could coordinate a rebuild of the car. So, when we returned home, I researched a lot of Benzes, even a new CLA250, and ended up with a 2013 C300 4Matic (sport) with the M276 motor. It's a fantastic car, especially in the snow we now have. Very few options on it except for the Harmon-Kardon entertainment package, which is great. I again used the Conti DSW 06 tires and have recently installed new front brakes (rotors and Akebonos) from FCP Euro. Rear pads will go on in the Spring (too dang cold in the garage). I still use Liqui-Moly. The W204 is incredibly stable with the DWS06 staggered tires. Love it... handles like it's on rails... better than the SLK230. Even use it in our 1998 SLK230 kompressor which is now under wraps for the Winter. So, lesson to be learned: KEEP YOUR EYES ON THE DANGED ROAD!!! Sigh.
I am thinking to buy a Mercedes GL 420 CDI or an GL450 CDI Which one has the best engine? And is 200,000KM or 124,000 miles too much? The models I look at have 120k+ miles on them. Hope you could give me any advice where to look for. Thanks!
Thanks for the contend but I dont think folks care about performance on a 07 diesel merc at least I dont. Im more curious about reliability and consumption.
Putting a 3" over a 2.75" and you get a small restriction on the lower end of the straight pipe = exhaust flow will be interrupted and wont flow evenly. Just my $0.02 from Sweden.
Hi Alex I heard in this video that your 320CDI has a stage 1 tune. I have a CLK270 w209 2004 with 174,000 miles with full Mercedes service & parts. What are your thoughts on me getting it a stage 1 tune? Please could you advise? Chris

Just to be precise, in Diesel vehicles is not called a catalytic converter. It is called a DOC or Diesel Catalytic Oxidizer.
its doc with dpf right?
@@antoniotod9614 Yes, only factory option in the US though. Normally the inline 6 just had the oxicat unless you optioned for the particulate filter.
Yes although not DOC had a DPF (dust particle filter). After 2011 I believe due to CARB and later EPA all diesels had to have a DPF and later and EGR.
It really does have the sound of a lil baby cummins at idle. Sounds cool as hell I hope you can get a torque reading when you are done with your mods someday. Great videos

Yikes
Nothing as toxic as NOx !
You can weld galvanized steel as long as you remove the galvanized coating, and if you don't you risk serious health issues because of the heavy-metals.
@@Doomskilled thats why he ground the hell out of it on the grinder before he welded it
Another great LegitStreetCars video. Swap out those mufflers for some Flowmasters and that Benz would sound beefy.
I use to work at an exhaust shop and the reason the o2 wouldn't screw in is bc you welded thr bung in without the cap. It got hot and shrunk.

I wish you would've gotten a sound clip with just the cut pipe how it sat at 7:05
I believe that you will get an improvement on other speed ranges (from 40mph to 70mph for example). I believe that some mercedes engines are limited on how fast they can raise rotation.

Cut the pipe's at each end of the cat weld a straight pipe through the cat weld the original pipes back on and problem solved flow issue gone while keeping the stock look.

Both of them are in single casing, first there is a cat and dpf right after it.
Great video. Very entertaining
Are you going to ceramic coat the car?
Also remove the spare tire and other stuff in the trunk to reduce weight
Hello I have a 1987 mercedes 300d turbo diesel. I believe my cat is bad and I'm thinking about removing it and busting the core out and bolting it back on.
Will this set off the check engine light. It shouldn't hurt the way it runs considering its not electronically controlled correct. Any advice or suggestions would be greatly appreciated. Thank you.
Love your videos! Even more exiting now when you are modifying your CDI because I also have E320 CDI :)
Me too.... Got 40.4 my last tank in Colorado
Hi awesome video, have you any videos of this car from you fitted the bigger turbo?
. . . and the DIESEL GOODNESS keeps pouring . . . 🤘👌👍❤
I did this to a 335d. I put a DOC less downpipe, 3" and straight pipes all the way to the back.
Fuel economy went from 22 mpg to 28.5. It is well worth the stink factor.
Best project on UA-cam
Thanks brother, I'm excited too!!
Listen To That Turbo! Breathe in that exhaust!
Nice job bro from the chi
Love this build. I’m following it closely.
I just have the mufflers off on both of mine and it sounds identical!
Please chop those mufflers off just to see what the full straight pipe sounds like!!
I straight piped my 2002 s320 cdi and it made a big difference (stage 1 map too)
Not sure about the noise level becasue of the turbo, but i had an old straight 5 cylinder diesel Mercedes without turbo.Once the exhaust broke off in front of the muffler (this was years before stainless exhausts), it sounded more like a tank than a car.
Richie Thirlwell any sound clips???
@@natethedrummer91 I don't have any at the minute but I could take one tomorrow if you want to hear it?
@@richiethirlwell9454 Do it and post it, you'll get a few views from here no doubt.
You can get about 265hp/ >600nm from these ,easy. Everything stock, no need mobify anything. Just the ecu tuned. Stock Intercooler is bad as hell, change that first !!!
Is there an after market intercooler for these? Or do u recommend a retro fit from another model?
@@djbarren100 no oem ! They are crap. Aftermarket will work perfect. Cheap ones are excellent compared to oem cooler. You can get good aftermarket cooler bout 70usd
I've mine mapped and have always thought of a bigger intercooler. Think I'll look into it.
@@oukkg Can you please suggest me a good intercooler and AirFilter for this car
@@johnysilvester8483 Intercooler 550 x 140 x 65mm Core Universal, they sell these everywhere, more then enough for this use
Curious about how you tune it without the downpipe and exhaust modifications.
I have an ML 320 CDI and e320 cdi.
I have a juice box on the SUV, which is quite nice… But… It looks like there’s more to be had!
Love this build! I wanna get rid of my alh TDI and get one of these!
I thnk that intercooler is the weak link in any major performance gains. What type of EGTs are you seeing?
Hey I know it’s a while since you posted this, Just wondering is that the 320 with the Om642?
If you cut the cat out, shouldn’t you rename your channel into just “StreetCars”? 😉
no cause legal and legit are two different things lol
Tarnjot Ojla Haha, had to look that one up. Tx!
You should check my 3.2 cdi with out the mufflers, but with the cats
Should of built a jig and you could of cut it and welded it back together and everything would have lined up perfectly and if would have saved a ton of time.
That what i do when changing flexhoses on “nottrowaway” mufflers and cats. I weld Them to my workbench before cutting them.
Did you see him weld, gross. definitely not a fabricator/welder, they would never think to build a jig. that was my first thought. could have done this job in 5 mins tops.
Is that DPF or cat? And did you turn it soft-off?
they got galvanize fume vape yet? make sure you clean your galvanized tubing with brake cleaner next time..
I believe you should replace the CAT and keep a clean-burning car. If you wish to make any car a 1/4 mile bandit, then remove the plates and just go racing with a modified car. Adding a bit more power without impinging upon the fuel mileage or emissions is what everyone should be desiring.
I love diesels but they are a problem since the VW scandal. And, even Mercedes and I believe BMW and most other mfgrs of diesel cars around the world are experiencing the same or similar issues as did VW... false claims from their emissions tests. Mercedes newer diesels like the 4-banger which was touted by Benz as a great design, and their earlier V-6 diesels, were/are good engines but have had their fair share of issues. So, the best diesel by Benz is likely the one in the E320 CDI cars (and trucks) as it is truly bullet-proof... The OM648.
Enjoying the videos, nonetheless.
I still mourn the day I wrecked the 1998 W210 E300TD sedan (my first accident after driving for about 54 years). While it had 187k (or so) miles on it, I had it in top-notch condition and it ran very well. On a trip down to Louisiana through Miss, on I-55 I got it up to 90 in a quick spurt and it was purring. Just like the old W126 300SDL we once had. The W210 was pampered by me. I made sure all rust which popped-up was taken care of by a shop every Summer. It had all new brakes (Akebonos), new front roll bar bushings (a PITA to replace by laying under the car), Conti DWS06 tires, used Liqui-Moly oil and filter and other sundry parts on the car from FCP Euro, had fresh tranny fluid and filter, new coolant, new brake fluid, good A/C, an Alpine Bluetooth with microphone and adapter and resistors to take full advantage of the Bose system in the car, and new P/S hoses. The insurance company gave me $6300 for it. I should have bought it back before auction and fixed it, but it was really crumpled in the front (hood, front cross-member, bumper, radiator and A/C stuff, cooler, and pushed in the sub frame rails. I hit a Hyundai econo car in the back doing about 35mph. Air bags never deployed and no one was injured. I had just pulled into the right lane with lots of room and a guy who had been tail-gating me zipped past. I just quickly glanced over to the left not even moving my head, when I caught out of the corner of my right eye the stopped traffic. I slammed on the brakes and even with the great brakes on the car, I could not stop within the 20 or so feet I had. Obviously, I was cited. Since it was 4 days before Christmas and we were driving to our son's in Illinois, there was no way I could coordinate a rebuild of the car. So, when we returned home, I researched a lot of Benzes, even a new CLA250, and ended up with a 2013 C300 4Matic (sport) with the M276 motor. It's a fantastic car, especially in the snow we now have. Very few options on it except for the Harmon-Kardon entertainment package, which is great. I again used the Conti DSW 06 tires and have recently installed new front brakes (rotors and Akebonos) from FCP Euro. Rear pads will go on in the Spring (too dang cold in the garage). I still use Liqui-Moly. The W204 is incredibly stable with the DWS06 staggered tires. Love it... handles like it's on rails... better than the SLK230.
Even use it in our 1998 SLK230 kompressor which is now under wraps for the Winter.
So, lesson to be learned: KEEP YOUR EYES ON THE DANGED ROAD!!! Sigh.
I'd like to see a rear axle ratio change on this or your E55 to get more power to the ground in the 1/4 mile.
I would think you would put in a form of a shift kit in the trans to go along with the turbo
Any problems passing emissions? I am in Nevada I have an e320 bluetec and am looking to do it what you do to your cdi. Thanks I’m a fan of your videos
I am thinking to buy a Mercedes GL 420 CDI or an GL450 CDI Which one has the best engine? And is 200,000KM or 124,000 miles too much? The models I look at have 120k+ miles on them. Hope you could give me any advice where to look for. Thanks!
You're great guy man.And making good youtube videos.I i'm watching this e320cdi project with big hopes.PS: i love the STANDARD sunroof.
DId you have to code DPF removal out with computer also?
Thanks for the contend but I dont think folks care about performance on a 07 diesel merc at least I dont. Im more curious about reliability and consumption.
What turbo is coming from the UK?
I ask as I’m a subscriber from the UK myself
I told you it would make a difference.
this is what i wanna do with my e46 320cd ,, gunna order a flexy and send it ,
Awasome video did you find a buyer for the silver cdi yet I really want to buy it
Q: Why do you have " Otwórz zasówę " on your wall?
Putting a 3" over a 2.75" and you get a small restriction on the lower end of the straight pipe = exhaust flow will be interrupted and wont flow evenly. Just my $0.02 from Sweden.
Swedes Garage won’t make a damn difference.
It happens all the time with cars, especialy with intake piping etc
Hi Alex I heard in this video that your 320CDI has a stage 1 tune. I have a CLK270 w209 2004 with 174,000 miles with full Mercedes service & parts. What are your thoughts on me getting it a stage 1 tune? Please could you advise? Chris
Hey Alex. Big fan. Quick question. How did you get that annoying fastener off from the back of the heat shield. Haven't been able to figure it out.
Just out of interest does the US get the V6 Cdi engine used in the facelifted W211?? I think the output for the V6 CDI is 228bhp!
Straight 6 in 05-06 CDI 201 HP
@@clagueb3686 thats a shame, the V6 CDI was very very good! And responded well with a stage 1 remap!
I think Mercedes returns to straight sixes this year both petrol and diesel.
Check engine light isn't on for no cat and straight threading O2 sensor on the pipe?
There is only 1 upstream so no. No check engine
@@LegitStreetCars awesome 😁👍
do you guys over there get v8 biturbo diesel? if you guys do! get one ,thats you next car!
