Muffler MOD for w212 e63. PERFECT AMG SOUND! DIY
The goal was to increase the volume, yet maintain the original "AMG" sound.
Take a little work, but I'm happy with the results!
Comment below!
Also show how to remove the rear exhaust from a w212 Mercedes
Goal. Increase volume without changing sound/tone or looks
Tools, Just an Ev12 socket(or 12pt), sawsaw and a welder
Time, 2-4 hours.
Cost: $18 for SS butt-end exhaust clamps, link: amzn.to/3mKYp1T
Outcome. Its hard to tell from the video, but there is a noticeable increase in sound. specifically on cold start up, low revs and WOT. Its not dramatic but that isn't necessarily a bad thing, this isn't an 3rd gen Camaro lol. To my personal taste, its about 50% of the volume increase I was looking for. I will likely address the resonator later. I think its unrealistic to get crazy sound without addressing the catted downpipes as well
One thing I came to the realization of is, compared to other exhaust (example, the w211 e55), there is very little attempt by MB to deaden or absorb sound in the factory system. SO pulling random numbers for illustration, a stock e55 exhaust only allows ~15% of the sound potential out, so gutting will provide a huge increase. In the contrast, the stock w212 e63 system already lets out ~80% of the available sound, so doing this mod gets you up to say... 90%.
The aftermarket alternative like EISENMANN, renntech, FI or capristo etc for $2500-$6500.
The other popular options are to delete the resonator or the mufflers, or both. These are very good options, but there are a few cons that made me pursue other options. Cosmetically, You're at the mercy of to exhaust shop for the quality. Many of these I've seen will just use mild steel with crappy non-mandrel bends and even wrong size pipe. You cannot really DIY either unless you have a pipe bender. So this muffler mod method looks stock, its quite un-intrusive, reversible if needed. It also wont throw any flags if you need to take it to the dealer if that's a factor to any of you.
Its very popular among other car circles, such as corvette, bmw, w211 e55 and even ferrari guys.
There is possible more potential if you have time to do some R&D. You could try closing off that first Y that just dumps into the cavity or weld a pipe that goes from it to one of the tips etc. I have a feeling it is related to sound quality, so for now I left it.
My future plan is to cut open the top of the resonator and do something similar to to. However, since clamps wont fit, I will just cut a 3" pipe in half and weld it to the outside of the internal perforated pipe and close it back up. Someday i may get downpipes and at that point I dont want it too-loud either. so I may not touch the resonator

Man love your sense of humor in these videos. I just sold my Lexus GSF and picked up the E63. Looks like I’m in good hands with DIY stuff for it.
I enjoy making these video, just wish I had more time. Anyway, the red one needs everything lol, lots of videos coming
I am pretty impressed how you actually come up with ideas to make your job a lot easier and to have more control of what ur working on nice job 👍
Wow, both of those cars sound great. Can't wait to try this on mine
Wish I was handy enough to do this! Great sound that doesn't take away the signature AMG sound
Thanks for this. Very helpful as I’ve been trying to get more sound out of them but wanted a thorough review before hand. And great job grinding and polishing the top of the mufflers!
I wanted them looking untouched. I've been debating whether or not to do the resonator as well, but it depends on if I'm going to do downpipes. Downpipes will increase the sound, so I may want to leave the resonator in place so it's not too loud.
Been waiting for this video. Thanks!
Looking forward to the new videos. You got my favorite combo. AMG+ manual Ferrari
Best before/after on the best car. Thanks man!
Thanks buddy!
One of the best before/after comparisons of any exhaust system I've seen. Also do you have two of them?
Thanks, it's a bit hard to tell the difference through just a cell phone speaker. I wish I had 2 lol, I have two friends local that have identical e63s
Wouldn't clamping the inner pipe still restrict flow and noise? Seems like it would act like a venturi. I love the thought process. I think I am gonna drop the muffle and weld in a straight pipe inside the muffler when I remove the resonater.
Just want to say the E63 videos are fantastic. I'm very lightly toying with getting one to replace my 2021 Stinger GT. Tough to get rid of a great car with only 10k, but... V8 biturbo.... Anyway your videos have given me some confidence I can get one with some mileage and not be totally screwed.
Thanks man! They are great cars, but I agree, they would be expensive to be dealer maintained. Thanks for watching, be sure to hit that thumbs up
Very helpful to see inside of those cans.
I think I'm going to try to do the resonator later this month
Everything about this video is genius
Thanks buddy. I'm still pleased
What a fantastic video bro!!
Thanks a ton!
Nice job. Well done
Thanks a lot!
I removed the resonator only and used straight pipes. $200. It’s all you need to do and it sounds awesome.
Great content. Should have way more subscribers.
Maybe some day haha. Thanks!
@@ExoticCarDIY I just got the E63 AMG S and love it. I’m using all your videos. So easy to follow. Also a FL guy. I’m here in O Town.
Outstanding job as always! I really like how you show short clips back to back. Do you have a tune?
Thanks, no tune. Both cars are otherwise bone stock. Definitely interested in getting a tune, just wary of the mail order types. I'd rather just get it locally tuned on a dyno
Excellent video, now go for the downpipes 😎
Planning on it!
@@ExoticCarDIY nice 💪🏻
Perfectly good infotainment
Thanks for watching!
Thank you so so much for sharing with us this great video and tutorial. Because of you, i will try to do the same. Just one question please. Do you think it is possible to open the muffler not on the top like you but at the bottom ? so when it will be in place it will be not possible to see the mod
Yes, I think you can open them up on the bottom. I just wanted the world to be hidden, that's why I opened them on the top
@@ExoticCarDIY awesome, didn't expect a so Quick answer 😍 so the other pipe inside the muffler won't give harder work to Access , because with your video it seems Closer the bottom and seems to hide a bit the one WE need to mod.? Thx again, so nice.
@@tld-airgunsalafrancaise5965 good point, I'm actually not sure if you could get the clamp-on if the pipe is really closer to the bottom side than the top. To be honest I haven't watch this video and over two years lol
@@ExoticCarDIY Thank you so much, it doesn't matter, i won't take risk and i will open like you have done. You are great thx again
Sounds great! Although I personally prefer the factory sound. I know the difference is minimal, but still... I really enjoyed the mod though. Thank you for sharing!
Yeah it's definitely subtle, I basically wanted the factory sound just plus 10%.
6:50 I feel that ngl
I really commend your creativity here most people would run from doing anything experimental to a mercedes. It seems like the amg uses a turbo style muffler I wonder if the Y that goes into the main muffler body gets sucked back through the perforations and exits back out the tips. I am trying to figure out what to do with my m273 engine (5.5l na) which actually has more of an american muscle sound when I remove stuff. I wanted to get something more similar to the amg sound that is more raspy/crackly but still manages to be deep and not obnoxious... also as you say has more of a tame idle tone which I like.
I considered that, but that fiberglass mat was thick and the holes so tiny. There is no flow IMO. I think the Y either allows some reverberation or absorbs a pop? I really don't know, so that why I just removed the think I knew absorbed sound. In my new one, I'm going to do the same mid, but to the resonator and see how it sounds
Do you need a tune on stock car for resonator removal??
Hello my friend, I'm from the Kingdom of Saudi Arabia. I watched this beautiful video. I would like to ask you. I have a Mercedes s580 2021. I would like to modify the exhaust sound to amg 63 sound by your experience. Is it possible and how to work, so thank you for that.
Curious, do you have any raspy or crackle exhaust note after doing this? I don't want that straight-pipe crackle you hear in some videos. I love the deep OE sound, which is even retained with downpipes only with a OE everything else. Did that deep sound retain and just become a few decibels higher? Thanks!
If you look through some of the comments, some people are critical cuz it did not sound crazy loud with crackles and pops... but to me, it actually is perfect. It is the stock sound, amplified.
Great video! What do these cars use for the extra noise at startup? There are no baffles right? Love how it sounds at startup, but after about 30 seconds I'm always a little sad haha. I would love to just keep that startup volume!
IMO is not possible to have a big loppey idle like a American V8.. e63 has just to tame of a camshafts. My CTS-V idle was so loud compared to the AMG. Yah, there are no valves, I assume cold start is just extra fuel or something. I am curious myself if anyone knows the specifics
@@ExoticCarDIY Extra fuel and retarded timing. I have downpipes on mine and its pretty loud on cold start. Sounds ace. The reason is to get the cats up to temp fast as possible
Perforations!
What is the spoiler wing name I need that one please 🙏🏻
I love the video We’re you a Seabee?
I was not, but I have some family members that are/were
Removed the rear mufflers on my E63s wagon. Absolutely love it. Almost sounds like a truck at low speeds/rpm and really agressive at high speed/rpm. When you let up the gas you can really hear the turbo spool. Kinda boring tho that you cant rev the M157 engine like the M156 when your standing still.
Do you have downpipes? One of the reasons I didn't totally remove them out the resonator is it might be perfect until you do down pipes... Then it will be too loud at that point
@@ExoticCarDIY No i took the easy way to get more noise and still Co2 legal. Its tuned to 660hp 1100nm. Sure it Would be great with race cat downpipes but way more expensive than catless
@@danielwesther3634 which tune? I tried Eurocharged, but it wouldn't shift right in S+
@@ExoticCarDIY A Swedish/Norwegian tuner here where i live. Had no issues at all
@@ExoticCarDIY did you have a tune from Eurocharged Canada or the Eurocharged from Houston?
Should I just drill holes in the back box?
hey I am trying to understand the difference in removing all of the fiberglass, adding the clamp, and then leaving the fiberglass there which would be the stock setup and sound obviously. what's the science behind the addition of the clamp vs removing all of the fiberglass? and what didn't you like about removing all of the fiberglass?
The fiberglass is sound deadening. Sound waves are reverberating in the pipes until they get to the perforations, the sound escapes and is quieted by the fiberglass matting. Removing the fiberglass would kind of make an equity sound, putting the clamp on it basically negates the preparations, essentially making a straight pipe
Meisterschaft cat back is a good option
Dude, 2 W212 E63s? Wtf...im jealous.
Haha, I wish. No I got one and then took my best friend for a drive, he bought one next week LOL
@@ExoticCarDIY Ahhh makes more sense now, perfect for these before and afters though. Great channel btw.
Cool video, way to rep SS717 too
Haha, maybe I could do some matchbox car giveaways lol
The end note on the exhaust sounds alot more abrupt and snappier. I say it sounds damn good
Thanks, so far I like it. Like I said, a little more subtle than I was expecting, but it definitely sounds good
@@ExoticCarDIY i like the fact that if i were to go to a Merc dealer for service they would have no clue what the hell is going on lol
@@JizzleDaMan true, I especially want to do the resonator in the same fashion. So when you look underneath there, you'll see the resonator and wouldn't know it's changed at all unlike having a giant ghetto muffler shop put an x-pipe on there
3:27 I would replace it with an X Pipe and the Mufflers with the Valvetronic Universal Mufflers with the remote to open and close the valve
Remote valves would be awesome.
I removed the resonator and it’s perfect. Very angry.
I have a Slk 350. I will take out the fiberglass for sure. I am not sure about covering the perforation holes. I think my muffler is more like you’re E 55. You increase is three decimal points by covering the perforated holes. Question So how many decimal points do you think you would have had, leaving the holes open? If three decimal points is closing them. Your video is amazing your explanation spot on . like you I don’t want to change the sound I just wanted to increase 25% Or 30%. Again thank you so much for an excellent presentation. Alan
It's hard to say exactly, again I'm going to muffler expert I'm just making educated guesses, I believe the sound exits through the perforations and is absorbed by the fiberglass. Simply removing the fiberglass would allow the sound to kind of echo inside the muffler can. Closing the holes likely gives a different tone. Overall it was pretty subtle
@@ExoticCarDIY Really appreciate you getting back to me. This is a little off topic would like to ask about your E 55 experience with muffler Modification. Did you close the The perforated part of the pipe. And take out the fiberglass . How much increase in sound and change of sound all together . And were you happy with the outcome
@@alanbrylawski2066 on my e55, gutting the mufflers was at night and day difference. Before it was like a Tesla and after it sounded awesome. Most of the information I used came from mbworld. The path of the exhaust in the e55 mufflers is almost comical, it does like 6 180s. The procedure is similar, I cut a 6x8-in opening in the top, and essentially cut off the pipes in the middle, so the exhaust had a free path the float through the muffler and out the back.
Don't tell me you did all this work and didn't start the car with open exhaust even once?! Great video, excellent editing for comparison, and great mechanical work too! Edit: Nevermind, found it! 😂
Lol, glad you found the video. Hell yeah. That's the best part about installing any exhaust is starting it without the exhaust!
I am interested in seeing you do the resonator delete in addition to this.
Yes, I will do the resonator likely in a few weeks
@@ExoticCarDIY why not keep res on and do muffler delete? keep res on since it has H-pipe inside also it has some sound dampening which reduces exhaust drone and just do muffler delete, this setup will give you deep rumble on high revs and quite deep tone on low rpm’s. E63’s rear muffler’s are nothing special, previous Cls63 and C63 had way better mufflers.
@@livebig6414 it's where my personal preference meets taking it in progressive steps and trial and error. I'm not looking for a straight piped 3rd gen Camaro sound... But, do I want it a little bit louder than it is after this mod? Sure. So I will a likely continue with a couple more procedures to achieve that. I also did not want to hack up the stock system and weld on some ghetto rust mild steel pipes among other reasons. I also put more weight on tone than volume. Either way, I'm never seeing anyone do this before to this car, so now we know what it does
@@ExoticCarDIY Yes, I love these videos, I always wanted to see what's inside an AMG muffler as they spend a lot of money on exhaust sound development. But I still don't think muffler delete will make the exhaust sound like Camaro, 5.5 has very deep rumble and turbo whistle, so just deleting muffler will give you deeper tone on high rev's and nice burble on low rpm. Look at new AMG exhaust's, they all have valves that opens mufflers to straight pipes, yes the muffler's still exist, but they damp a lot of sound and when you open valves it's basically becomes muffler delete. Look up on youtube I think some guy called Matty125 or something did just a muffler delete and it sounded awesome. C63 6.2 was the one that had very good back boxes and made the AMG sound unique, but it was naturally aspirated. In your case I would have closed the Y-pipe inside the muffler or made the pipe a little more restrictive and opened a little bit more the area where straight pipe goes, it would be quite similar to what new c63s exhaust looks like inside. But anyway, looking forward to an upgrade/update on E63 as I find exhaust's to be very interesting.
Resonator makes a difference you can hear, pulling the fiber out of the muffler, not really any difference. Do both and see what it sounds like . I bet you get some good noises then.
Would you know if a 2012 m157 cls63 muffler is the same as a 2014-2016 e63 muffler?
No, I don't. I would imagine the m157 sedans share the same design, but I've never seen any photos/vids
Which location u shop
I wish I knew someone like this in the Seattle area that knows how to work on E63s, that’s not the dealership
Seattle? Couldn't be farther away haha. I think initially my main motivation to learn was simply I refused to go to a dealer and get hosed. Now I truly enjoy working on anything. Give it a shot
I have a 14 plate E63, very well looked after, but I just can’t get that brutal sound when gear changes! Btw I’m almost always on ECO and still sounds great but nowhere near as good as yours in stock! (Before muffler modification). Any tip would be appreciated!
Have you ever heard you car from the outside? Like filming or tunnel etc?
Unfortunately I haven’t, no, because I don’t have any camera like a GoPro to set up, nor do I trust a friend to floor it since I’m in the UK and we only get the RWD version 😂 A few days ago I was driving on the highway for a good couple of hours so the engine was pretty warmed up and so I would floor it to get to higher speed every now and then.. I had the windows down to try listening to the gear changes but nothing.. just normal shift with feel of a push at every change.. perhaps I need carbon clean maybe? it’s done 85,000 miles so far
@@ImperialHDGaming Just remove the resonator, $200.. You will get a sound you are looking for. Mine sounds perfect after doing it.
@@jimdandy9118 thanks for the tip! I’ll speak to my mechanic about it he’s a Mercedes specialist! I just don’t like the idea of messing with it since it’s stock
@@ImperialHDGaming As long as you keep it you can add it back if you want but you won’t. The mufflers staying make it look stock so nobody would even know you removed it.
I deleted my resonator with two straight pipes on my w218 cls63, does this mod essentially do the same thing? thanks
In my opinion, yes... Maybe lol. Essentially yes, by putting that clamp over the preferred area of the pipe, I have created a straight pipe for the exhaust flow, however I left that first Ypipe (that dumps into the main can) open. I debated closing it off, but opted to leave it open hoping it was related to the sound time however It's possible it may reduce the sound. I likely will do the same mod to the resonator as well, just taking it progressively
Nice cars, what size rims do you have?
They are oem 19s.
Thanks for the reply, I'm asking because I'm on the fence btwn 19s and 20s. I have a 16' 350, if you had to do it again would you stay with 19s or 20s?
@@JTSBMW I edited the reply since i thought this was in reference to a different car. Anyway, they are OEM 19. I am happy with the size and wouldn't go larger on this car.
Probably sport cat downpipes could help too
Yes, I've heard down pipes can make a big difference in sound. But you need a tune
@@ExoticCarDIY an excuse to get more power easy north of 700hp, I don’t feel the need to do down pipes for my gls63 amg just yet, it’s loud enough
@@tippy35075 I actually did get a Eurocharged tune, but had a bad experience, they just couldn't get it running well. Runs perfect stock. I'll try again later with a different company. Gls63 gotta be awesome!
@@ExoticCarDIY that’s unfortunate, here in aus dad tried out Celtictuning but it was on his straight pipes 02 sl500 so it made little different because n/a, the gls is really good, its start up is programmed very differently, it comes on very smooth in every mode

@@ExoticCarDIY yas clamps
@@ExoticCarDIY thank you very much for helping me I find in Amazon think
what is the exhaust conceited of, cats, res, muffler, is it 2 muffler, 1 res?
Main cats, (some cars have secondary cats) then a single resonator, and a single muffler on each side.
I am going to do this MOD, but I don´t know why did you use a clamp? I don´t know the purpose. Thanks
To seal up the perforations on the pipe. That's typically the way a muffler works, sound waves go through the holes in that pipe and get absorbed into a fiberglass material. By putting a clamp over the perforations, you are essentially creating a straight pipe where no sound can get absorbed. This is a popular mod in a lot of different cars, you can also weld a pipe in its place, or actually weld up each individual hole. I prefer the clamp since it's removable and easy If I was to do it again, I would experiment with capping off that smaller pipe that dumps into the muffler. I have a hunch that that may add a bit more sound
@@ExoticCarDIY ok. Thanks a lot

Hi bro I cannot find the clubs
Thank you very much I did the project and it's very nice I like the sound of my car now but there is one question please I want to ask you what did you fix for the engine you can't hear the sound of the turbo
If I do on a. E350 2016 v6 do you think it will sound like this e63 ??
Unfortunately no, it will sound similar to what it does now, just a little bit louder only
What diameter of clamp should i buy?
I used this exact one. 2.5" amzn.to/3mKYp1T
Turbos are inherently great mufflers. I started my '15 Wagon with no exhaust and it's not much louder.
Ya, agree
Lol where'd your find TWO!!!

@@ExoticCarDIY I perfer my content to be unedited anyway 🫣
Has your 63 been lowered with Lowering links?
Coils up front and links in the back. I actually have a video on that, check it out! Thanks
@@ExoticCarDIY cheers thanks!
So the resonator delete is no good? I have a 2012 cls63 amg
I think a resonator delete and this muffler mod would probably sound ideal. However if you had non-catted downpipes, it probably would be too loud. That's the only reason I haven't done the resonator yet, still trying to decide if I want to do down pipes or not.
@@ExoticCarDIY I have stock cats, haven’t done downpipes yet
@@Amg_Trini It all comes down to how much sound you want, the downpipes, resonator, and mufflers all do a part in quieting the exhaust. My plan is to take them out one at a time and stop when I think the sound is right.
@@ExoticCarDIY I may start with the resonators and see. I’ve seen a few videos with that done and it’s not to bad.
How much did you lower your E63?
I have another video on my channel showing how I lowered it. H&r advertises 0.75 in. But it's actually a little over 2". I'm actually coming up with a way to raise the nose up about half inch. It's a little bit too low
@@ExoticCarDIY just front springs and what about rear? How to lower?
@@OGYELLOW yes, springs in the front, there are two ways to lower the rear. If you have access to somebody with a Mercedes tool, they can dial in the height to request. Otherwise you can do mechanically with "lowering links." Typically found on eBay for about 60 bucks.
These cars are pretty good for $35-55k but a 2017+ M550i xdrive will equal the pre 2018 63 AMG cars in 0-60 and even 0-80. So for about similar $ one can have a M550xi, less $ to maintain, no air suspension, lighter by 400 lbs and 500-523 hp stock with 0-60 in 3.6 sec. And a simple tune will put it to 625-660 hp and destroy any modded pre-2018 AMG 63 car's.
Its just amazing that BMW's M-package cars and suvs are just destroying real AMG vehicles. Never thought I'd see the day non-M car's/suv's could beat a real AMG. No need for a real "M", when a non M will do the job. And real AMG's are the 63 models. Genuine AMG product are built in Affaulterbach. No place else.
Buy what you want lol. Having said that... comparing times from the same source. 0-60 E63 3.3 M550ix 4.0 1/4 E63 11.6 M550ix 12.2 Not exactly "destroying" anything as the bmw is quite slower. And with a "tune" is not fair unless both are tuned... Which in that case puts there e63 in the low 10s. Either way, I'm not partial to any car, not an I selling anything. Thanks for the comment
Just put downpipes and leave everything oem
Seems like a lot of experimental work for very little audio change. But you tried.
Perforations, not Preforations!
Sorry four my pour preformance, im knot a perfessional lol
@@ExoticCarDIY clever 😉
You should have told me you were doing this, I would given you a hand. Let me know the next time you are doing something like this.
I'll probably leave it this way for a couple months and then do the resonator if I feel like I want a little more sound
@@ExoticCarDIY resonators look identical to mine, and they did nothing. Next step is a total gut out of mufflers. m278's sound almost identical to your m157 with the same exhaust ( same platform). I don't have mufflers on mine. I will have you listen to them. I am warning you though, you will get to meet your neighbors one way or another after removing them.
@@S.Madman lol, Good thing I don't have any close neighbors lol
Just remove the resonator, $200. You will get a growl but not obnoxious. It’s the true AMG sound that you hear with the newer models. Straight pipe where the resonator was, don’t H pipe.
Do you have any sound clips by chance?
@@ExoticCarDIY I just have my C63 sound….the E63 with the resonator removed is almost the same when you open the exhaust on the C63 but doesn’t have the pops. I’m pretty sure there isn’t a resonator on the E63 and C63 starting in 2017 and that’s why the sound is better….I’ve never looked under my C63 to verify that though. I used to dislike driving my 2016 E63 until I removed the resonator
I appreciate watching you but when you’re talking about mufflers please understand that it is called PER-forations! not PREFF-orations when talking about small holes in pipe. Otherwise, rock- on brother!
Delete the resonator for true dual.
I just did the resonator delete , added an x-pipe… Mines a 2016 e63s like yours . Butt dyno sure feels like a bit more torque. Sound is about 15% to 20% louder. Same tones and pops just louder . Again your videos are 1st rate .. thanks !
I'm very curious how the sound is with an x pipe... Have you recorded any sounds clips?
@@ExoticCarDIY yes, I have them on my work cell . I will get them to you as Soon as I figure out the KZhead app . , it’s all new To me… will say the tone is a bit more raspier… still has that Perfect Amg sound .. Little bit louder… Not obnoxious mustang 302 Blair.
@@mikeshubnell5797 many of the straight piped m157 sounds like an old truck... I'm thinking an Xpipe might be a bit more refined but louder
Hardly any difference. Maybe a tiny bit.
You really have to listen to it with a good set of speakers or headphones.. Having said that, it essentially gives the stock sound with a little bit more volume. Either way, it's a very popular mod on a lot of other cars, now you know what it will do to one of these. Obviously you'll get some more if you do the resonator as well
i didnt here the difference
Yeah, I kind of explained it at the end. It is definitely different in person, but it is subtle and harder to distinguish using cell phone audio. I'm going to either do the resonator or down pipes next
Congratulations you just ruined your muffler to make it cheaper you made it more expensive 🤦🏼♂️
Waste of time just cut the mufflers
No real change really in the exhaust sound competition.
Almost no change in sound 🙂 you just wasted time and money. But respect for the effort!
Sounds much better stock. Crazy how dong dongs think they can achieve better results with a guess
