I Hate the F80 M3 SIightly Less - Can I make the S55 sound good? 

I want an entire series about cars that Phil hates, and then modifies to hate them slightly less.

Love the fact you want a car to sound good not loud!

Kudos for disabling the "burble" with MHD. When MHD were in the Beta phase for the F-series cars there was lots of beta tester chat about the "burble" and I was really please when it became adjustable from utterly stupid to disabled. Disabled box ticked! 👍

I agree with you about the sound. I feel the B58 and N55 sound better, and 2JZ and RB26 were able to sound great with 2 turbos.

I think what you really need to try is fitting a large resonator to exhaust because res deletes are that one mod popular among younger audiences (who are all about that terrible rasp loudness and pops n bangs) that makes all BMW sound bad. You can find some clips for f80 resonator mods on YT and one short also features some backbox mods. In my personal experience it fixed the infamous metalic rasp problem on my personal car m54 with equal lenghts

Loved it when you said, probably upset the internet & walk past your epic lambo & Porsche you developed & created. Standard is boring, unique is better 👌🏽

Definitely interested in the downpipe !

I usually don't send kind remarks when hearing a modified yet horrid sounding exhaust, but you've actually done a fantastic job in tuning the exhaust note of the M3. I really like it.

Really interesting series of videos Phil, I'm sure there will be a decent market for at least the equal length 2 into 1

As others have said, love the fact you're focused on it sounding good (less bad) and not loud. Keep up the good work as always! Also the parking signs are class 😂

Definitely interested in your catless downpipe setup. Amazing that you were able to get it figured out, and all these other exhaust companies couldnt

I'm sure you already know, as it's pretty commonly done on e9x/f8x, but changing the front trailing arm to a solid bush, and fitting adjustable rear toe arms makes a massive difference in reducing deflection (especially under braking), with little/no nvh increase!

If you can manage to make it sound good and then market what you come up with far a sensible price an m4 might be on my next list. Keep up the good work.

Single turbo twinscroll conversion probably will do the trick for the sound uve been looking for

If anyone can fix that sound 🎉 I’m sure it be you.. your find that way .. lol then everyone will want your exhaust system.. praying 🙏 you make it happen… I’m a fan of the oem sound of a e46 m3 cause that’s what I have and will love till the end of time 🎉🎉🎉🎉..

I did a res delete on my M2C and personally I like it. Everything else is standard. In normal mode it’s quiet and is a bit louder than normal in sports plus. If I run engine in sports plus but gearbox in standard it doesn’t over run as badly. I would only consider 2 to 1 downpipe with sports cat as I don’t want to remap. My days of heavy modding are well gone. Great vids!!!

Single 3" sounds fantastic on S55. Helps with less resonation and a deeper tone

4:24 even though it’s not perfect, I think it sounds so much better than any catless dp or cat/axle back exhausts that are available to this day This custom 2 to 1 dp is really doing a great job considering the amount of space you’ve got to work with back there !

10:15.. are we just gonna ignore the new murci?!

Thank you for this! I don't have an F80, but the sound has been the biggest reason for not getting one and I've always wondered why no one has looked into merging the DP like you have done. It sounds like that DP has made a MUCH better base sound and gives me hope though, so definitely looking forward to more videos about this.

I have a similar setup on my F80. I found that changing to the GTS tune sounds pretty good. I know the burbles are debatable however with the time software I’m using you can adjust the aggression and duration of the burble or turn them off completely. I have my aggression turned up all the way and the duration at .3 seconds. With the DCT shift setting in 1 it actually sounds pretty cool on downshifts. Maybe give it a go next time you fiddle with your map.

I think the single turbo ones seem to sound better. It maybe just one of those things you have to put up with mate ha!. Crazy how similar the air pump sounds mate!

Hello from Germany! I think the Sound is quite good with the special Downpipe, midpipe and speaker Sound delete. The Backbox can't have that big of an effect. A Straight-Through Muffler right behind the Downpipe and a another one as a Backbox would interest me. Thanks for All the nice Videos! ✌️

I love this. BMW guys where I live think that simply just making it loud A.F fixes it.

The valcetronic designs equal length into single midpipe exhaust in titanium has the smoothest and most colorful sound I’ve ever heard on a M3 F80. You should watch their video on YT. This convinced me!

Love the idea of the 2 in 1, just wish it could be truly equal and still fit. That would do wonders for the sound

I have a full Akropovic system on mine, sounds amazing & saved a shed load of weight!👌

Love the fact that the burble fart and shart is gone..😂 Nothing screams bellend more than that stuff. 👍🏻

The air compressor was exactly spot on 🤣 I wonder if adjusting the idle rpm slightly may alter that sound. Not a perfect solution lol it must be another unequal exhaust length between the banks since the manifolds are slightly different. But since the air compressor sound didn’t change with the merged down pipe and mid-section, maybe it’s just some side effect of the difference in turbo manifolds’ unequal runner lengths (on the same bank).

Just bought an F80 and couldn’t quite describe the sound. You hit the nail on the head (other than shit) air pumps. I was going to purchase a scorpion but I’m going to watch you to see what your findings are.

Totally agree with you regarding exhaust and maps. I can only assume the BMW engineers all drove crackle mapped golfs when they designed this exhaust

First, absolutely YES to the Work VS's.... even though I absolutely love those particular stock BMW wheels on a black M3 like your own, but if you're going to replace them, couldn't see something much cooler than a set of VS's honestly. Secondly, I'm not a super long-time viewer, so I must of missed your collection....seen the fantastic with widebody, seen the 964 but forgot about it lol, but never seen anything else, especially not that '64 Impala Hardtop (owned a '65 myself when I was 14-17yrs old over 20yrs ago)....sick collection man, and I'm sure that 64 is worth a pretty penny, especially being over there in the UK, lowest you could get one here in the states in decently clean condition would be like 50k, and definitely not a W big block car(don't know if that's what you got though, just heard big block and was assuming it was original, either the 348 or 409ci W Block)

Probably a bit late now, but Phil, have you thought about the 4N Motorsports single turbo S55 kit? Not sure if you're shooting for the power they make, even on the smallest turbo, but they can sound rather impressive.

Depending what youre going for, The raspier and more piffy, run twin pipes as far back as possible into a backbox. For a deeper sound merge as soon as possible and run a large single. As you well know (this is more for others) straight through piped perforated mid box (twin or single depending on what youre doing) will settle the drone. So many people put those silly bullet things in mid way and wonder why nothing happens. It needs some box volume to help messy up the sound waves properly. A lot of the final sound is dictated by the rear box chamber design however.

I love the idea of your front pipe. It seems like an efficient way to achieve equal length!

Sounds good imo, but I can understand you think it’s too loud with the valves open. I love that you turned off the burbles, they just ruin the sound when they are as excessive as the stock ones. If it’s just a single pop or two I think it’s much better than popcorn. I think the stock backbox does create some rasp and tinniness, I have kind of the same sound on my 440i with a catless dp. I want to make a custom backbox for it some time and not just do the double res delete that everyone does. Also that air pump was absolutley spon on for the idle sound 😂

The more equal length downpipes made the sound from the firing order a lot smoother. But the exhaust note has too much high frequency sound and not a lot of low frequency. I think if you could cancel out more of the high frequencies it would sound a lot better. Usually a straight through fiberglass packed resonator cancels high frequencies no?

I used Flowmaster 200 Cell metallic substrate cats. They are 409 not 304 but fairly priced compared to others if deadset on running a cat. Of course , I run ressonators as well (Aero Exhaust)

Clocked you in this last week on the Stratford Rd. Looked and sounded pretty good if you ask me, pre modifications to by the sound from it now.

Id be curious to hear what it sounds like with a different back box/muffler setup. Just stick a single exit one on like you did when testing Viten

Coming from an M140i with the glorious sounding B58 to my new to me M4. Definitely agree the S55 needs more tone. If you manufacture something, please let us know and I'll be making the drive to see you!!

I’ve purchased a few exhausts in my time , if money wasn’t an issue I’d be going to Berkshire and seeing Matt Simpson and getting the best in the UK.

Love the content. You weirdly look like you could be Sam Sulek’s dad lol.

I admire your consistency and perseverance in this kind of projects💪in addition to the high technical level and skills

hjs 200-cell downpipes, single mid pipe with 2 small custom resonators (or Akrapovic titanium midpipes if you can't be bothered botching up your single mid-pipe), and Akrapovic titanium muffler. That's as good as you'll get it to sound.

Most English RU-vidrs I can’t stand . This guy is one of the most least obnoxious cool down to earth sounding guys I have come across . Keep up your cool content !

Should of bought something with an N54 in it, something low mile! I just ordered a 6466 doc race single turbo kit for mine! Buy a top or bottom mount single turbo kit for that F80! There’s a ton of options out there now! The kits are out there starting at under 5 grand & the port injection, injector controller (Motiv/reflex) & stage three pump will set you back another 2k. So for around 7-7.5k depending on your options, you will have a nasty machine & it’ll sound incredible with a big single on it! ✌🏻💯🏁

incredibly excited for this build with the work vs and lowering it!

I can't unhear this air pump noise now there's a few m4s in work and this has ruined it for me 😅

Phil and his quests. great entertainment

I’ve seen the HKS stagger setup on the s55 cars and who doesn’t love the sound of a 2JZ

its the same thing with the E46 M3. first time i drove it, i thought there were parts rumbling in the mufflers (metal ratling) later on i knew it was a engine vibration noise that wont go away, just part of the motor constuction. exept for more or bigger mufflers.

removing overrun would be first thing for me in any turbo m car sick WS wheels,

Interested in the downpipes and the exhaust system in general you fabricate…. I want to achieve the same sort of sound you’re looking for if it’s possible..👍

air pumps XD I laughed way too hard when you turned the Impala key

I’ve tried quite a few different set ups as agree the S55 sounds awful . Quite pleased with mine now, equal length resonated mid pipe (OPF delete) and rest of system standard with cold start delete and no burbles (via BM3). I’ve been through the process of different combos of decats, PCW backbox, Miltek Equal length but just stock plus resonated equal length and mapping out burbles best sounding imo.

Man what you need is an EQUAL LENGTH MID PIPE. It will make the s55 sound like a race engine. Like a gt3 with turbo spool. It will FIX the sound. Autotopnl did a video on one and it sounded REALLY nice.

I took my M4 to PCW exhaust mods. S55 isn't the best sounding engine, or a great engine in general, but I personally like the tone.

The before sounds actually pretty good, it has that straight 6 smoothness The test exhaust sounds a bit odd? Not bad but confusing? adds the factory roughness back in

I believe the S55 "air compressor" sound is because of the stock exhaust manifolds. Cylinders 2 and 4 appear to have really short runs for each manifold which would probably create that "pulsing" you're describing because of the difference in time it takes for those pulses to hit the turbo. A lot of people prefer the N55 sound and the biggest difference is the 6-into-1 versus two 3-into-1.

The tone drastically changed, sounded waaaay better but bit too loud. The MHD burble is horrendous...😂. Looking forward to the next vid.

Will say it again, I love this project it’s about the quality of the sound not the volume. I will be interested in the setup for once ready especially if it will pass MOT with a GESI cat. I also hate Shart and Fart!!!!

Sounds a lot better already. I’m the same as you, I thought maybe m4 for my next car but they sound awful, especially coming from an RS5 V8!

Put a resonator in the mid section. It deepens the sound and removes the high frequencies.

I’m sure I just saw this f80 in Devon this morning? Looked and sounds very very similar

I think it sounds really good with they turbo down pies you made 👌

Standard exhaust with valves unplugged is probably the best solution.

That burble tune is absolutely horrific. Why are manufacturers adding shite burble tunes to stock cars. Unbelievable how bad it sounds and this is supposed to be the s65's successor.

Very little rasp, love it!

I’d be interested in the downpipes

2:20 actually sounds okay and non turbo here.

Wander if the internal noise is noise cancelling and when you put a different exhaust it may actually amplify certain frequencies making it sound worse. Hence why it sounded better when you disabled it.

Deffo interested in the downpipe

Hay take my advice remove down pieces and leave secondary cats on and it will be cleanest sound u can come close on any car

Get your fab guy to make a single 3in exhaust from the downpipes back. Add a big resonator and a fart can muffler.

That’s why igot rid of my old m4 got the new xdrive one it does sound an wee bit better but would love you to take an look at her to see what you could do

Jays E30 looking sweet!

A group buy on m3cutters would get this off the ground. I'm sure you would get a few takers. In my opinion the F80 is really spoilt by the sound, I am completely with you on the improvements you have made, it actually makes me consider an F80, but let's see what's next, tough to improve when you have e46 M3 or e9x M3 for reference... 😁

Would love to hear how it would sound with an equal length mid pipes. Would straight up sound like a 2JZ🤞🏽🔥🔥🔥.

I ended having to put spacers on my bracket because of the piping hitting it constantly. I dont know if that was a good idea structurally but it sufficed haha

I get it, most car people hate EVs my biggest hate is simulated exhaust sound, it just proves that modern regs are stifling cars, I also can’t stand the fad of titanium pipes on rotaries, think it makes them sound tinny and horrible, (that and all the kids thinking a rotary has to sound like a brap machine)

i agree with you Phill they sound broken indeed !

It must be a BMW thing. I was out for for years, having (as a kid) heard some banker type floor his E46 up the road and it sounding just like distortion. Since I have grown to appreciate they are the best driving cars in the class. However, I'm stuck with a rs4 because of the boot and I'm too poor to afford a new M3 touring 😂

I’d love to hear the single turbo conversion on this

@ 4:56 you could of just put spacers on the brace it’s self to clear rather then heating and squaring off the midpipe 🥲😅

Single turbo s55s sound good

single turbo is the way to go, and please get rid of burbles/popsbangs shite! 🙂 Edit, came to the point where you removed that. Thank god!

Nice job

manufacture the downpipes if it makes sense, the market is definitely interested

Not sure what bmw does with their back boxes…its almost like they are engineered for drone with the multiple chambers but lacks enough perforations for sound waves to get to the sound absorbing material. I think the biggest straight through muffler you can fit that has perforations the whole way with heavy packing will help add some needed depth to it.

I cant believe how close that airpump sounds to the F80

Single turbo for this baby, will fix the sound!

Get an Active Autowerke's equal length midpipe or a Valvetronics V2 equal length system and pair it with stock or high flow catted downpipes and call it a day.

Gobshite Mode 😆😆😆 I literally laughed out loud, wifey was like: WHAT

I really hope a similar downpipe can be made for the G80 competition. Love the car, but the equal length offerings for the G80 just don't sound as good as those available for the F80 & I feel a more equal length downpipe could help further smoothen out the sound as you've demonstrated with your F80.

I’d be interested in those downpipes

Love the cars

You can try the equal length midpipe setup for the m3, works magic

Sounds like fiat 500 abarth farting into water.

In the sense that the n54 being twin turbo and also doesn’t have the best sound… my dad has a 135i with the n54 and they did a custom exhaust with two cherry bombs in the middle and a valvetronic muffler at the rear. With no cars so straight downpipes to the cherry bomb and then the muffler, it sounds amazing imo. But i dont know what would happen if you did the same to the s55, whether it would translate the same as it did to the n54. But I know FOR SURE that the single turbo route makes the s55 sound much better
